Friends of Our Watershed is a new segment of our water program newsletter where we introduce you to important species that share our local watershed.
Caring for Cutthroats
Which of our friends has a beautiful greenish-blue back, silvery sides, abundant spots, and signature orange and red slashes near their lower jaw? You guessed it—the cutthroat trout! These colorful salmonoids are native to Colorado and are typically found at elevations of over 7,000 feet. Unfortunately, our most beautiful native ﬁsh is now one of the most imperiled.
Cutthroat have long been impacted by settlement on the Western Slope. In the mid-1800s, discovery of gold in our headwaters led to some of the ﬁrst issues with habitat destruction. Today, dams, road creation, logging, mining, water diversions and withdrawals, introduction of other ﬁsh species, hybridization, and climate change are all contributing factors to the decline of our native friends. Although the cutthroat is still not nationally listed as a threatened or endangered species, the State of Colorado manages Colorado Cutthroat Trout as a sensitive species in recognition of the challenges facing these ﬁsh.
At HCCA, we strive to help protect our sleek and ﬁshy friends in the Gunnison River Basin. Last year, we joined forces with Western Resource Advocates to defend a contested instream ﬂow appropriation for Schaefer Creek, in the North Fork of Gunnison County. Schaefer Creek has a population of 96% genetically pure cutthroat trout, making it of “greatest conservation signiﬁcance” to the U.S. Forest Service. An instream ﬂow protection for Schaefer Creek has been ofﬁcially approved by the State, meaning that the creek and its invaluable native cutthroat trout population will be permanently protected against future diversions!
This year we are working toward additional instream ﬂow protections on Brush Creek and Coal Creek in partnership with American Rivers. Brush Creek also houses an incredible cutthroat trout ﬁshery and is a favorite ﬁshing and recreation destination for Crested Butte locals and visitors alike. The proposed instream ﬂow protection for Brush Creek will ensure that spring, summer, and fall ﬂows can support these breeding populations of the cutthroats for generations to come. We spent the majority of the summer and fall soliciting community support for our proposal, and we can’t wait to see the outcome in January, 2017.
Beaver Fever (Part 1/2)
Leave it to the beavers. Among the largest living rodents in the world, these web-footed creatures with thick fur and scale-covered tails are a keystone species in our local watershed. As a keystone species, many other species rely and depend on beavers. When beaver are removed from an ecosystem, that ecosystem may change drastically. Eighty-five percent of all wildlife depends on a beaver or beaver-created habitat at some point in their lives. Beaver use strong and powerful teeth to fell trees to construct their homes and dams.These lodges and dams are woven together with sticks, grasses, and moss then plastered with mud. Beavers are pretty incredible architects!
Beaver dams can impact local waterways. Dams can cause flooding and may alter the flow of a river. These industrious fellas may even plug up a culvert. At the same time, beaver dams slow down water velocity, help prevent soil erosion, and can help to reduce sedimentation while improving water quality. Beaver ponds create habitat for endangered wildlife and plants and promote overall biodiversity.
Beaver Deceivers (Part 2/2)
In our previous Friends of our Watershed we learned all about beavers. Despite the numerous services and benefits that this keystone species brings to our local ecosystem, many landowners find them to be a nuisance. Until recently, in many states you could simply purchase a permit to shoot, trap, or drown beavers indiscriminately. Within one century, our country’s beaver population has dropped from 60 million to 100,000.
There are many different ways that humans and beavers can coexist. Beaver dams that lead to flooding are typically the largest nuisance for most homeowners and often occur when beavers dam a culvert. Luckily, there are many different ways that these issues can be resolved without shooting, trapping, or drowning our furry friends. Allowing beavers to remain in an area while solving the specific problem (for example, a felled tree or flooded yard) can also preserve the benefits our watersheds garner from our beaver friends.
One interesting tool that we would like to highlight is a Beaver Deceiver, which is a trapezoidal shaped culvert fence that was invented in the 1990s. You can use one of these fences to block the culvert, and the fence forces the beavers to build their dam in a direction away from the culvert. By using this type of flow device, you can sustain the many beneficial qualities that beavers bring to our ecosystems, while reducing the impacts of flooding with an inexpensive technology that requires little maintenance.
