Big Wood Ground Water Management Area Advisory Committee

  1. Meeting Materials
  2. Management Actions Annual Reports


In 1991, IDWR designated a GWMA for the Big Wood River Basin after ground water monitoring wells showed that ground water levels were declining in the basin. In recent years, landowners with senior surface water rights in the Big Wood River and Little Wood River have alleged that ground water pumping in the upper Wood River and Silver Creek drainages was depleting flows in the rivers and reducing river flows diverted for irrigation. This dispute resulted in attempted litigation and the submittal of several draft plans to IDWR to address the controversy. In response, IDWR the advisory committee to find a solution to the controversy.
