  • WEBINAR: Tribal Sovereignty in the Colorado River Basin & Beyond from 12pm to 1pm.  The 30 Tribal Nations in the Colorado River Basin are sovereigns. What does that mean? Roughly two years in the making, a recently released, collaboratively authored policy brief from the Water & Tribes Initiative (WTI), Tribal Sovereignty in the Colorado River Basin and Beyond, addresses this fundamental question. Framed around the WTI policy brief, this WRRC Water Webinar will offer an historical perspective on Tribal sovereignty within the United States; delve into foundational principles of modern Tribal sovereignty; and examine Tribal sovereignty in practice, both internal governance and intergovernmental relations, with special emphasis on the 30 Colorado River Basin Tribes. Animating the webinar (and policy brief) is the view that greater understanding of Tribal sovereignty is much needed across the basin community. In light of the climate crisis and its profound impacts on the basin’s hydrology (i.e., aridification), this understanding is indispensable to developing and implementing the cooperative measures required now and in the future to sustainably manage the Colorado River.  Click here to register.

CV-SALTS maps a path toward long-term salinity management

“Salinity is already affecting the Central Valley’s water supplies, agricultural lands, and communities. It has forced the retirement of hundreds of thousands of acres in the Westlands Water District and other areas. In the Tulare Lake Basin, farmers have relied on active evaporation basins and Integrated Farm Drainage Management Systems to capture and contain saline drainage water. However, these interim measures do not provide a valley-wide solution, and a long-term salinity management plan has yet to be implemented. If left unchecked, salt accumulation could impair millions of acres of productive farmland, reduce food production, and constrain the growth of Central Valley communities.  At its October 6 meeting, the State Water Board received an update on efforts to address salinity through CV-SALTS, which includes separate salt and nitrate management programs. The presentation focused on the Salt Control Program, a phased effort to manage salinity impacts in surface water and groundwater. Presenters included Angela Cleaver, Central Valley Water Board program manager for the CV-SALTS Salt Control Program; Rachel Gray, executive director of the Central Valley Salinity Coalition; Tom Grovhoug, technical lead for the Salt Control Program; and David Corey, board chair of the Central Valley Salinity Coalition. … ”  Read more from Maven’s Notebook.

Parts of California’s coast are vanishing 70 feet at a time

“California’s iconic seaside cliffs are rapidly crumbling into the sea, according to a new study from UC San Diego.  At the Lost Coast Headlands in Humboldt County, researchers found that the cliff top eroded by 22.3 meters, or about 73 feet, per year between 2016 and 2023. Cliffs in Point Reyes National Seashore retreated by 10 meters, or just under 33 feet, per year over that timeframe, according to the study.  The four California counties with the greatest amount of coastal cliff erosion measured were Humboldt, San Francisco, San Mateo and Monterey, researchers found.  Adam Young, a coastal geomorphologist at the UCSD’s Scripps Institution of Oceanography and a co-author on the study, said a main cause was large landslides in Northern California. In 2024, a landslide at the Lost Coast Headlands disturbed over 1.4 million cubic yards of rock and soil, according to Scripps.  “Tall coastal slopes such as those located in Big Sur in Monterey County and the King Range in Humboldt County can increase the potential for large landslides,” Young wrote in an email. … ”  Read more from the San Francisco Chronicle. | Read via Yahoo News.

Trump’s cuts have exposed US to ‘cascade’ of El Niño dangers, experts warn

“Sweeping cuts to the premier US climate agency under Donald Trump have severely hampered the country’s capacity to forecast, research and respond to extreme weather events, former government officials and scientists have warned, as the US faces a cascade of hazards fueled by a potentially historic El Niño this winter.  From the start of his second term, the president has taken aim at the National Oceanic and Atmospheric Administration (Noaa), slashing staff levels, canceling contracts and grants, and shutting down databases and research laboratories. The agency that has long been considered a global crown jewel in climate science and forecasting, has lost roughly 20% of its staff since January 2025.  The National Weather Service, which is housed within Noaa, has also taken a hit. Weather stations have had to delay data collection and cut operating hours, with hundreds of meteorological and other technical positions still vacant across its 122 forecast offices. … ”  Read more from The Guardian.

