Equus Beds Surface-Water Quantity

  • The source water for the Equus beds artificial recharge project is the Little Arkansas River. During the demonstration phase of the project through 2002, according to permit conditions set by the Kansas Department of Agriculture, Division of Water Resources, water could be diverted from the river for recharge under the following conditions:
    • At the Halstead Recharge site, from April 1 through September 30, when streamflow at the USGS stream gage Little Arkansas River at Highway 50 near Halstead (07143672) exceeded 42 ft3/s .
    • At the Halstead Recharge site, from October 1 through March 31, when streamflow at the USGS stream gage Little Arkansas River at Highway 50 near Halstead (07143672) exceeded 20 ft3/s.
    • At the Sedgwick Recharge site, throughout the entire year, when streamflow at the USGS stream gage Little Arkansas River near Sedgwick, KS (07144100) exceeded 40 ft3/s.
  • Permit guidelines for Phase I full scale recharge operations established by the Kansas Department of Agriculture, Division of Water Resources, in August 2005, require the following conditions for water to be diverted from the river for recharge:
    • At the Halstead Recharge site, from April 1 through September 30, when streamflow at the USGS stream gage Little Arkansas River at Highway 50 near Halstead (07143672) exceeds 57 ft3/s.
    • At the Halstead Recharge site, from October 1 through March 31, when streamflow at the USGS stream gage Little Arkansas River at Highway 50 near Halstead (07143672) exceeds 20 ft3/s.
    • At the Sedgwick Recharge site there are currently no permit regulations established for full scale recharge operations based on streamflow at the USGS stream gage Little Arkansas River near Sedgwick, KS (07144100).
