The Bureau of Reclamation has authority for river channel maintenance on the Rio Grande between Velarde, New Mexico, and the headwaters of Caballo Reservoir. As a result, Reclamation monitors changes in the river channel in order to identify sites that require maintenance. Monitoring includes channel and levee capacity evaluations in an effort to keep track of river maintenance priority sites that may provide damage to riverside facilities.

There are two priority sites on the Pueblo of Cochiti that require extensive maintenance: River Mile 231.3 about one mile down stream of the Cochiti Dam and River Mile 231.3 about three miles downstream of the Cochiti Dam and River Mile 231.3 about three miles downstream of the dam. The maintenance activities of these priority sites have been analyzed in the environmental assessment subsequent to this Finding of No Significant Impact.