Congressman Tom McClintock discusses forest management, California water and the future of farming

“On a recent episode of the AgNet News Hour, U.S. Representative Tom McClintock, representing California’s 5th Congressional District, returned for Part 2 of his conversation with Nick Papagni. McClintock discussed federal forest management reforms, California’s water challenges and the economic pressures driving residents and businesses out of the state. The program also featured Kyle Kuechel of Syngenta AgriEdge, discussing crop protection developments and the upcoming winter produce season.  McClintock highlighted legislation he helped advance to streamline forest thinning projects in the Lake Tahoe Basin. According to McClintock, the changes reduced environmental review timelines from approximately five and a half years to just a few months, allowing more acreage to receive preventative forest treatments. … ”  Read more from AgNet West.

Congressmembers Carbajal, Padilla introduce bill to investigate toxic waste dumping off California coast

“New legislation introduced by Representative Salud Carbajal and Senator Alex Padilla is targeting a “forgotten history” off the Southern California coast: decades of dumping toxic industrial waste and pesticide pollution straight into the ocean.  This industrial waste — including the toxic pesticide DDT, banned in the United States in 1972 for its severe environmental and health risks — was disposed of in a constellation of ocean dump sites close to the coastline, particularly near Catalina Island and in the San Pedro Basin. The Ocean Protection and DDT Reduction Act would establish a “structured federal study to assess the damage to the local marine ecosystem and develop comprehensive solutions to clean up the waste,” according to Carbajal’s office in a press release.  It’s the next chapter in an alarming saga that started with UC Santa Barbara researcher David Valentine’s discovery of eerie barrels on the sea floor, surrounded by shocking amounts of DDT.  … ”  Read more from the Santa Barbara Independent.

Healthy Rivers and Landscapes: A healthier future for all of California

Nicole Montna Van Vleck, President and CEO, Montna Farms, writes, “Think about the last time you enjoyed a piece of sushi or took a bite of pizza. The rice wrapped around your favorite sushi roll, the tomato sauce, the cheese, perhaps a few peppers or olives sprinkled on top of that perfect slice. Chances are, you weren’t thinking about the water, the soil, the farms or the people that helped bring those ingredients to your table. And it is highly unlikely you were thinking about the salmon swimming through Northern California’s rivers, the sandhill cranes wading through winter-flooded rice fields or the Giant Garter snakes slipping between the tule brush. But all of these vegetables, grains, people and wildlife are much more interconnected than one might imagine.  California’s rivers and landscapes sustain an extraordinary range of life and activity. Water flowing through the Sacramento River Basin helps salmon and other native fish survive, nourishes wetlands along the Pacific Flyway, grows food for families across the country and provides reliable supplies for homes and businesses. The same lands that produce rice, fruits, nuts and vegetables also offer valuable habitat for wildlife.  As a third-generation rice farmer in the Sacramento Valley, I’ve seen firsthand how agriculture and nature can thrive together. For nearly a century, my family has grown rice in this region, and over those generations, we’ve learned that our fields can do more than produce food for people. This land can also provide important habitat for fish and wildlife. … ”  Continue reading this commentary.

Why Newsom’s Voluntary Agreements Won’t Work, Part 4: The Road Not Taken (Yet)

Gary Bobker, Program Director at Friends of the River, and Eric Buescher, Managing Attorney at San Francisco Baykeeper, writes, “As discussed in the first three parts of this series, the State Water Resources Control Board’s expected decision later this week to adopt the Voluntary Agreement (VA) Program as the central feature of the update of the Bay-Delta Water Quality Control Plan would willfully ignore three uncomfortable facts. The VA Program provides far too little water and habitat to be effective; it is highly unlikely to deliver on its stated purposes; and it was developed through an exclusionary, closed-door process that ignored the interests and expertise of a diverse array of affected California communities.  It doesn’t have to be this way. There was another path the Board could have taken – one that the next administration can still pursue to preserve the ecological treasures of our Central Valley rivers and the Bay-Delta estuary and manage our water resources sustainably with an eye toward a future impacted by climate change. … ”  Continue reading this commentary.

