F.3: Preliminary Hydrology Estimate for Carlo Creek
Existing hydrology information collected by the U.S. Geological Survey for rivers and streams in
the general vicinity of Carlo Creek was reviewed to develop preliminary estimates of hydrology
for Carlo Creek. Figure 1 presents normalized stream flow for several gauged rivers in the Carlo
Creek region, and estimated hydrology for Carlo Creek. The preliminary design flow of 40 cubic
feet per second (cfs, equal to 2.6 cfs per square mile of basin area) is also shown on Figure 1.
The plant capacity factor is estimated at 45%.
