Fishing is very good for largemouth bass and panfish. Fish along the tules and around the islands. Use floating or Stillwater sinking lines with streamers and dragonfly nymphs on a twitchy retrieve. Try poppers early and late in the day. This is a small lake that is fun to fish when the bass are on their spawn.
Spring Lake is only a one to one and a half hour drive from the Bay area.
Float tube needed to access good water. Stony Creek Clear, moderate flow, low 40 F's. Fishing is spotty. Best action is with stonefly nymphs fished under an indicator. Try some attractor dries in the afternoon even if the trout are not actively rising.