Two years after Klamath Dam removal, Governor Newsom and California’s actions threaten the river’s recovery

Regina Chichizola, Managing Director, Communities United for Water Protection, writes, “Early this month, we celebrated two years since the Klamath dams came out. Klamath dam removal is an amazing success story and example of how restoration pays off, this time to the tune of 20,000+ salmon going beyond where reservoirs used to fester. Unfortunately, while these salmon were heading upstream, one of the Klamath’s largest tributaries was going dry directly below them. These salmon also may not have made it without intervention on the Trinity River, where blocks of water are regularly released to stop a fish kill, thanks to another big win, the Lower Klamath long term plan.  Unfortunately, the Governor’s 1. push to divert more water from rivers, 3, manage river flows through voluntary agreements, and 2. Recent legislative vetoes threaten progress on the Klamath, which is dependent on the health of its tributaries, and the rights of Tribes. The State Water board not acting to protect our tributaries is not helping. … ”  Continue reading this commentary.

Baykeeper statement: CA State Water Board poised to adopt deeply flawed Bay-Delta Plan

“This week, the California State Water Resources Control Board (Board) is holding a series of adoption hearings on its revised Bay-Delta Water Quality Control Plan. The Plan is one of the single most important pieces of state water policy, regulating water quality and volume in the Sacramento River, Mokelumne River, and other tributaries as they flow into and through the Delta, to Suisun Marsh, and San Francisco Bay.  By law, the Board must adopt and regularly review the Bay-Delta Plan to ensure reasonable protection of fish, wildlife, fisheries, and other specified beneficial uses of water. The last significant update was more than 30 years ago. In that time, water quality and native fish populations have suffered major declines throughout the watershed, leaving the Bay’s ecosystem and communities that depend on healthy waterways in crisis. San Francisco Baykeeper, along with our Tribal, environmental, environmental justice, and fishing partners, have long advocated for the Board to meet its mandate with a protective, science-based update to the Plan. … ”  Continue reading this statement.

Minor coastal flooding expected this week around Humboldt Bay

Samoa Peninsula, Humboldt Bay. Photo by Don Barrett

“High astronomical tides this week are likely to result in minor coastal flooding along low-lying areas around the Humboldt Bay, according to the National Weather Service’s Eureka office.  “With the full moon, the highs are fairly high this week, but the difference is, with the warm ocean waters and other effects related to the El Niño, they’re running over a foot higher than the astronomical (tides) that you would sort of expect, and so they should be high enough today to cause some minor flooding in King Salmon and the Arcata Bottoms,” Meteorologist Matthew Kidwell told the Times-Standard Monday morning.  Kidwell said that tides would likely be slightly higher Tuesday, and will be roughly a foot higher than would otherwise be expected thanks to El Niño. He said that the minor flooding might be a “preview” of flooding later in the year should an unusually high king tide coincide with strong southerly winds — something that happened this year and resulted in record tides and flooding in King Salmon. … ”  Read more from the Eureka Times-Standard.

Cal Fire announces new heli-tank to strengthen Shelter Cove wildfire prevention

Plumas County receives six million dollars for wildfire recovery and resilience projects

“Plumas County received $6 million to support wildfire recovery efforts after the 2021 Dixie Fire. The money comes from a legal settlement with Pacific Gas and Electric Company and a PG&E program launched after the fire.  District Attorney David Hollister led the negotiations with PG&E. He emphasized the close relationship between Plumas County and the utility. Hollister focused on recovery and cooperation rather than penalties.  The settlement directs $1.5 million for public safety infrastructure in Greenville and Chester. Another $1.5 million goes to The Almanor Foundation for economic development and beautification in areas hit by the Dixie Fire. Sierra Buttes Trail Stewardship receives $1 million for rural development and recovery projects.  PG&E set aside an additional $2 million for a wildfire resilience fund. This money will remove dead trees and support other fire prevention efforts, working with the Plumas County Firesafe Council. … ”  Read more from Sierra News Daily.

2026 Yuba River salmon return numbers so far: Slower start, warmer water, and what it means for recovery

“At SYRCL, we track Chinook salmon returns closely because healthy populations of this keystone species are a key indicator of a thriving river ecosystem. Through SYRCL’s participation in the River Management Team (RMT), our staff receives monthly updates on the number of Chinook and steelhead adults utilizing the fish ladders at Daguerre Point Dam.  This information is collected using VAKI River Watcher camera systems installed in the North and South ladders, which snap a photo every time a fish swims past it.  2026 feels like a bit more of a return to previous years in terms of salmon numbers. Excluding the record setting 2025, we’re a little behind the average year-to-date passage number going back to 2018.  … ”  Read more from the South Yuba River Citizens League.

