Raising Colorado’s Brown Trout – North Delaney Butte Lake
Despite Colorado’s abundant fish populations, most fish cannot successfully reproduce in the wild. And, of those species that are able to reproduce naturally, recruitment (the number of juvenile fish that actually survive to be added to a population) is often too low to support a fishable population. To ensure that there are enough fish to stock every year, CPW sets up spawn-collection sites at lakes and reservoirs across the state.
