From email from Scott Hummer at the Colorado Division of Water Resources:
Bear River Water Users,
Effective at 9:00 am, tomorrow, May 24, 2020: The Bear River will go on Call and under Administration.
The Swing Right (most junior right partially in priority) will be Yamcolo Reservoir, Admin #41329.00000…the dry up point is the Nickell Ditch.
All current diversions “junior” to Admin #41329.00000…Must be curtailed.
Water will be released from Yamcolo tomorrow morning in order to meet the demand by Senior rights at the bottom end of the system.
There is currently not a need for any water users Senior to Yamcolo Reservoir to place an order for the delivery of contracted/stored water.
The Call situation will be subject to change dependent upon a variety of circumstances, I’ll keep you posted as to any changes in a timely manner.
UYWCD is currently planning to calibrate the new measuring equipment in the Five Pine Ditch on Tuesday the 26th…and there may be some fluctuation in river flows during the task.
Please contact me with any further questions or comments.
A dam failure and a flood, in the middle of a global pandemic: it’s a worst-case scenario.
A dam failed in Michigan [May 19, 2020], forcing thousands of residents to evacuate their homes. The Edenville Dam, which failed, and the Sanford Dam, which was compromised, are on the Tittabawassee River, a tributary of the Saginaw River. The failures followed days of heavy rainfall and sent floodwaters into downstream communities. Residents of Edenville, Midland and Sanford were evacuated.
A dam failure and a flood, in the middle of a global pandemic: it’s a worst-case scenario. The immediate focus needs to be protecting public health and safety. Governor Whitmer encouraged people to seek shelter with friends or relatives, and to take precautions to prevent the spread of coronavirus.
How did this happen?
Why did these particular dams fail? Was it because of heavy rains? Climate change? Faulty, aging infrastructure? Lack of action by the dam owner? Right now, we know the following:
The Edenville Dam was plagued by concerns and safety violations. The Federal Energy Regulatory Commission revoked its hydropower license in 2018 due to concerns that the dam could not withstand a significant flood. FERC flagged problems for the dam’s owner starting in 1999.
Climate change is bringing more severe and frequent flooding at a time when our nation’s infrastructure is aging and outdated.
The American Society of Civil Engineers has repeatedly given our nation’s dams a grade of D in their “Report Card for America’s Infrastructure” – citing age, downstream development, dam abandonment and lack of funding for dam safety programs. More dams will fail, endangering people and property, unless we act to repair essential infrastructure and remove dams that no longer make sense. The Association of State Dam Safety Officials estimates there are more than 2,000 high-hazard dams nationwide in deficient condition.
The dam failure in Michigan isn’t the first “wake up call” when it comes to the need to address aging infrastructure. Dozens of dams failed in the Carolinas five years ago; thousands of residents were evacuated due to the partial failure of nation’s tallest dam, Oroville Dam on the Feather River, three years ago; and last year the Spencer Dam failed in Nebraska forcing evacuations. These disasters aren’t specific to one region, they are impacting communities nationwide.
While we’re still learning about the specifics of this disaster which is still unfolding in Michigan, the following three actions are necessary to protect communities in the future:
Increase, don’t decrease, public safety and environmental safeguards – The safety of federally licensed hydropower dams is overseen by FERC. While FERC revoked the dam’s license in 2018 due to safety concerns, that clearly was not enough to prevent this week’s catastrophe. Moreover, on the same day the dams failed, President Trump signed a new executive order to roll back more regulations under the guise of restarting the economy. Further gutting the regulations that safeguard human lives and safety and protect the environment is the wrong way to produce a sustainable economic recovery.
Strengthen evaluation and enforcement – Michigan has a working dam safety program. Even so, state dam safety offices are historically underfunded with a limited number of staff responsible for inspecting thousands of dams. We must improve these efforts by making it the responsibility of dam owners to inspect and maintain their dams; requiring more frequent, detailed inspections of deficient dams and increasing penalties for unsafe dams and violations; and, requiring dam owners to ensure that funds are available to repair or remove dams in the event they can’t or won’t meet safety standards. As communities continue to grow and development expands, many dams may also be misclassified as infrastructure and development increases downstream.
Increase funding for dam removal and water infrastructure – Dam removal can be the best way to address a dam that poses a safety risk. There are tens of thousands of dams across the country that no longer serve the purpose they were built to provide and whose removal could eliminate the cost and liability associated with owning a dam. Unless they are well maintained, their condition only gets worse every year. The most cost-effective and permanent way to deal with obsolete, unsafe dams is to remove them.
Healthy rivers are the lifeblood of our communities and our environment, and we depend on essential infrastructure to provide water, power and other services. It’s time to prioritize river protection, and investment in smart infrastructure. Our communities, our economy and our lives depend on it.
FromInside Climate News (James Bruggers, David Hasemyer and Bob Berwyn):
The flooding disaster in Michigan this week emphasized, in stark reality, the warnings by scientists that climate change is causing heavier and more frequent rainstorms in many parts of the country, including the upper Midwest.