El Niño’s record-hot ocean waters driving coastal flooding in Southern California

“Unprecedented flooding is quickly becoming a fact of life in some Southern California coastal communities.  On Monday morning, high tide brought water pouring into business districts in Newport Beach and flooded part of Pacific Coast Highway in Sunset Beach. Sea water levels reached an all-time record high in San Pedro, topping 8 feet. Conditions are expected to get worse Tuesday.  What’s going on? After all, Southern California has endured El Niños before, as well as unusually high tides.  The difference, scientists say, comes to how hot the ocean waters have been. Hot water takes up more room than colder water, causing sea levels to rise.

Big Bear Lake’s $88.6M plan to stop flushing water down to the desert

“In 1884, a group of ranchers from Redlands rode up over 5,000 feet of elevation into the mountains to their north, where they built a rock dam to collect water for agriculture. It was an ambitious feat — at the time, the reservoir was the largest artificial lake in the world — that forever reshaped the green valley that once teemed with grizzly bears.  Big Bear is now in many ways defined by that lake, which provides a backdrop for the four-season tourist destination, from winter skiers and snowboarders to summer boaters and hikers.   But in recent years, the lake has been plagued by drought-fueled low water levels, followed by short recovery stints after heavy winter storms, making it a prime example of the climate change-fueled whiplash that’s being experienced across California. Meanwhile, the communities that have popped up around Big Bear Lake — filled with year-round residents who keep the businesses running and the community functioning — are staring down an uncertain water future. … ”  Read more from SF Gate.

Residents told me they feel this could have been avoided if the berm had been built higher.  Debbilyn Kovalik got the call from neighbors Monday morning that the sand berm in Mission Beach broke, sending water from the ocean rushing onto the sidewalk and into her home. When I walked inside with her, the water sloshed beneath our feet.  “It came up to here, and right in the sliding glass door, there’s water all the way through,” Kovalik said. … ”  Read more from Channel 10.

As Arizona joins Nevada’s Colorado River lawsuit, Imperial Valley farmers watch the water war intensify

Beautiful Landscape of Grand Canyon from Desert View Point with the Colorado River, Arizona.

“While lawyers for Arizona and Nevada square off against the federal government in a Las Vegas federal courtroom, Imperial Valley farmers are already calculating how much less water the All-American Canal will deliver to their fields.  Nevada sued the Interior Department and Bureau of Reclamation in late August, challenging the agency’s post-2026 operating guidelines for Lake Powell and Lake Mead. Last week Arizona moved to intervene as a plaintiff, arguing that the same plan — which locks in steep cuts for the Lower Basin states of Arizona, California, and Nevada — threatens its unique interests even more acutely.  In its motion, Arizona told the court its interests are “unique” and that it cannot entrust them to “another State that has sued to protect its own unique, state-specific interests.” The filing, submitted by the Arizona Department of Water Resources, seeks to join Nevada’s Administrative Procedure Act challenge to the Final Environmental Impact Statement, Record of Decision, and 2027-2028 guidelines that Reclamation issued in July and August. … ”  Read more from the Desert Review.

Arizona lawmaker challenges “manageable” water cut assessment

“Arizona Congressman Paul Gosar has invited U.S. Interior Secretary Doug Burgum to visit Arizona and take part in a flyover tour of the Colorado River system, arguing that the impacts of proposed federal water reductions are best understood by seeing conditions on the ground firsthand.  The October 23, 2026 invitation followed comments Burgum made during an interview with KOLD News 13, where he described Arizona’s anticipated water reductions as “completely manageable.”  In a letter dated October 23, 2026, Gosar disagreed with that assessment.  “Respectfully, what may look manageable in a Washington briefing room looks very different on the ground in Arizona,” Gosar said in a news release issued the same day. … ”  Read more from Western Water.

Did Arizona escalate a water war? Time will tell

Joanna Allhands writes, “When Arizona filed a motion to join Nevada’s Colorado River lawsuit, you could hear the collective gasp across the river basin.  Here comes the water war, the headlines screamed — the point where any hope for the river’s recovery ends.  But is that where we’re headed?  To a future of protecting our own interests, at great cost and with little to show for it in the end?  The next few weeks will be telling.  Many legal experts believe a judge will allow Arizona to get involved, though that’s not official yet.  Both states are asking a district court to throw out the federal government’s 10-year plan to manage the dwindling river.  They contend that the plan not only fails to adequately quantify the impacts of its deepest cuts, but that it also defies a century’s worth of law, court rulings and treaties.  For now, this is a lower court fight — and a rather limited one, at that. … ”  Read more from the Arizona Farm Bureau.

