Loudoun County Stream Assessment 2009
In early 2009, Loudoun County contracted with an environmental consulting firm to have assessments conducted on streams in the county as part of the Loudoun County Water Resources Monitoring Program
The stream assessment project provides information on the general
health of the streams and also identifies the extent of perennial
streams (those having flows all or most of the time versus intermittent
streams that have flows only after rainfall or during wet periods).
The project is partially funded by a grant from the U.S.
Environmental Protection Agency (EPA) and was completed in October 2009.

The State of Loudoun Streams: 2005
The State of Loudoun Streams: 2005 report provides baseline water quality data and assessments of current conditions in Loudoun County streams. These data are taken from stream monitoring reports and water quality studies prepared by government, regional, county, and citizen groups. While much data have been collected and several reports prepared on individual streams, this report provides comprehensive analyses of data from several sources that cover the major streams in Loudoun County. The 2005 report updates the State of Loudoun Streams: 2002 report prepared by Loudoun Watershed Watch.
The assessments of
watershed conditions are based on analyses of stream habitat, aquatic
insect communities, and physical and chemical data collected by government
and citizen groups. This is the first time that monitoring data from
state, regional, local, and volunteer groups have been integrated into one
comprehensive report on Loudoun streams.
A baseline report provides a point of reference on the severity of
degradation in monitored streams. The baseline data can help county
officials prioritize areas with the greatest needs, and can be used by
county planners applying Loudoun's policies that protect stream corridors.

Comprehensive Monitoring Plan
Stream monitoring by state and local government, and citizen watershed organizations plays a critical role in water resource protection and the development of watershed management plans. Monitoring is needed not only to provide baseline data, but also to assess stream health, identify stream degradation problems, and to assess stream protection and restoration activities. Stream monitoring data also provide an important component to watershed management plans. These needs are of increased importance as Loudoun County grows at an unprecedented rate. The county needs a revised strategy that better organizes state and local monitoring efforts.Click here to download a copy (770 KB Adobe format)
