The legislation would create a new program under the Department of Interior to use satellite imagery to estimate how much water is lost to evapotranspiration from crops, which makes up one of the largest chunks of water consumption in arid environments like the American West. Evapotranspiration is the water from the ground and surfaces of plants that is lost to the atmosphere.
Sen. Catherine Cortez Masto, D-Nev., and Rep. Susie Lee, D-Nev., reintroduced the Open Access Evapotranspiration Data Act on their respective congressional floors Thursday alongside Sen. John Hickenlooper, D-Colo., and Reps. Chris Stewart, R-Utah, Jared Huffman, D-Calif., and Burgess Owens, R-Utah.

Lee said that concept would expand on the OpenET program — a public-private partnership supported by NASA, the Desert Research Institute and the Environmental Defense Fund — nationwide in order to provide water managers and farmers with […]