Old dams are at risk of failing under the pressure of torrential rains. And in the hours leading up to Tuesday’s failure of two dams about 150 miles northwest of Detroit, about eight inches of rain fell in the watersheds that drain into the Tittabawassee River.
First the 1920s-vintage Edenville dam broke, sending water rushing down the river to Sanford Lake. That deluge overtopped and breached the Sanford Lake dam, officials said, prompting the evacuation of 11,000 people, the flooding of the city of Midland and the inundation of its sprawling Dow Chemical Company complex.
At the Dow plant, the water flooded a containment pond, prompting environmentalists to fear that a toxic brew could spill into the river. That could set back years of downriver cleanup of the pollution from more than a century of chemical production at Dow’s chemical manufacturing plant, they said.
In a statement on its Twitter feed, the company said the flooding at the plant posed no threat to the community. “The material from the brine pond does not create any risk to residents or the environment,” the statement said.
Scientists, environmental advocates, and dam safety experts said that the heavy rains were an example of the extreme weather that scientists have linked to climate change.
“We are seeing more rain, and more precipitation in general,” said Richard B. Rood, a professor of meteorology at the University of Michigan’s College of Engineering. “The other thing we have been seeing is individual events that are more extreme and more precipitation in general.”
He added, “That is especially true the last half-decade and is a trend that has been emerging for the last 50 years.”
Federal officials have issued preliminary permits for two hydro-storage proposals on the Little Colorado River. The projects would include four dams and four reservoirs east of Grand Canyon National Park. KNAU’s Ryan Heinsius reports.
The Federal Energy Regulatory Commission’s approval doesn’t allow the Phoenix-based company Pumped Hydro Storage to enter any lands or create ground disturbance. But it does let the company conduct feasibility studies for the combined 4,700-megawatt projects that would include dams up to 240 feet high across the Little Colorado River on the Navajo Nation…
Groups like the Grand Canyon Trust, Sierra Club and the Center for Biological Diversity say it would destroy the Little Colorado’s ecosystem and the habitat of the endangered humpback chub. The U.S. Interior Department has also objected.
The Colorado Office of Economic Development and International Trade announced a total of $7.3 million in Advanced Industries Accelerator grants Thursday to companies and educational institutions around the state, including in Northern Colorado and the Boulder Valley…

Here’s the release from Colorado Parks and Wildlife (Joe Lewandowski):
After nearly a two-year wait, Colorado Parks and Wildlife hatchery staff and biologists in Durango have spawned a new lineage of Colorado River cutthroat trout that were rescued from a remote stream during the 416 Fire in 2018.
This marks a major milestone for CPW’s on-going species conservation work in Colorado, and the result of decades of work by dedicated biologists, researchers and field staff.
Fertilized eggs of the San Juan cutthroats will hatch by mid-summer; some of the fingerlings will be placed in back-country streams in the southwest area of the state and others will be held at the Durango hatchery to start a sustainable brood stock. Now, the hatchery staff and biologists will continue the long-term effort to restore these native trout to their home waters.
“I’m thrilled that we’ve gotten a spawn from these fish, it’s been a long process and we’ve got a lot more work to do,” said Jim White, aquatic biologist for CPW in Durango.
The story of these fish that hold a unique genetic marker goes back nearly 150 years and includes some serious biological detective work. Since the 1970s, CPW aquatic biologists have searched back-country streams looking for isolated populations of cutthroats — Colorado’s native trout. In southwest Colorado in the 1980s and 1990s, biologists found cutthroat trout that were suspected to have unique characteristics in eight small streams. Back then, however, technology to analyze genetics fully was still being developed. The biologists kept their eyes on the fish and made sure non-native trout were not stocked nearby.
In 2012, researchers from the University of Colorado went to the Smithsonian National Museum of Natural History looking for preserved specimens of cutthroat trout that had been collected in Colorado. Two of the specimens they found were taken from the San Juan River near Pagosa Springs in 1874.
An analysis showed that the fish had genetic “fingerprints” specific to the San Juan River Basin. CPW researchers then began a similar analysis of the cutthroats they’d found in southwest Colorado. By this time, genetic-analysis technology had advanced and in early 2018 scientists confirmed that the marker in the museum specimens matched the cutthroat trout recently found in the wild.
Biologists and hatchery staff then made a plan to start propagating the fish. The 416 Fire helped push the project along.
When the fire started north of Durango, biologists worried that ash and sediment run-off could kill the cutthroats in the remote streams. So CPW worked with the San Juan National Forest to go into the area to capture the wild trout and bring them to a special isolation hatchery in Durango. Only 54 cutthroat were recovered from the fire area.
White and Durango Hatchery Manager Toby Mourning have been concerned because the fish did not produce any spawn last year and some of the fish died. But the turnaround this year is a major milestone for the restoration effort.
