The longest tributary of the Sacramento River, it contributes as much as eighty percent of their combined water volume into the Shasta Lake reservoir; the junction of their Shasta Lake arms is 4 miles (6.4 km) northeast of Shasta Dam. The main stem of the Pit River is 207 miles (333 km) long, and some water in the system flows 265 miles (426 km) to the Sacramento River measuring from the Pit River\’s longest source.
The river is a popular destination for fishing, fly fishing, and rafting in its lower reaches, and is used to generate hydroelectricity in the powerhouses below Fall River Mills where the Pit and Fall rivers join, and at Shasta Dam. It is also used extensively for irrigation and conservation purposes.
