Water Quality (WQ) and Cyanobacteria Data & MAPS

The Water Quality Committee maintains the current and historical WQ and cyanobacteria data collected by our volunteers.  The WQ raw data is available for public review at the Chesapeake Monitoring Cooperative (CMC) Data Explorer web site.  We also provide raw data files to government agencies, academia and civic organizations that request the data for their analyses. 

Requests for data files should be forwarded to the Water Quality Monitoring Program Project officer at harry.looney@lakeannavirginia.org.  Include full name, organization, email, phone number, data requested (parameters, dates, etc), a justification (how the data will be used) and if you would like approval to release the data to other agencies or in a formal report.

While raw data are available for analysis-driven activities, LACA publishes our monitoring results using screenshots generated from Google Maps.   See the links below for the various mapping files available for our members and anyone looking for Lake Anna water quality data.
