No published figure covers depth, so learn it as you fish. Weed, then depth: that is the order to fish a water of this kind. Still water like this holds fish on the edges rather than out in the open. Species logged across Mariposa County include rainbow trout, brook trout, brown trout, Sacramento sucker and black crappie. The county figures include rivers and lakes alike. On Upper Merced Pass Lake the obvious spot is not always the productive one.
Long-run averages give August about 56°F and February about 26°F. The season stretches long at both ends here. Some winters give nothing at all, so plan for open water. The cooler months are the comfortable ones to fish here. Plan around that when you fish Upper Merced Pass Lake.

Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Bank access can be seasonal on ground like this. Close seasons apply to some species and not others.
