Beginning August 28, the Utah Division of Wildlife Resources will be adding rotenone to several lakes and streams in the Eastern Uinta Mountains aimed at helping eliminate invasive species that threaten the populations of Colorado River Cutthroat trout.

Bear Lake, on the Idaho-Utah border, is sometimes referred to as the “Caribbean of the Rockies” due to its turquoise-blue waters. Locally famous for its Raspberry Festival, boating opportunities, and fishing, Bear Lake is also home to several species of fish found nowhere else in the world. In a recent study published in the journal Freshwater Biology, researchers from Utah State University have determined that falling water levels are negatively impacting these fishes.

Here on the campus of Utah State University, I’ve got this book sitting on my desk. It’s green, hardcovered, and wider than it is long. It has some of the best and most detailed paintings of fish in it that I’ve ever seen- and as a fisheries grad student, I’ve seen a lot of books on fish.

Before the widespread introduction of non-native fish species like Rainbow and Brown Trout, Colorado River Cutthroat Trout occupied large portions of the Yampa, White, Colorado, and San Juan river basins. Today, this black-spotted, yellow and red fish has been reduced to only 14 percent of its historical range.

In the 1970s, many feared Utah’s native fish, the Bonneville Cutthroat Trout, was extinct.

A search began and in a short time, with a sigh of relief, state managers were able to report the Bonneville cutthroat trout was still in Utah’s rivers and streams, but the sub-species was imperiled and had experienced dramatic reductions in abundance and distribution rangewide.
