The hydrology of the area is primarily influenced by precipitation and surface runoff, with occasional flooding during heavy rain events. The region experiences a moderate amount of snowfall during the winter months, with an average snowpack depth of 5-10 inches. Surface water quality in the watershed is generally good, with low levels of pollutants and contaminants. Interesting climatic facts include the region's relatively mild summers and cold winters, with average temperatures ranging from 20-85 degrees Fahrenheit. Trends in precipitation and temperature in recent years suggest an increase in extreme weather events, including heavy rain and snowfall, as well as more frequent and intense heat waves.
