No, just the Stanislaus River.
However there are several nice lakes in the area. White Pine lake down near Arnold, and Alpine lake about 30 minutes further up the highway just passed Bear Valley.
There is a natural water slide in the park if you can find it. You submerge your self in these smooth indents in one of the shallowest parts of the river and it sends you down to this almost still area where you get out and walk back up for another trip down. I've seen it get fairly populated
Yes nearby but not in park.
Also Spicer Reservoir, between Arnold and Bear Valley.
There are beautiful trails for hiking and plenty of campsites, but no...not a lake in the park. There is a river close by that we also went to, for fishing, but not sure if boating is allowed.
No lake just a river
