Common questions

How full is Lost River Reservoir?

Reclamation publishes the water surface elevation for this gauge but not a percent-full figure, so we don't show one rather than estimate it.

How often is this page updated?

The page is rebuilt automatically every day from Reclamation's published data. Values can be revised later by the source agency.

Where does the data come from?

The U.S. Bureau of Reclamation's RISE data portal (data.usbr.gov). Forecasts come from the National Weather Service.
