Lassen Lodge Hydroelectric Project, FERC P-12496
This proposed Hydro project on the upper reaches of the South Fork of Battle Creek will have a 6' high by 94' wide diversion dam at elevation 4,304 feet. A 10' x 20' intake structure will be to the side of the dam. A 4' diameter pipe will extend downstream. Then a 3' high pressure line will drop another 1.4 miles to a powerhouse at elevation 3,350 feet. The powerhouse will have a maximum flow of 105 cfs, but optimal flow will be 95 cfs
