VII. Reports

A. Report from Engineering Consultant – Tom Harder, ALDA Engineering

Mr. Harder presented a Powerpoint on Developing Methodology to
Account for Return Flow Recharge. He pointed out that return flow is
included in the water budget for the Beaumont Basin and is part of the
safe yield. He addressed the interest in crediting return flow that occurs
on overlying appropriator service areas to the appropriators; a parcel-
by-parcel estimate would need to be made.

Mr. Harder also presented information on basin losses.

Mr. Harder reported on comment received regarding the report on basin
losses. The City of Banning asked about recharge, and Mr. Harder noted
the bulk water in question recharged at the Noble Creek facility is
accounted for in the model; recharge elsewhere in the basin is not. The
purpose of the memo was to provide a magnitude of losses and what
affects losses, then develop a method to account for the loss. Additional
analysis can be done.

Another question, stated Mr. Harder, was whether irrigation return flows
should be accounted for and if it impacts losses. He said they should,
but they are minor. As return flows increase in the basin, those losses
will increase.

The final question, Mr. Harder noted, was regarding wells outside the
adjudicated area and whether those affect the losses. There is some
hydrologic separation between the Beaumont Basin and the Banning
