General Description

The Isleta reach of the Middle Rio Grande extends from the Isleta Diversion Dam located on the northwest boundary of the Pueblo of Isleta to the San Acacia Diversion Dam near the southern boundary of the Sevilleta National Wildlife Refuge.

The following bullet points highlight the promising features and constraints of the Cochiti reach, which provide opportunities and challenges for projects conducted in this area. This list was developed by the Bosque Hydrology Group.

Promising Features

	Alternating sand bars that can be cleared and leveled for increased flood capacity.
	Islands are forming, suggesting an increase in sediment supply.
	Overbank flooding is occurring in some segments.

	Disassociation of flood plain with river flow.
	Reduction of spring run-off peak river flow.
	Uniform width of channel (~ 200 m) is present.
	Invasion by exotic species: salt cedar and Russian olive.
	Bank stabilization from jetty jacks and exotic species.
	Increased threat of fire due to build up of woody debris and dense riparian vegetation.
	Existence of natural levees.
