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.
