Great outing! Pinecrest is a gem, my favorite in the Calaveras pass. Just north in the El Dorado pass, is Loon Lake and the entry point to the Rubicon Trail, which starts at the northern lake campground. Beautiful clear lake with larger trout on average, and you can spot the schools from the higher rocks, where they're eager to chase Kastmasters and Roostertails..
The quality would be better, and the South Fork Stanislaus River is open last Saturday in April through November 15th with barbless hooks and artificial lures only.
