The following on behalf of the Office of the State Engineer and Interstate Stream Commission:
The NM Interstate Stream Commission (ISC) will be conducting the Animas and San Juan River Basin Crop Survey from Wednesday to Friday, August 5-7, 2026. The annual crop survey is conducted to document New Mexico’s use of Colorado River Basin water in compliance with the 1948 Upper Colorado River Basin Compact. The Animas basin, from the state line to the confluence, and the San Juan River basin, from Navajo Reservoir to the Hogback, are the focus of the August Crop Survey. Staff will be driving slowly, documenting crop types and irrigation methods for irrigated agriculture in three state vehicles with G-plate license plates. The vehicles may be seen stopped on the shoulder of the road while ISC staff identify irrigated tracts of land.
The ISC is a sister agency to the New Mexico Office of the State Engineer (OSE). Please note that the annual ISC Crop Survey is not conducted for the purpose of OSE water rights compliance; it is done to support interstate compact compliance within the Colorado River Basin.
