the most part, the surface and groundwater resources of the Valley are
interconnected -- called conjunctive use. Groundwater quantity and
quality depend upon aquifer recharge from the water diverted out of the
North Platte River system. This surface flow supplies 24 irrigation
districts and canal companies with irrigation water.
benefits are derived from water flowing through hundreds of miles of
canals and laterals throughout the Valley; extending from the Wyoming-
Nebraska state line running 120 miles east to Lake McConaughy.
Surface water supplies accumulate each
winter as snowpack in Wyoming's mountains and basins. The melting snow
is "banked" in North Platte River system
reservoirs in Wyoming until needed by the irrigation districts and
companies supplying the North Platte Valley.
In addition to
irrigation, the surface diversions also supply municipal and industrial
uses, stock and domestic wells, habitat for fish and wildlife,
additional groundwater irrigation and a variety of recreational
purposes. Other benefits from river diversions are groundwater
sustainability, as well as improved groundwater quality.
