Non-point source pollutants of springs throughout the reservation are feral Burros and horses. The Water Resources Program has addressed pollution prevention in several different capacities. Staff from the Department of Natural Resource have flown by helicopter into selected sites which have been heavily impacted by feral animals and are remotely isolated springs.
When feral burros and horses are sited, they are captured using a net gun shot from overhead. Each animal caught is then transported by sling transport below the helicopter to a centralized holding corral. When the roundup of the feral animals is complete they are put up for adoption and removed from the reservation.
In other instances wetland restoration projects of, fencing around the spring site and the placement of wildlife/cattle drinkers outside of the wetland areas has eliminated non-point pollutants and rejuvenated riparian habitat and vegetation associated with the spring wetlands. There are several new additional spring enhancement projects scheduled in 2003.
Sediment control devices (retention dams) have been constructed in selected major watersheds to prohibit and control pollutants from entering spring flows and enhancing water quality standards. The control devices are temporary in nature and are subject to wash out if there are major flood events in the monsoon season. Due to the extreme drought conditions of the region in the past five years, repair and replacement of the control devices have been minimal and water quality is within acceptable standards.
Storm water runoff and drainage from different facilities on the reservation will be surveyed and assessed. Determining the potential contaminants kept, stored and used at each facility and devising best management practices and public education on potential contaminant activities that could enter the community’s ground water aquifer.
The Water Resource Program is also working on acquiring a thorough understanding of all groundwater aquifers throughout the reservation. Using existing well log records of the different aquifers, indicating the depth of the well, depth to water, gallons per minute capabilities and historical water pumping records. Understanding the ground flow of the water can indicate where the water sources may originate and source water protection planning efforts can be initiated to protect the ground water. Another means that may be used to determine the source of ground water would be water chemical analysis of springs and wells within a geographic region.
The various programs of the Hualapai Department of Natural Resources collaborate together under the Performance Partnership Grant to perform a number of activities related to other areas. Water Catchments are built to provide drinking water sources to wildlife and to preserve nearby wetlands and spring sites from grazing and trampling damage.
