l. The South Feather Power Project is a water supply/power project constructed in the late 1950s/early 1960s. The Project is composed of four developments: Sly Creek, Woodleaf, Forbestown and Kelly Ridge, each of which is described below. The Project can store about 172,000 acre-feet (af) of water (gross storage) and has generated an average of about 514.1 gigawatt hours (gWh) of power annually for the past 20 years, since the addition of Sly Creek Powerhouse.
The Sly Creek Development includes:(1)Little Grass Valley Dam--a 210-foot-high, 840-foot-long, rock filled dam on the SFFR with a crest elevation of 5,052 feet (all elevations are in National Geodetic Vertical Datum, or NGVD, unless otherwise specified) and with a 180-foot-long spillway controlled by two 14-feet-high by 40-feet-long steel radial gates that forms a 89,804 acre-foot (af) storage reservoir covering 1,650 acres at a maximum water surface (flood level) elevation of 5,047 feet with the spill gates closed; (2)South Fork Diversion Dam--a 60-foot-high, 167-foot-long, concrete overflow arch dam on the SFFR with a crest elevation of 3,557 to 3,559 feet and with four uncontrolled overflow spillway sections that forms an 87 af diversion impoundment covering about 9 acres at a normal maximum water surface elevation of 3,557 feet; (3)South Fork Diversion Tunnel--a 14,256-foot-long, 11-foot-diameter concrete lined and unlined horseshoe un-pressurized tunnel controlled by two 6-foot-high by 4-foot-long electric hoist slide gates that diverts up to 600 cubic feet per second (cfs) of water from the South Fork Diversion Dam to Sly Creek Reservoir; (4)Slate Creek Diversion Dam--a 62-foot-high, 223.5-foot-long, concrete overflow arch dam on Slate Creek with a crest elevation of 3,552 to 3,554 feet and with three uncontrolled overflow spillway sections that forms a negligible diversion impoundment due to sediment accumulation; (5)Slate Creek Diversion Tunnel--a 13,200-foot-long, 11-foot-diameter, concrete lined and unlined horseshoe un-pressurized tunnel controlled by two 8-foot-high by 6-foot-long manual slide gates that diverts up to a maximum flow capacity of 848 cfs of water (though water rights limit flows to 600 cfs and at times flows are limited to 500 cfs due to high storage volume in the receiving reservoir) from the Slate Creek Diversion Dam to Sly Creek Reservoir; (6)Sly Creek Dam--a 289-foot-high, 1,200-foot-long, zoned earth-filled dam on Lost Creek with a crest elevation of 3,536 feet and with a 649-foot-long spillway controlled by one 16-foot-high by 54-foot-long steel radial gate that forms a 64,338 af storage reservoir covering 619 acres at a maximum water surface (flood level) elevation of 3,531 feet with the spill gates closed; (7)Sly Creek Penstock--a 1,100-foot-long, 90-inch-inside-diameter, steel penstock enclosed in the former outlet tunnel that delivers water to Sly Creek Powerhouse; (8)Sly Creek Powerhouse--a semi-outdoor, reinforced concrete, above ground powerhouse that releases water to Lost Creek Reservoir and that contains one reaction turbine rated at 17,690 horsepower (hp) directly connected to a 13,500-kilovolt-amperes (kVA) generator; (9)Sly Creek Powerhouse Switchyard--a switchyard adjacent to the Sly Creek Powerhouse that contains one 16,000 kVA transformer. Power generated at Sly Creek Powerhouse is delivered from the switchyard to the grid via Pacific Gas and Electric Company's 115 kilovolt (kV) Sly Creek Tap and Woodleaf-Kanaka Junction transmission line; (10)Little Grass Valley Reservoir Recreation Facility--the Little Grass Valley Reservoir Recreation Facility includes Little Beaver, Red Feather, Running Deer, Horse Camp, Wyandotte, Peninsula Tent, Black Rock Tent, Black Rock RV, and Tooms RV campgrounds; Black Rock, Tooms and Maidu Boat Launch areas; Pancake Beach and Blue Water Beach day use areas, Maidu Amphitheater and Little Grass Valley Dam ADA Accessible Fishing trail at Little Grass Valley Reservoir; and (11)Sly Creek Reservoir Recreation Facility--the Sly Creek Recreation Facility includes two campgrounds (Strawberry and Sly Creek), Strawberry Car-Top Boat Launch, Mooreville Boat Ramp and Mooreville Day Use Area on Sly Creek Reservoir. The Sly Creek Development does not include any roads except for the portions of the
