Diamond Lake, near Diamond Lake, Oregon, within the Umpqua National Forest, is famously known as "Oregon's Gem of the Cascades." This picturesque lake is a premier recreational fishery, celebrated for its exceptional rainbow trout, which grow robust on the lake's abundant insect hatches. The Oregon Department of Fish & Wildlife (ODFW) extensively stocks these trout, ensuring consistent angling opportunities. Additionally, tiger and brown trout are stocked as a conservation measure against invasive species, requiring strict catch-and-release.
Optimal fishing conditions for trout prevail in the lake's clear, cool waters, with current early summer temperatures ideal for cold-water species. Anglers are reporting good success, with many achieving their limits. Trolling with various lures from a boat is highly productive for covering water and locating active trout. Bank fishing with bait or casting lures from accessible points, including the South end and main boat ramps, also yields excellent results.
Access to Diamond Lake is well-developed, featuring resorts, multiple campgrounds, and open boat ramps. Conservation is paramount; anglers must strictly adhere to all ODFW regulations, including specific bag limits for rainbow trout and mandatory catch-and-release for tiger and brown trout. Diamond Lake offers a vibrant and deeply rewarding angling experience, combining consistent trout catches with the breathtaking natural beauty of the Cascades.
