Hydrologic Drought in Virginia
March 8, 2002 (Tables)
Data are provisional and subject to revision. Streamflow values are in cubic feet per second
(cfs). The normal range of flow is defined as flows between those equaled or exceeded 75% of
the time and those equaled or exceeded 25% of the time on the flow duration
curve. A flow
duration curve shows the percentage of time a particular flow occurred during the available
period of record. The last column in the table relates the current flow to the monthly flow
duration curve for that site.
