precipitation frequency climatology
and past storm patterns over the
basins. For each of these scenarios,
PMP was summarized by the gridded average over the sub-basins that
comprise the drainage area.
The following figures summarize
the sub-basin average PMP values
for each dam scenario. Scenario 1
(Figure 10) includes general storm
PMP for the 11 sub-basins upstream
of the Glenmore Dam (shown in
Figure 7).
Scenario 2 includes the 8 subbasins upstream of the SR1 Diversion
(shown in Figure 8). Figure 11 provides the general storm PMP values
for the drainage above the SR1 diversion. Figure 12 provides the local
storm PMP using the 1-hour Glen
Ullin, ND, June 1966 spatial redistribution. Table Figure 14 provides
the local storm PMP for the 31 square
kilometre drainage upstream from
the SR1 dam.
Scenario 3 is the 31 km² sub-basin
average local storm PMP (Figure 14)
upstream of the SR1 Dam (shown in
Figure 13).
