Rocky Mountain National Park Fishing Overview

Fishing is a popular activity in Rocky Mountain National Park, where efforts are made to maintain a balance between fishing and preserving the natural aquatic environment. The park has been actively working since the 1970s to restore native cutthroat trout populations, which have now been successfully reintroduced.

In addition to cutthroat trout, the park is home to brown, brook, rainbow, Colorado River, and Yellowstone trout, as well as suckers and sculpin. However, many of the high altitude lakes in Rocky Mountain National Park do not have self-sustaining fish populations due to the cold water temperatures and lack of suitable spawning grounds.

Rocky Mountain National Park fishing is an enjoyable activity for people of all ages, but it is important to be aware of and follow the rules and regulations set by the park. Before embarking on a fishing trip in Rocky Mountain National Park, it is essential to familiarize yourself with which waters are open for fishing and which are off-limits to ensure that you are fishing responsibly and in accordance with the park’s guidelines.

Rocky Mountain National Park Guidelines

Aquatic threats are commonly found in lower elevation areas, so it is recommended to start your cleaning process at the top of drainage and move downstream to prevent the spread of these threats during your Rocky Mountain National Park fishing adventures. It is crucial not to transfer fish between different bodies of water as this can lead to the spread of harmful aquatic species. Additionally, avoid disposing of fish entrails in any water sources to prevent contamination.

Using felt wading soles on your boots should be avoided as they can trap debris and organisms that may spread aquatic threats. Instead, opt for rubber soles or other non-absorbent materials. To effectively disinfect your gear, begin by removing all mud, snails, algae, and any other debris from nets, boots, waders, and other equipment. Then, soak and stir all gear and tools in a solution of 10% household bleach or a mixture of 6 oz Sparquat per gallon of water for at least 10 minutes.

If using a household bleach solution, freeze the gear overnight or soak it in a 1:1 solution of Formula 409 antibacterial household cleaner for more than 10 minutes. Alternatively, soak the equipment for over a minute in water that is 120 degrees F or warmer. If Sparquat was used, you can skip this step. Finally, dry the gear in direct sunlight with temperatures of at least 84 degrees F for four hours to ensure that any remaining organisms are eliminated. By following these steps, you can help prevent the spread of aquatic threats and protect the water ecosystems in Rocky Mountain National Park.
