LAKE ANNA WATER QUALITY MONITORING:
 
Measuring O2 Levels Charlie Hofmann and Carl Groth enter volunteer data into a computer database, and email the collated data to each volunteer team for review and validation. The laboratory analysis results are received from the state lab after several days, and those data are entered into the database. All data are then sent to DEQ for consolidation with data from other citizen volunteers and state monitoring teams. This data is used by DEQ and the U.S. Environmental Protection Agency to assess the quality of our watershed’s and Virginia’s waters, and to take appropriate follow-up action if concerns arise over the data.
 
Soil and Water Conservation Society These Lake Anna Civic Association (LACA) volunteers have been awarded the Virginia Chapter of the National Soil and Water Conservation District’s Merit Award for their work in protecting the watershed. The LACA Water Quality Program has received funding since 2000 from Virginia’s DEQ and Department of Conservation and Recreation (DCR), Louisa and Spotsylvania counties, Dominion Power, Inc., and the Chesapeake Bay Program. The Lake Anna Water Quality Program is cited in the York Watershed Newsletter as one of two programs in the York Watershed undertaking major watershed management planning efforts.
 
LACA WATER QUALITY MONITORING RESULTS:
 
Virginia’s Department of Environmental Quality (DEQ) LACA volunteers have been monitoring Lake Anna’s waters since February 2001. LACA joined with Virginia’s Department of Environmental Quality (DEQ) in 2002 to jointly monitor the lake under a cooperative Memorandum of Agreement (MOA). This MOA was the first such agreement between DEQ and a citizen monitoring group, and has served as the model for subsequent agreements with other citizen monitoring groups in Virginia.
 
Fig.1 Water Map DEQ’s baseline assessment in 2002 of Virginia’s water quality revealed that there are 11 water segments in our Lake Anna Watershed which are “impaired.” See Figure 1 for the DEQ map of impaired segments, and the location of LACA volunteer monitoring sites. Eight segments of streams above the Lake are impaired with fecal coliform bacteria. Our monitoring on the Lake has not indicated that these bacteria have invaded the Lake on a regular basis. However, we have found bacteria at significant levels on two occasions after major rains, the most recent occasion being in late June, 2003. Subsequent monitoring at the same sites on 1 July by the Department of Environmental Quality did not indicate significant levels of bacteria.
