What is the current water level of Costilla Reservoir?

This lake reports storage (758 acre-ft as of Jul 14, 2026, 11:30 AM (UTC-06:00)) but no elevation gauge — its managing agency does not publish a pool-elevation reading here.

Is Costilla Reservoir full right now?

Its managing agency does not publish a %-of-conservation-pool-full figure for this lake, so we show the bare level rather than estimate one.

Where does this data come from?

From USGS site 08253900, retrieved Jul 14, 2026, 10:55 PM (UTC+00:00). See the official link and the methodology page for the full source and update cadence.
