Putah Creek flows from the coastal mountains of Lake and Napa counties eastward to the Yolo Bypass where it connects to the Sacramento-San Joaquin River Delta. Native rainbow trout still swim in the upper mountain reaches, and historically, salmon and steelhead spawned in the lower and middle portions of the creek. Completed by the US Bureau of Reclamation in 1957, Monticello Dam transformed Putah Creek from a stream with seasonal flows to one with constant cold water exiting from the depths of Lake Berryessa. Much of Putah Creek’s water is diverterted six miles below at the diversion dam where it is sent to farms and cities in Solano County.
In the early 1970’s the interdam stretch was stocked with brown and rainbow trout by the California Department of Fish and Game. Some of these fish began reproducing naturally creating a highly productive wild trout fishery that continues to thrive today. Putah Creek has seen a tremendous increase in use with the growth of recreational fishing over the last two decades and the large increases in population of Northern California. Because of its close proximity to San Francisco, Sacramento and the Napa Valley, Putah continues to see increasing use, and fisherman from all over of the US and world have fished the creek. Putah Creek Trout is a 501-c-3 nonprofit* organization committed to the protection and improvement of the wild trout fishery in Putah Creek.
