Hydrology in the Yuba River Watershed

New Bullards Bar Reservoir2

Middle Fork Yuba River Originating in a bowl-shaped valley in Moscove Meadow, the Middle Fork flows north into Jackson Meadows Reservoir, then turns west, descending steeply into a gorge, defining over almost its entire length the boundary of Nevada County in the north and Yuba County in the south. The river bends to the southwest, then west again, receiving Kanaka Creek from the right and Grizzly Creek from the left. It intersects California State Route 49 about 2 miles (3.2 km) northwest of North San Juan, then a few miles after joins with the North Fork Yuba River.

Gathering numerous snowfed tributaries, from the right near the town of Washington. The it runs west through a marshy, lake-filled valley, river continues west into the foothills, crossing shadowed by Interstate 80. The river then flows under State Route 49. Its mouth is on the east shore into Lake Spaulding, which is formed by Spaulding of , formed by a dam across the Dam. After escaping from the dam the river plunges Yuba River. Jackson Meadows Reservoir3

Flows in the watershed are typical of tributaries with headwaters in the Sierra Nevada. Flows are highest in winter and spring, decreasing quickly in late spring. In 2008, the SWRCB approved the Lower Yuba River Accord Agreement, which is now fully operational. The agreement combines increased instream fisheries flows for wild, native salmon and steelhead, with increased supplemental water supplies for cities and farms.

From the joining of the North and Middle Forks, the Temperature is also a significant water quality Yuba flows southward, then southwest, through the concern in the Yuba River Watershed. Warming Sierra Nevada foothills, forming the Yuba-Nevada water temperatures can be attributed to dams, County border. The river widens into the main arm water diversions, inadequate shading by limited of Englebright Lake near French Bar, and is joined by South Yuba3 riparian canopy, and low instream flows.

Low flows and high temperatures on the South and Middle Yuba Rivers, along with the legacy of sediment from hydraulic mining, continue to contribute to problems for cold-water aquatic communities.

The Yuba River Watershed is also home to a large number of bird species and a stopover point for migrating birds. Commonly seen mammals include mule deer, raccoons, skunks, opossum, and coyote. More elusive are the gray fox, bobcat, ringtail, mountain lion, and black bear.

There are more than 100 jurisdictional dams or diversions in the Yuba River Watershed. The diversions convey water to local users and to users in the Bear and North Fork American River Watersheds. A large amount of water is diverted from the watershed at Lake Spaulding on the South Fork for irrigation and power generation. The Watershed alone supports 20 reservoirs and 20 hydroelectric dams. Englebright Dam marks the division between the Upper and Lower Yuba River. The dam was completed in 1941 to capture gold-rush era hydraulic mining debris that threatened downstream areas with floods. Englebright Reservoir has a storage capacity of 45,000 acre-feet and provides electricity and recreational opportunities. Spawning Chinook salmon
