According to the U.S. Department of Agriculture (USDA) National Water and Climate Center’s snowpack report, the Wolf Creek summit at 11,000 feet of elevation, had 5.7 inches of snow water equivalent as of noon on Tuesday, Nov. 22. The Wolf Creek summit is at 88 percent of the Nov. 22 snowpack median. The San Miguel, Dolores, Animas and San Juan river basins were at 93 percent of the Nov. 22 median.

River report

Stream flow for the San Juan River on Nov. 22 at approximately 11 a.m. was 75.1 cubic feet per second (cfs), according to the U.S. Geological National Water Dashboard, These numbers are down from a nighttime peak of 108 cfs at 10:15 p.m. on Nov. 21. This reading is also slightly down from 84.5 cfs at 11 a.m. on Nov. 15.

At a Nov. 15 joint work session, the boards of the Pagosa Area Water and Sanitation District (PAWSD) and the San Juan Water Conser- vancy District (SJWCD) met to discuss the terms of a lease exten- sion agreement that would give the Weber family another year to operate the gravel pit at the Run- ning Iron Ranch. Both PAWSD and SJWCD are the technical landlords of the property, which is the same site being proposed to house a reservoir commonly referred to as the San Juan River Headwaters Project (SJRHP) or Dry Gulch.

In April, PAWSD originally decided to not extend the Webers’ lease, citing reasons like pricing, the benefit to PAWSD customers and the reclamation timeline of the site. However, in September, the board reconsidered after the Webers offered new lease exten- sion terms. In the new terms, Andy and Kathy Weber proposed that the lease be extended for one year at a cost of $48,137.78 with the po- tential to renegotiate or extend the lease at the end of the year. The lease terms also include that the Webers would complete structural restoration on the current gravel pit site within the year.

San Juan Basin Public Health offering free well testing for #PFAS chemicals — The #PagosaSprings Sun

San Juan Basin Public Health (SJBPH) has received a grant from the Colorado Department of Public Health and Environment to address contaminants in drinking water. The funding will be used to provide free testing for perfluoroalkyl and polyfluoroalkyl substances (PFAS), which is a broad group of manmade chemicals in industry and consumer products sometimes known as “forever chemicals” because they do not easily break down in the environment or the human body…

La Plata County and Archuleta County residents can now have their private wells sampled and tested for PFAS chemicals at no cost. The program is targeting areas in the counties close to fa- cilities where PFAS chemicals are known to be used or stored, but all well owners in both counties are encouraged to have their wells tested. Facilities that may have stored or used PFAS chemicals in- clude airports, landfills and some fire stations. If you receive water from a municipality, water district or shared delivery system, contact your water provider for PFAS infor- mation. Several local public water providers have already tested their systems for PFAS contamination. SJBPH Environmental Health staff will be available to discuss test results, which will be processed by a certified independent labora- tory and can take up to 45 days to receive. Staff will assist well owners with determining next steps based on the test results. To have your well water tested, please contact us at eh@sjbpublichealth.org or (970) 335-2060…

There are several education events planned to help share in- formation on PFAS chemicals and testing options. Join us from 5:30 to 6:30 p.m., Thursday, Dec. 8, at the Durango Public Library, 1900 E. Third Ave., Durango. Additional education events in Archuleta and La Plata counties will be an- nounced in the weeks to come.

Saving the #RioGrande Cutthroat Trout: Beavers show the way — @AlmosaCitizen

THE Rio Grande cutthroat trout is the Rio Grande National Forest’s only native trout. It needs help. Biologists from Colorado Parks and Wildlife and Rio Grande National Forest are trying to bring the cutthroat back to its full glory, but they need help, too. So who do the humans look to for help?

Easy answer: Beavers. 

Jason Remshardt, wildlife and fisheries program manager for the Rio Grande National Forest, recently gave a presentation on the Rio Grande cutthroat trout. He is the only fish biologist in the RGNF. He talked about the effort to create and conserve habitat for the cutthroat, and how the answer might just come from nature’s finest engineers. 

The Rio Grande cutthroat trout used to exist in just about every part of the Rio Grande basin, but due to a wide range of circumstances, these fish only occupy a fraction of the area they used to. Part of conservation and successful reintroduction is habitat restoration. Right now, the experts are looking at nature’s experts. These projects are imitating “what the beaver dams are doing,” said Remshardt. 

These “Beaver Dam Analogues” or “Temporary Wood Grade Structures,” or TWGS, (pronounced like twigs), are designed to help back up water and create a lively wetland habitat that encourages healthy biodiversity not just for the cutthroat, but the entire ecosystem. 

“Beaver Dam Analogues” or “Temporary Wood Grade Structures,” or TWGS, (pronounced like twigs), are designed to help back up water and create a lively wetland habitat that encourages healthy biodiversity not just for the cutthroat, but the entire ecosystem. They are being employed in what’s called “Process-Based Restoration.” These man-made structures are relatively easy and straightforward to make. They are built with natural resources such as wooden posts, willow branches, aspen branches, and rocks. Though they are simple to create, Remshardt said “we’re not as good at building them” as the beavers. Photo courtesy Rio Grande Headwaters Restoration Project

“It’s a technique that’s become increasingly popular across the western U.S. within the last few years,” said Connor Born, project manager for the Rio Grande Headwaters Restoration Project. 