Arizona senator proposes new commission to address Colorado River water cuts

“A state lawmaker is proposing the creation of a new commission to address the water crisis.  State Senator Tim Dunn (R-LD25) announced the proposed commission in a Monday press release in which he also urged for the passage of HR 10420, legislation from Rep. Andy Biggs (R-AZ-05) that Dunn helped to craft.  Dunn said that he is drafting the legislation to create the Arizona Colorado River Commission.  Arizona is the only Lower Basin state in the Colorado River Basin without a state-level commission dedicated to handling the state’s water allotment. Dunn says a commission will strengthen the state’s position at the bargaining table when it comes to water rights.  The Colorado River Basin has reached historically low levels, forcing the federal government to proceed with water cuts across the seven western states relying on the supply. … ”  Read more from Arizona Free News.

Arizona’s San Simon Valley sinks nearly 7 feet as over 150 well applications pile up

“Arizona’s San Simon Valley is facing a new surge in groundwater drilling roughly a decade after residents first asked the state to slow agricultural expansion.  State records analyzed by AZCIR show 154 applications for high-capacity wells in the San Simon Valley since 2015. A report by the Arizona Department of Water Resources’ chief hydrologist said some ground above the already overdrawn aquifer has sunk by nearly seven feet.  After the jump in large-well filings, farmers in the area are once again seeking state protection for the San Simon sub-basin, according to AZCIR. State estimates put the sub-basin’s annual groundwater loss at about 50,000 acre-feet beyond what nature replaces — enough water to supply roughly 150,000 Arizona homes for a year.  Once ADWR acknowledged the petition in September, farmland that had gone without irrigation for five years became temporarily off-limits to new irrigation. The petition seeks an Irrigation Non-Expansion Area, or INA, which could permanently bar irrigation on newly developed farmland in the region. … ”  Read more from The Cool Down.

Phoenix water bills are some of the lowest in the U.S. Here’s what makes that possible

2161496477

“Even though Arizona’s water supplies are down, water bills in most cities have stayed relatively low. A new study found that water rates in Arizona have increased over the past decade, but many utilities in the Phoenix area have kept costs below the national median.  Of the 500 utilities included in the study, Phoenix’s water bills were the third cheapest, averaging $151.83 per year. The study was conducted by the nonprofit Food & Water Watch.  Other Valley cities — Tempe, Scottsdale and Chandler — landed in the bottom fifth of those rankings. Mesa and the private utilities EPCOR and Arizona Water Company were near the middle of the pack.  Gilbert and Tucson had the highest water bills of the dozen Arizona utilities included, with Gilbert’s $658.50 typical annual water bill topping that group and landing as the 121st most-expensive nationwide. … ”  Read more from KJZZ.

Heavy rain boosts Colorado River in Grand Canyon to highest water level of 2026

“After an epically dry winter and a tense summer for the Colorado River, the autumn has delivered a rare boost to one of its most iconic stretches.  In recent days, heavy rains pushed Colorado River flows through the Grand Canyon to their highest levels in years. The rains, which also caused flooding and destruction in communities throughout the Four Corners region, provided a crucial slug of water to the Grand Canyon’s unique ecosystems.  River scientists are still gathering precise information about the exact volume of water surging through the river, but experts estimate flows reached at least 21,000 cubic feet per second. According to the U.S. Geological Survey’s measuring station above Diamond Creek, that marks the highest rate of flow since April 2023, when water managers deliberately sent a massive, sudden burst of water through the canyon. … ”  Read more from KJZZ.

Utah’s urban residents rely on Colorado River water. Here’s how it gets there.

