1 min read


DENVER (KDVR) — Colorado Parks and Wildlife recently discovered an invasive species in Lake Granby.

According to CPW, multiple crayfish were found at the lake during a routine Aquatic Nuisance Species sampling on Aug. 17. On Aug. 31, the samples were confirmed to be rusty crayfish.

After discovering the existence of the invasive species, CPW rangers and area aquatic biologists set traps around Lake Granby, below the dam on the Colorado River and around other lakes that are in close proximity to determine if the species was present in other waters.

CPW said the traps in the surrounding lakes did not contain crayfish, and the trap below the Colorado River dam was empty as well.
