San Joaquin Millerton Lake State Recreation Area has over 40 miles of shore land for water sports.
Recreation includes swimming, fishing, and boating.
The lake was created by construction of the Friant Dam across the San Joaquin River in 1944. The hills surrounding the lake provide good hiking opportunities. Wildlife in the park includes ground squirrels, cottontails, mule deer, badgers, and bald and golden eagles. During winter, the park has special boa tours that view the bald eagles. The park contains the original Millerton County Courthouse, built in 1867.
