Student Project: Interstate Water Compacts: California

This research guide explores Interstate Water Compacts in the United States at both the federal and state levels. Specifically, it will explore the law of California, Arizona and Colorado.

Background on Interstate Water Compacts in California

California is a party to four interstate water compacts: The Colorado River Compact of 1922, the first interstate water compact agreement it entered. (The Boulder Canyon Project further clarified California’s apportionment of the water in the Colorado River from the Colorado River Compact); the California Nevada Compact; the Klamath River Compact; and the Goose Lake Interstate Water Compact with Oregon. These interstate water compacts are a vital part of California’s water resources, as water can be scarce in California due to drought and climate change. California codified most of its interstate water compacts in the California Water Code. The interstate compacts are governed by both state and federal Law.
