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. 

While raw data are available for analysis-driven activities, LACA publishes our monitoring results using screenshots generated from Google Maps.  Maps for WQ monitoring activities in 2020 will be added to the website when we are able to collect samples this year.  Maps for cyanobacteria monitoring activities in 2020 are provided below and are updated after each weekly monitoring session. 

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.

LACA's data and maps are provided on pages for the following four components of our program:

1. Water quality monitoring that LACA conducts four times each year for parameters such as Total Phosphorus, E.coli bacteria, Dissolved Oxygen and pH.  
2. Cyanobacteria data and maps for the lower and middle lake areas (from the dam to the splits)
3. Cyanobacteria data and maps for the upper lake areas (North Anna River and Pamunkey Branches)
4. Cyanobacteria data and maps for the Waster Heat Treatment Facility (WHTF)
