The Isleta Reach is a 48-mile reach of the Rio Grande from the southern boundary of the Pueblo of Isleta to the San Acacia Diversion Dam. Agriculture is the primary land use surrounding the Isleta Reach.

The largest communities are the Village of Los Lunas and the City of Belen. The Rio Grande in the Isleta Reach is susceptible to low flows and intermittent drying from irrigation water withdrawals especially in times of severe drought and declining water supply. The National Audubon Society will work with its partners to lease and deliver water to key wetland areas in the Isleta Reach that lack adequate water supply to support riparian, wetland and environmental function and benefits.

Water deliveries are targeting times of drought and associated river drying. These deliveries will sustain wildlife habitat for imperiled species including southwestern willow fly catcher and Rio Grande Silvery Minnow, as well as a myriad of bird species that rely on a vibrant Rio Grande.
