DeWeese Reservoir, a short drive from Westcliffe, is a much-loved place to fish in the Wet Mountain Valley. It is an easy-to-reach spot with quiet water, good wildlife viewing, and big valley views, and it is managed as a State Wildlife Area, which works a little differently from a state park.
The main thing to grab before you go is a pass. State Wildlife Areas are managed by Colorado Parks and Wildlife mainly for hunting, fishing, and habitat, and they are paid for largely by license dollars. So everyone 16 or older needs a valid hunting or fishing license, or a State Wildlife Area pass, just to be on the property, not only to fish. Children under 16 do not need one. It is a simple thing to pick up ahead of time, and then you are set.
Good to know on boats: vessel use here is allowed only while fishing, so plan to leave the paddling craft or personal watercraft at home and bring your fishing gear instead. Other quiet activities like picnicking, hiking, and wildlife viewing are welcome too.
Rules at State Wildlife Areas, including pass requirements and any seasonal or health-related closures, can change. Before you go, check the current rules and conditions for DeWeese Reservoir State Wildlife Area with Colorado Parks and Wildlife.
