Conditions

Water clarity is slightly off from wind chop, but fish are still feeding well. Flow is running at 4,010 cfs as of August 26, with the reservoir at 75% full. Walk-and-wade access is confined to the banks at current levels, though rocks near the dam hold plenty of trout. Focus on balanced leeches, minnow patterns, larger caddis, and streamer patterns to work the edges.

Techniques

  • Streamer fishing bass is slowly picking up and low and slow is still the name of the game.
  • Working the rocks close to the dam can be very productive. Bobber setups with balanced leeches, minnow patterns, and larger caddis are finding a mix of trout and bass.
