Water Supply Outlook A seasonal volume forecast, generally for a period centered around the time of spring snowmelt (e.g., April-July).
Palmer Drought Severity Index(Abbrev. PDSI) - an index used to gage the severity of drought conditions by using a water balance equation to track water supply and demand. This index is calculated weekly by the National Weather Service.
event or several larger radio events (10cm) per day (Class M Flares)Active Conservation StorageIn hydrologic terms, the portion of water stored in a reservoir that can be released for all useful purposes such as municipal water supply, power, ...
For instance, researchers can identify and predict natural river-flow variability to assist engineers designing irrigation and water supply systems and make computer studies of pollutant and contaminant dispersion.
If no flooding has occurred within the past month, a climatic summary of the past month can be included as well as other interesting non-flood events, such as water supply, ice jams and the occurrence of drought.
The community has only 30 days' water supply left in its two reservoirs. ''During the period of 1981, Pine Grove had to go to water rationing.
