The Imperial Irrigation District is preparing a water apportionment plan for Imperial Valley growers to rein in a projected water overrun after the federal government declared a water shortage, reducing the amount of water that Arizona, Nevada and Mexico can claim from the Colorado River.

The IID holds the largest and most secure federal entitlement on the Colorado River, but current Bureau of Reclamation projections show the district exceeding its allocation by more than 92,000 acre-feet of water this year as grain prices reach record highs following Russia’s invasion of Ukraine.