“We’re not getting a lot of eggs, but enough to provide some for a limited amount of stocking and some to start a captive population that will be sustainable,” Mourning said.
In order to protect the fish, CPW is not providing details on stream locations. Biologists hope, however, that in a few years anglers will be able to find this unique cutthroat trout in the wild.
White explained that the work on this native is a significant conservation effort. In 2018, after the genetics of the fish were confirmed, he said: “We always ask ourselves, ‘What if we could go back to the days before mining, pioneer settlement and wide-spread non-native fish stocking to see what we had here? Careful work over the years by biologists, finding those old specimens in the museum and the genetic testing gave us the chance, essentially, to go back in time. Now we have the opportunity to bring this native trout back to southwest Colorado.”
Here’s the release from the USGS. Click through for all the links and a great animation of one reach of the stream below the dam failures:
U.S. Geological Survey field crews are measuring record flooding on the Tittabawassee River in Midland, Michigan, following a heavy rainfall event.
The USGS Tittabawassee River in Midland streamgage measured record water levels, called river stage, at about 35 feet on Wednesday. This level is the highest ever recorded during the streamgage’s 84 years of record, and exceeds the previous highest stage by about two feet. Water levels are beginning to recede as of this morning, and two two-person USGS crews are measuring streamflow in Grayling and Lansing. They also installed a rapid-deployment gage to provide backup to the permanent streamgage at the Midland site.
Strong storms passed through parts of the Midwest starting last Thursday, causing minor-to-major flooding in some lower Michigan locations. On Tuesday, May 19, two large dams on the Tittabawssee River failed in succession, causing two lakes upstream of Midland to drain. The USGS crews will continue to monitor water levels and streamflow as flooding continues.
Elsewhere in Michigan, the USGS Rifle River streamgage near Sterling crested on Tuesday with a record streamflow of 7,460 cubic feet per second. There are currently four additional single-person crews measuring streams throughout lower Michigan, and they will continue to monitor flooding for at least another day.
Information collected by the USGS during flooding is critical for resource managers and emergency responders to help protect life and property. The USGS coordinates efforts with the National Weather Service, US Army Corps of Engineers, Bureau of Reclamation and many local and state partners.
There are about 200 streamgages in Michigan that measure water levels, streamflow and rainfall. When flooding occurs, USGS crews make numerous streamflow measurements to verify the data USGS provides to federal, tribal, state and local agencies, as well as to the public.
For more than 125 years, the USGS has monitored flow in selected streams and rivers across the U.S. The information is routinely used for water supply and management, monitoring floods and droughts, bridge and road design, determination of flood risk and for many recreational activities.

On behalf of the State of Colorado, Attorney General Phil Weiser today filed a lawsuit in federal district court in Denver to protect Colorado’s streams and wetlands from a dangerous federal rule that would leave them vulnerable to pollution under the Clean Water Act.
By radically changing how the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers define “waters of the United States” that are protected under the Clean Water Act, the new 2020 rule will leave a substantial portion of Colorado’s streams and wetlands without federal protection and jeopardize the integrity and quality of Colorado’s waters.
“The federal government’s new definition of ‘waters of the United States’ violates the Clean Water Act, contravenes controlling U.S. Supreme Court precedent, and ignores sound science,” Weiser said. “This illegal action shirks the federal government’s responsibility to implement this law and thrusts on Colorado the responsibility of protecting water quality with limited warning and with no support to do so. We are bringing this lawsuit to stop this new rule and reckless action from taking effect.”
The Clean Water Act protects U.S. streams, wetlands, and rivers from pollution. Previously, under Supreme Court precedent, the rule included ephemeral streams—streams that run because of melting snow or precipitation—and wetlands that aren’t connected on the surface to larger bodies of water.
“We need to challenge this action to avoid a bigger problem for our economy at a time when our state is already hurting from COVID-19. Some flood control, stormwater erosion, transportation, and other important projects may not be able to move forward because the new rule takes away the permitting path needed to ensure environmental protection and project development. That’s a problem that we need to fix,” said John Putnam, Environmental Programs Director, Colorado Department of Public Health and Environment.
The new 2020 rule does not include many ephemeral streams or wetlands without a surface connection. The lawsuit states that the new, narrower definition of the types of water protected under the Clean Water Act eliminates federal jurisdiction over a significant number of Colorado’s tributaries, adjacent waters, and wetlands that affect downstream waters, without providing any rational basis for the rule. This leaves Colorado’s snowmelt streams and wetlands vulnerable to pollution, which would negatively impact our state’s agriculture and outdoor recreation economy.
Through the lawsuit, Colorado is asking the court to maintain the definition in place since the 1980s and to stop the new, unlawful rule from going into effect. In so doing, Colorado is following up on its comment to the agencies, which praised earlier 2008 guidance as legally sound and grounded in science. Maintaining the status quo will also protect important agriculture exemptions, respect state authority to administer water rights, and provide the appropriate level of federal partnership.
