Hunters Hole is located along the Colorado River, in Arizona, approximately three miles north of the U.S. and Mexico Southerly International Boundary. Hunters Hole once consisted of a series of interconnected ponds with adjacent marsh and a few stands of cottonwood-willow. Water levels were maintained by groundwater, irrigation drain flows, and by a connecting channel to the main river channel. Unfortunately, the site has been degraded and most of the habitat lost due to declining water levels, establishment of invasive plant species, and wildfires. Local officials from state, tribal, and Federal agencies have joined together in an effort to restore the area while increasing public safety and border security.
The Yuma Crossing National Heritage Area has secured funding from the Arizona Department of Water Resources to restore 50 acres within the Hunters Hole area and the LCR MSCP has agreed to provide funding for the long-term maintenance. This 50-acre restored area, referred to as a Conservation Area, will contain marsh, riparian, and dry upland habitats. The restoration design is expected to attract native and migratory birds and wildlife species and incorporates restoration needs, international security, cost-sharing, and allows for continued lower Colorado River operations within this reach of the river.
Restoration activities include selective clearing of invasive reeds and saltcedar while leaving existing native trees, installation of infrastructure to allow for managed flooding, and planting with native cottonwood-willow, marsh plants, salt grass, and honey mesquite. A groundwater well and pump were installed to provide a reliable fresh water supply.
Stakeholders in the project include the Bureau of Land Management, U.S. Border Patrol, U.S. Fish and Wildlife Service, U.S. and Mexican Sections of the International and Boundary Water Commissions, Arizona Department of Fish and Game, the City of Yuma, Yuma County Sheriff’s Office, Environmental Defense Fund, National Wildlife Federation, ProNatura Noreste, and private landowners in the Area. Once completed, the native riparian area should provide habitat for mammals and birds, including the endangered southwestern willow flycatcher. This cooperative restoration effort was developed with representatives from Mexico and should complement restoration efforts lead by ProNatura Noreste underway across the river, in Mexico, at Miguel Aleman and serves as a model for other binational restoration efforts.

The Yuma Crossing National Heritage Area, as the lead agency for the Hunters Hole restoration and utilizing funding provided by the Arizona Water Protection Fund, cleared, leveled, and installed irrigation infrastructure in the fall of 2011. Riparian planting was completed in the spring of 2012. Routine maintenance activities consist of invasive plant species control, road maintenance, and irrigation scheduling. The LCR MSCP will maintain ownership of the property and manage the property for LCR MSCP covered species throughout the life of the program. Automation of the irrigation system is being implemented to reduce on-site labor and lower the annual operating cost of the project.
