Big Wood Ground Water Management Area Advisory Committee

BWGWMA Advisory Committee Overview

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.

  • Corey Allen, Sun Valley Company
  • Cooper Brossy, Big & Little Wood Water Users Association
  • Rod Hubsmith, American Falls Reservoir District 2
  • Sharon Lee, Individual
  • Pat McMahon, Chair, Galena Ground Water District
  • Justin Stevenson, Chair, South Valley Ground Water District
  • Carl Pendleton, Board Chair, Big Wood Canal Company
  • Pat Purdy, Owner, Picabo Livestock Company, Inc.
  • William Simon, Camas Prairie Water Users
  • Nick Westendorf, Big & Little Wood Water Users Association
  • Brian Yeager, Public Works Director, City of Hailey
  • Ron Taylor (Ex-officio Member), Idaho State Senate
  • Jack Nelsen (Ex-officio Member), Idaho House of Representatives
