About seven miles southwest of Newport, adjacent to Highway US-2. Open fishing season is the 4th Saturday in April through October 31. Largemouth bass, yellow perch, bullheads, rainbow and brown trout are available. In an effort to improve the fishery, Diamond has a cooperative net pen project that releases 12,500 rainbow trout in addition to the stocked catchable-size rainbows and browns. This year, around 700 larger triploid and a few broodstock rainbows will be added to improve the fishery.
Diamond Lake has public access and resorts.
