The Upper Snake-Rock (USR) watershed is one of eight special emphasis
watersheds in the NRCS Conservation Effects Assessment Project (CEAP). Land
use in the USR is 37% irrigated agriculture, <1% dryland agriculture,
and 60% range and forest with a history of various conservation practices
and long-term water quality data. Our CEAP research efforts in the USR are
targeted toward the Twin Falls Irrigation Tract, an 82,000 ha irrigation
district with approximately 30% sprinkler irrigation and 70% furrow irrigation. |