The man-made structures can help to create a more complex habitat that encourages a healthier fish population. Born says that this can mean “deeper pools that serve as low-flow refuge and slower moving water for younger fish. The structures can also benefit surrounding vegetation, provide fire breaks, increase stream shading, and grazing forage.” 

Cutthroat trout populations often live in smaller streams that don’t have much water. According to Born, “The structures can help attenuate water in these smaller streams to provide more consistent flow and temperature during periods of drought.”

Cat Creek near La Jara Reservoir once had populations of the cutthroat and beavers. For unclear reasons, the beavers left that area. Their departure, Born says, “paired with prolonged drought conditions, caused flows to become much more intermittent, eventually leading to the suspected die-off” of the cutthroat trout population there. 

So far, the groups undertaking this project have implemented 10 of these structures in the Rio Grande National Forest. Remshardt noted that “if they last for a few years, that’s great. If the beavers take them over, that’s great. If they disappear, then you haven’t lost that much. You’ve just lost like half a day’s work.” 

According to Born, the first 10 structures are in the headwaters of Saguache Creek in Saguache Park. There are 12 more ready for construction in the coming year that will be built along Big Springs Creek, a cutthroat stream near Saguache.

Born said that the restoration structures can function without beavers, but the organizations are hoping to find places where the two can combine forces. 

Beavers in the national forest are alive and thriving. Remshardt says that the RGNF is happy with current populations, but there is room for expansion and improvement. With that, the benefits of beaver dams create healthy, expansive wetlands. Beaver dams and habitats also make great fire breaks

These animals, however, are considered a nuisance species to certain areas of the Valley. Beavers can be troublesome to infrastructure like irrigation canals and roads. 

“There’s this stark contrast of existing as a pest species on the Valley floor while being highly beneficial up in the headwaters. The logical solution,” Born said, “is an efficient, legal, and humane way to translocate them to areas where their engineering is more appreciated and doesn’t impact infrastructure.”

Relocating the beavers pairs well with the restoration efforts. Born said that the structures may encourage beavers to stay in areas that “have habitat that would otherwise be too degraded.”

Remshardt says there’s plenty of space to relocate any problematic, or displaced wood-chopping rodents. 

“We’re ready to take them and we have places all over the forest to take them. Plenty of places we can put them,” Remshardt said. 

Identifying where beavers are and where beavers aren’t is a part of the job that requires a lot of work from a lot of people. Software like iNaturalist allows anyone to report animal sightings and tracks to help in identification. These reports can help biologists like Remshardt identify populations and locations to help further studies and surveys. 

Helping the beavers help us really boils down to, Remshardt said, the fact that “beavers are the best at doing their own work.”

Surveys and History

The largest effort for studying these fish are surveys. Remshardt said they conduct surveys on every population of RGCT about every five years. These surveys cover at least 40 streams in the national forest and take a large number of people to conduct. The surveys gather the number of fish and their sizes, take genetic samples, and conduct health surveys. 

Most of the streams and lakes are easy to access, but the Rio Grande Cutthroat Trout lives in the alpine, too. Remshardt said almost every drainage and lake in the Sangre de Cristo mountain range has cutthroat populations. So, in order to keep these high mountain lakes stocked and healthy, they conduct High Mountain Lake Airplane Stocking. A video from CPW shows just how these operations are done. 

Conservation of the cutthroat, Remshardt said, remains the most intensive and expensive project. Ongoing research for more cutthroat introductions to expand them into their historic ranges is an ongoing and expansive effort. Currently, an effort to successfully reintroduce the cutthroat to the Sand Creek drainages at the Great Sand Dunes National Park is taking place. The project first started in 2005.

blog post by Trout Unlimited’s Rio Grande Basin project manager Kevin Terry breaks down the history of this project. You can also read the USGS’s in-depth report on this effort here.

CPW estimates that the RGCT occupies just 12 percent of its native habitat. Biologists estimate that 127 “conservation populations” exist in Colorado and New Mexico. The cutthroats’ range has seen a dramatic decrease over the last 150 years. Some of the factors that have led to this decline are habitat changes, climate change, drought, water quality, hybridization with non-native Rainbow Trout and other cutthroat trout species, as well as aggressive competition from Brown and Brook trout. 

Evidence suggests that the cutthroat trout thrived in healthy populations in Lake Alamosa, a lake that existed for over three million years. 

The Rio Grande Headwaters Restoration Project, US Forest Service, Colorado Parks and Wildlife, and Trout Unlimited “are hoping to identify both at-risk RGCT populations and future locations for reintroduction and enhance the habitat using these restoration techniques,” Born said.
