CoCoRaHS Water Year Summary Reports


 

Hydrologists and climatologists often use the "Water Year" calendar for tracking water resources. While the definition may vary regionally, a common definition of "water year" is October 1 through September 30th. In the cool months, evaporation rates are very low, snow accumulates in cold regions, storms tend to be widespread, and most areas see accumulation of moisture in the soil. Then comes spring with it's accompanying snow melt and high runoff from mountainous regions and higher latitudes. The summer months bring high evaporation rates. Precipitation (much from thunderstorms) becomes much more localized. Soil moisture may be gradually depleted during summer as vegetation uses large volumes of water. Streams run slower and clearer.

CoCoRaHS recommends this water year calendar for tabulating precipitation amounts. If you are a CoCoRaHS observer, you can download the water year summary report for your station(s) from here or the "My Account" link in the top menu.
