Colorado lakes and reservoirs hold a varied mix of fish, with trout prominent, kokanee salmon in some large mountain reservoirs, walleye in many large reservoirs, and lake trout in some mountain lakes. The species mix varies by water, so a statewide list cannot confirm what lives in a particular lake. Use Colorado Parks and Wildlife’s (CPW) lake-level information and check that water’s current regulations before fishing.
Common fish groups in Colorado lakes and reservoirs
These are representative examples, not a checklist for every lake. CPW describes fishing opportunities for more than 35 species across Colorado’s waters, but that statewide figure is not a count of species found specifically in lakes. The state has more than 1,300 lakes and reservoirs, and their fish populations differ.

Trout
Trout are a major part of lake fishing in Colorado. CPW says most state lakes and reservoirs are managed as put-and-take fisheries because natural reproduction or juvenile recruitment often does not sustain a fishable population. That does not mean every lake is stocked on the same schedule, or that all trout in lakes are stocked. CPW’s stocking information focuses on recently stocked catchable trout, approximately 10 inches long.
Kokanee salmon
Kokanee are landlocked Pacific sockeye salmon associated with large, fluctuating mountain reservoirs. CPW says they are restocked in 26 Colorado lakes and reservoirs. In fall, kokanee swim upstream to spawn and die afterward; spawning and any related giveaway timing can vary from year to year.

Walleye
CPW says walleye have been introduced into most large warm- and cool-water reservoirs since 1949. This is a broad association, not confirmation that walleye are present in every large reservoir.
Lake trout
Lake trout occur in mountain lakes and are usually found in deeper water. CPW notes that anglers may find better opportunities in shallower areas during fall and spring, as well as during ice fishing.
How to find the fish in a particular lake
For a specific water, combine CPW’s lake-level information with survey and stocking details. Each resource answers a different question, and none should be treated as a complete, up-to-date inventory on its own.

- Fishing Atlas: Search fishing opportunities by species, interest, or proximity. The atlas includes details such as accessible fishing access, stocked waters, boat ramps, and special fishing regulations.
- Fishery survey summaries: Review population trends and management information where a summary is available. Coverage and survey dates vary. CPW says high-priority waters may be surveyed annually, while some smaller, remote, or lightly used waters may be surveyed every five to ten years.
- Fish stocking report: Check recent catchable trout stockings. The report is updated every Friday during fishing season, but its report date may not be the exact date fish were stocked. It is not a complete fish inventory.
- Current fishing regulations: Check the rules for the specific water, including any special regulations, before you go.
What to compare when choosing between lakes
If you are deciding where to fish, compare the target species and type of fishery rather than relying on a general state list. Look at whether the fish are stocked or naturally sustaining, how recent and extensive the latest survey is, what access or boat-ramp options are available, and whether special rules apply. A lake with no recent survey summary is not necessarily fishless; it may simply be surveyed less often.
