• Where to Fish on Blue Diamond Lake

  Depth is not on record here, which means reading the ground instead. On a natural lake the weed line and the shelf beyond it do the work. Read the surface for the wind lane, then fish the edge of it. Records held for Okanogan County cover rainbow trout, largemouth bass, sockeye salmon and yellow perch. Protected fish appear in the records for this area, so treat the list as information, not an invitation. Take Blue Diamond Lake a stretch at a time.

• Tackle & Baits

  The access position is unclear from public sources. Mapping is blank for access, so scout the approach before committing the car. A small crankbait along the drop and a worm in the thick stuff cover the bass. A phone call first saves an afternoon. Where the way in crosses private ground, ask first. Fertilizer Lake, 1.1 miles away, makes the obvious fallback. Treat access at Blue Diamond Lake as something to verify.
