Smith River

About

Smith River, California — 1982 Wild and Scenic, 6th Generation Working River. Flow is the first thing a boater checks, and on the Smith the record runs deep. Continuous streamflow measurements began in 1932 at gage 11532500 near Crescent City, which remains the watershed's principal discharge station. The long-term average sits near 3,748 cubic feet per second, and paddlers find the river most cooperative between 1,000 and 5,000 CFS across its Class II–III water. Because the Smith is undammed, that gauge record offers an unusually clean baseline of natural runoff, one hydrologists still lean on across California's North Coast.

The river system is really three runs braided into one drainage. The South Fork carries Class II–III water through a redwood canyon and is the most popular of the forks. The Middle Fork tightens into a Class III–IV wilderness gorge. Below the confluence, the main stem eases to Class I–II as it slides toward the Pacific, prime steelhead water for anglers working the lower river. The whole drainage covers roughly 750 square miles, and more than 300 miles of it carry Wild and Scenic designation.

People have relied on these runs far longer than any survey. The watershed was the homeland of the Tolowa Dee-ni', who built a salmon-based culture along the river across thousands of years, drawing on returns that ranked among the most productive on the Pacific Coast. Commercial logging arrived with the gold rush: Del Norte County's first lumber mill was established at Crescent City in 1853, as settlers turned to the coast's stands of coast redwood, Douglas fir, and cedar. In 1870, a joint-stock company organized a sawmill near Lake Earl that grew into the Crescent City Mill & Transportation Company.

Timber crews pushed steadily deeper into the redwood country. In the 1920s, Hobbs, Wall & Company built a mill in the upper Mill Creek watershed and laid the Del Norte and Southern Railroad to haul logs down to the Crescent City mills. By the 1930s much of the accessible old-growth had already fallen, and the boom finally broke in 1939, when the county's largest mill shut down. Through all of it the Smith itself was never dammed or diverted, though decades of heavy cutting left a lasting mark on the forests draining into it. Systematic science followed the saws: the U.S. Geological Survey published Water-Supply Paper 1254, "Geology and Ground-Water Features of the Smith River Plain, Del Norte County, California," in 1957, prepared in cooperation with the California Department of Public Works' Division of Water Resources — the first comprehensive assessment of the lower river's aquifers, soils, and flow. Under the federal Clean Water Act of 1972 and the North Coast Regional Water Quality Control Board, the basin has since been monitored for the sediment and temperature effects of a century of logging.

Permanent protection came in two steps. The 1981 Wild and Scenic designation was the principal conservation victory, and in 1990 Congress established the Smith River National Recreation Area within the Six Rivers National Forest, extending protection across the largest undammed river system in California. Today the Smith works as both a living fishery and a rare benchmark — a free-flowing Western river measured, logged over, and ultimately left intact.
