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.
Madden Creek is one of the few lower South Fork tributaries with good water quality due to its relatively undisturbed watershed. Cold water from Madden Creek creates a critical thermal refuge for coho salmon migrating up the South Fork and the lower segment of the creek offers suitable habitat for coho, Chinook, and steelhead.
