# Reservoir Bench > Western US reservoir levels tracked daily from official Bureau of Reclamation and California DWR gauges. Reservoir Bench publishes daily surface elevation, storage, and percent-full for nine major Western US reservoirs — Lake Mead, Lake Powell, Lake Mohave, Lake Havasu, Flaming Gorge, Blue Mesa, Navajo, Shasta, and Oroville — from the Bureau of Reclamation RISE API and California DWR CDEC. Every page carries an as-of date; every series is downloadable as CSV. Colorado River shortage-tier thresholds and the post-2026 guidelines process are documented with citations to USBR source documents. ## Pages - https://reservoirbench.com/ - https://reservoirbench.com/lake-mead/ - https://reservoirbench.com/lake-powell/ - https://reservoirbench.com/lake-mohave/ - https://reservoirbench.com/lake-havasu/ - https://reservoirbench.com/flaming-gorge/ - https://reservoirbench.com/blue-mesa/ - https://reservoirbench.com/navajo/ - https://reservoirbench.com/shasta/ - https://reservoirbench.com/oroville/ - https://reservoirbench.com/shortage-tiers/ - https://reservoirbench.com/post-2026-guidelines/ - https://reservoirbench.com/about/ - https://reservoirbench.com/data/ ## Data downloads (stable URLs, updated on the site's cadence) - https://reservoirbench.com/data/lake-mead.csv — Lake Mead daily elevation (ft) and storage (AF), Hoover Dam - https://reservoirbench.com/data/lake-powell.csv — Lake Powell daily elevation (ft) and storage (AF), Glen Canyon Dam - https://reservoirbench.com/data/lake-mohave.csv — Lake Mohave daily elevation (ft) and storage (AF), Davis Dam - https://reservoirbench.com/data/lake-havasu.csv — Lake Havasu daily elevation (ft) and storage (AF), Parker Dam - https://reservoirbench.com/data/flaming-gorge.csv — Flaming Gorge Reservoir daily elevation (ft) and storage (AF), Flaming Gorge Dam - https://reservoirbench.com/data/blue-mesa.csv — Blue Mesa Reservoir daily elevation (ft) and storage (AF), Blue Mesa Dam - https://reservoirbench.com/data/navajo.csv — Navajo Reservoir daily elevation (ft) and storage (AF), Navajo Dam - https://reservoirbench.com/data/shasta.csv — Shasta Lake daily elevation (ft) and storage (AF), Shasta Dam - https://reservoirbench.com/data/oroville.csv — Lake Oroville daily elevation (ft) and storage (AF), Oroville Dam All data is sourced from U.S. government public-domain datasets; sources and update cadence are described at https://reservoirbench.com/about/
