Williams Creek Reservoir is a wildlife area, not a state park
Williams Creek Reservoir, reached up the Piedra Road country north of Pagosa Springs, sits just across the line in Hinsdale County and is a State Wildlife Area, so access follows hunting and fishing rules rather than state park rules.

North of Pagosa Springs, the drive up the Piedra Road country begins in Archuleta County and climbs into the high San Juans. Near the end of that road sits Williams Creek Reservoir, a lake ringed mostly by national forest. One map detail is worth knowing first: although Pagosa Springs is its gateway town, the reservoir itself lies just across the county line, in neighboring Hinsdale County.
The label that matters most for visitors, though, is not the county — it is the legal one. Williams Creek Reservoir is a State Wildlife Area, not a state park, and that difference changes the entry rules. State Wildlife Areas are bought and managed mainly for wildlife and for the people who hunt and fish. So instead of a parks pass, access for anyone 16 and older generally calls for a valid hunting or fishing license or a State Wildlife Area pass. Rules for young people differ by age, and the specifics are set by Colorado Parks and Wildlife.
There are also use limits on the water. Boating is allowed at Williams Creek, but operating a vessel in a way that throws a fast, whitewater wake is not. Quiet, low-speed boating fits the place; a ski-boat does not.
Because regulations, pass requirements, and seasonal access can change, this note points you to the source rather than quoting current rules. Confirm what you need before you go, so you arrive with the right pass or license in hand.
