Abstract: A water balance for the Carson Division of the Newlands Project in Northwest Nevada was created to identify the potential recovery of irrigation drainage effluent from the shallow aquifer for crop irrigation. Results from a pilot study have demonstrated that drainage effluent from the shallow aquifer can be utilized for crop irrigation. Reduced headgate deliveries in exchange for recovered drainage water would free approximately 55,000 ac.ft. of high quality water (0.32 dS/m-0.60 dS/m) in Lahontan Reservoir for the wetlands located down gradient from the irrigated lands. Exchanging current drainage inflow with uncontaminated reservoir water, would benefit the wetlands.
