The South Fork Trinity River is one of the largest undammed river systems in California. The river and its tributaries support important populations of threatened and endangered salmon and steelhead and old-growth forest dependent wildlife species. The river and tributaries also offer outstanding outdoor recreation opportunities.
The federal coho recovery plan identifies Olsen Creek as a high priority restoration target. This Hayfork Creek tributary may also provide important thermal refugia for coho and other anadromous fish.
