comments for your consideration. Please note that our initial comments are based on
our current knowledge of the basin only as no additional calculations or modeling runs
have been conducted.

groundwater storage in the Beaumont Basin by Non-Appropriators. The application
by SGPWA addresses each of the four sections outlined in the resolution.

ft. In addition, there is a storage agreement with Morongo Band of Mission Indians,
a Non-Appropriator, for 20,000 ac-ft. for an overall total of 280,000 ac-ft. in storage
agreements. The request by SGPWA to store up to 10,000 ac-ft. in the basin, if

ft.
3.- According to the application, the SGPWA will like to construct the spreading facility
and take advantage of additional water available through the State Water Project in
