- Pit River
The Pit River or Pitt River is a major river watershed draining Northeastern California into the State's Central Valley. The Pit, the Klamath and the Columbia are the only three rivers in the U.S. that cross the Cascade Range.
The longest tributary of the
Sacramento River, it contributes as much as eighty percent of their combined water volume into Lake Shasta; the junction of their Lake Shasta arms is four miles northeast of Shasta Dam. The Pit River is approximately 315 miles long (measuring from its longest source as is standard USGS practice.) This 58 mile South Fork Pit River - West Valley Creek - Cedar Creek source originates just southeast of Buck Mountain in the Warner Mountainsin the extreme southeastern corner of the Modoc National Forestnine miles west of the Nevadaborder. The Pit River drains a sparsely-populated volcanic highlands area, passing through the south end of the Cascade Rangein a spectacular canyon northeast of Redding. The river is so named because of the pits the Achumawi dug to trap game that came to water at the river.
The Pit River rises in several forks in Modoc and Lassen Counties in the northeastern corner of California in the
Warner Mountains. The South Fork is formed from the confluence of several creeks in Jess Valley13 mi (21 km) northeast of Madeline and flows west through a narrow canyon, past Likely, then generally through a broad ranching valley where its waters are diverted for irrigation and waterfowl conservation in an extensive system of canals. The 30 mile long North Fork - Linnville Creek tributary begins 5 miles southeast of the town of Davis Creek. It flows generally SSW, joining the South Fork from the north near Alturas.
The combined river flows WSW in a winding course across Modoc County, past Canby and through the
Modoc National Forestin a narrow gorge called Stonecoal Valley. It turns south to flow past Lookout and into northern Lassen County, past Bieber to emerge into the ranching region of Big Valley. North of Little Valley it runs east into northeastern Shasta County, passing through the Cascades in a serpentine canyon in the Shasta National Forest. It flows past Pittville, McArthur, and Fall River Mills to join the Sacramento Riveras the eastern arm of Shasta Lakereservoir, approximately 15 mi (24 km) north of Redding. The lower 30 mi (50 km) of the river now forms the longest "arm" of the five of Lake Shasta, which is formed by Shasta Damon the Sacramento downstream from the original confluence.
Goose Lake was once the source of the North Fork Pit River, but it now usually an enclosed basin. During rare high water levels, the lake still spills out into the Pit River system. [ [http://www.pitriveralliance.net/ Welcome to the Pit River Watershed Alliance ] ]
The river is a popular destination for
fly fishing, rafting in its lower reaches, and is used for hydroelectric energy both in the powerhouses below Fall River Mills and at Shasta Dam. It is also used extensively for irrigationand conservation purposes.
The Pit River was the site of several military expeditions against local Indian Tribes during the 1850's, each known as the
Pitt River Expedition.
