Millsite State Park

Millsite is an open reservoir shared with motorboats and waterskiers; the official park page does not describe a roped-off swim beach, lifeguard service, or graduated shallow entry. Families should supervise closely and stay clear of the boat ramp/launch lane. Reservoir was reported at 31% capacity at time of research, which can mean uneven, rocky, or muddy shoreline entry rather than a groomed beach.

No significant hike is required. The swimming area is close to parking and access.

Day-use/park entry fee is collected via self-service fee envelope at the entrance station or online through Utah State Parks' Park Pass system; the exact dollar amount was not published on the pages reviewed. Parking is at the developed day-use area near the campground and boat ramp, not roadside.

Official sources (Utah State Parks, Wikipedia) confirm the reservoir supports boating, waterskiing, and fishing generally. Non-motorized craft such as kayak, canoe, or paddleboard are not explicitly named in any source found, and no restriction against them was found either - their permissibility is likely but unconfirmed, so they are intentionally left out of the allowed list per the no-guessing rule.

As of the most recent park update, Stage 2 fire restrictions were in effect (no open fires of any kind; only approved portable camp stoves permitted), and the boat ramp was posted 'Launch At Your Own Risk' due to low reservoir water levels.
