MODEL RESULTS

Results of the model simulations for nine representative control points are
presented in this section (table 6). Four of the controls points are at or near
streamflow-gaging stations, which permits a comparison with actual conditions in
the basin. The model results showing monthly values of mean, median, and 80-per-
cent exceedence flows are presented in five tables for each control point. The
first table presents the results of historical conditions with and without trans-
mountain diversions and, where appl icable, a summary of the streamflow records for
water years 1927-76 from the streamflow-gaging station at or near the control
point. The remaining four tables present the results of the 25-, 50-, 75-, and
100-percent water-use allocations of the agricultural diversions with and without
the transmountain diversions. For all tables, monthly streamflow statistics less
than the corresponding values for simulated historical conditions are underscored
to indicate reductions in flow.
