The Mokelumne River Day Use Area is a popular access point to the Mokelumne River and for visitors to the Mokelumne River Fish Hatchery. Located 15 miles east of Lodi off Highway 12 and at the base of Camanche Dam, nearly a mile long stretch of the river awaits visitors in a natural setting. Popular activities include picnicking, strolling along trails, fishing for steelhead and salmon, and wading and swimming. This park also affords rafting access to a beautiful stretch of river downstream.
There are several picnic sites also available. The day use area is open from sunrise to sunset, 365 days a year. There are 14 picnic sites with tables and barbecues, plus undeveloped riverside access. Special consideration has been given to visitors with disabilities by providing an ADA accessible vaulted restroom, trail, picnic site and fishing pier.
Fishing season from the day use area runs from January 1 to March 31 and from the 4th Saturday in May to October 15. The closed periods help boost the steelhead and salmon fishery. Of special interest is the salmon spawning season, which is October through December. During this time many large adult salmon can be seen returning from the ocean. In November, at the peak of spawning season, hatchery visitors have the opportunity to watch hatchery staff collect eggs. The Mokelumne River Fish Hatchery is open seven days a week, from 7:00 a.m. to 3:00 p.m.
