Available Groundwater Determination
Technical Memorandum

Wind/Bighorn River Basin Water Plan II
Groundwater Study Level I

The present Available Groundwater Determination Technical Memorandum updates the 2003 Technical Memorandum; it will inform revisions of the 2003 Wind/Bighorn River Basin Plan and the 2007 Wyoming Framework Water Plan. It presents a new compilation of available information on the groundwater resources of the WBRB. While original maps and tables were developed for this memorandum, no original investigations were performed.
