 I also ask him what are the main species of fish in the reservoir and just how popular is it? Walleye, rainbow trout. They're all also brown trout in the system, although at a lot lower densities than rainbow trout. Yellow perch, as we mentioned. There's also important prey species for walleye like white suckers. We also have a couple of nuisance species that are in Canyon Ferry. Common carp are kind of everywhere these days. There's plenty of them swimming around.