“A massive concrete wall rises 200-feet above a trickling creek where Duchesne County’s tan plateaus transform into green forested slopes. Behind it, snowmelt from the Uinta Mountains pools into a dark blue reservoir, water lapping on red rock shores.  At just over 8,000 feet in elevation, the Upper Stillwater Dam marks the start of the Central Utah Project, which conveys water from the Colorado River Basin to the Great Basin where around 90% of Utahns live.  “It’s the crown jewel of the Central Utah Project,” Dylan Dastrup, Stillwater area manager with the Central Utah Water Conservancy District, said as he pointed to the grey wall. The district maintains and operates the project facilities, which are owned by the federal government.  From Upper Stillwater, a drop of water, which otherwise would flow to the Duchesne River, then the Green River before meeting the Colorado, begins a journey west. It does that thanks to decades of engineering and over 100 miles of tunnels, pipelines and diversions that carry the water to the state’s biggest cities. After a pit stop at Strawberry Reservoir, it cuts through the mountains and flows into pipelines that deliver water to farms, lawns and taps across the Wasatch Front.  Some of that water even makes it as far as the Salt Lake City International Airport. … ”  Read more from The Water Desk.

Heavy rain in southeast Utah has prompted a rise in Lake Powell’s water level. Here’s how much.

“Heavy rain that caused flooding last week in the Four Corners area of Utah, Colorado and New Mexico has had what water experts say is a beneficial side effect: A marked rise in the water level of Lake Powell.  Saturday’s daily measurement of Lake Powell’s level was at 3,526.1 feet above sea level — which is 1.1 feet above the level the day before, and 7.1 feet above where the lake was two weeks ago, according to the Lake Powell Water Database. It’s also 9.5 feet above the lake’s lowest point on Sept. 15.  “That’s phenomenal this time of year,” Gene Shawcroft, chair of the Colorado River Authority of Utah, said Sunday. … ”  Read more from the Salt Lake Tribune.

Going up: Water level at Lake Powell rises after recent rainstorms

“Lake Powell is experiencing a sudden reversal in its water level fortunes, thanks to rainstorms that have pounded the region in the past week.  The water level at the United States’ second-largest reservoir has risen to 3,529 feet, about 10 feet above its record low of 3,519 feet above sea level, which was recorded in August, the National Weather Service office in Salt Lake City reported Sunday on X.  The lake’s “water levels continue to rise from all of the heavy rain across the Four Corners,” the weather service said. “A lot more water (is) moving towards Lake Powell as river flows remain very high.” The lake is mainly fed by the Colorado and San Juan rivers, according to lakepowellwaterlevel.com.  The Four Corners region — the juncture of Utah, Arizona, Colorado and New Mexico — has been hit hard by heavy rains during the past several days. Severe flooding has led to evacuations and water rescues. … ”  Read more from the Las Vegas Review-Journal.

Colorado won’t launch water-conservation program in 2027 without guarantee from feds

“Colorado water managers say a state-run conservation program planned for 2027 is in jeopardy as they wait on an agreement with federal officials.  Before they open the application period for a new conservation program, state officials want assurance from the U.S. Bureau of Reclamation that conserved water they store in Lake Powell won’t just be released downstream for Lower Basin use.  In September, the state water board approved the application review process and criteria for what state officials are calling Colorado’s near-term contribution program for 2027. The program aims to use nearly $100 million in funding from Reclamation to pay water users in the Upper Basin states (Colorado, New Mexico, Utah and Wyoming) to voluntarily cut back.  But that approval depends upon whether Colorado can get credit for and have control over the stored water. State officials said repeatedly at an Oct. 21 meeting with the Colorado River Water Conservation District that they need assurance in writing from Reclamation that the pool of stored water must be “operationally neutral” — meaning it would not be factored into reservoir releases or used by the Lower Basin — before they move forward with a state-run program. … ”  Read more from Aspen Journalism.

What officials know so far about major flood impacts in southwestern Colorado

“The floodwaters are beginning to recede in parts of southwestern Colorado, but the dangers haven’t washed away. Crews are just beginning to assess the damage from days of heavy rain and severe flooding, while officials warn of uncertain road conditions, potentially unsafe drinking water and overwhelmed sewage systems.  In Rio Grande County, one of at least a dozen counties hit by the flooding, some sheriff’s deputies are being pulled off helping those impacted by the flooding for search and rescue efforts in the high country to help hunters stuck in the mud.  “We don’t know the condition of all the roads. We have hundreds and hundreds of miles out there,” Patrick Moran, a district ranger with the Forest Service, told about 130 residents inside a South Fork church hall Monday night, with another 200 tuned in online.  “We have people getting stuck and needing rescue and it is pulling resources out from the local effort here because the sheriff and her team are having to break off to assist with that,” he said. … ”  Read more from the Colorado Sun.
