Biology
The Russian River watershed provides food and shelter for many species of invertebrates, reptiles, amphibians, mammals and birds. Wildlife communities in the watershed are an important part of the ecosystem and its health. Read more…
Plant Communities
The upper reaches of the Russian River system originate in the rugged, mountainous terrain of the Inner North Coast Ranges, which include the coastal ranges to the west of Hwy 101 and the Mayacamas Mountains lying to the east. Lying further from the coast and experiencing a rainshadow effect, the ranges to the east are dryer and support large areas of chaparral dominated by Chamise (Adenostemma fasciculatum), Manzanita (Arctostaphylos spp.), and Scrub Oak (Quercus spp.).  Read more….
Russian River Hydrology
The Russian River drains an area of 1,485 square miles that is approximately 100 miles long and from 12 to 32 miles wide. From its source, about 16 miles north of Ukiah, the river flows southward for 90 miles through Redwood, Ukiah, Hopland, and Alexander Valleys, and through the northwestern part of the Santa Rosa Plains. The river then turns abruptly westward at Mirabel Park and flows for 22 miles through a canyon in the mountains before entering the Pacific Ocean at Jenner. Read more…
Geology
The Russian River watershed is predominantly composed of Franciscan formation, which was formed during the Jurassic-Cretaceous age.  Read more…
