Vorster 1985:

Peter Vorster's MS thesis describes a Fortran computer model of the water flows in the Mono Basin.
The model is quite well documented, and its historical results have been checked against the history on Mono Lake.
The system dynamics model in Chapter 5 is adapted from Peter's excellent work.
The standard reference in the book is Vorster 1985:

Vorster, P. A Water Balance Forecast Model for Mono Lake, California,
US Forest Service, Berkeley, California Box 245, Berkeley, CA 94201.

However, the thesis is also available as PDF files
at the Mono Basin Clearing House (as of Oct 2009)
