In early 2002, LACA created a Volunteer Water Quality Monitoring Program with a mandate to begin water quality monitoring needed to assess the lake’s water quality. There were several issues being analyzed and discussed at this time. First, there were assessments developed by State agencies reporting levels of E.coli bacteria that caused many of the streams leading into Lake Anna to be declared as impaired. In addition, the assessments also listed several streams as impaired due to high acid levels. The LACA Water Quality Monitoring Program was established to specifically determine whether the E.coli and acid conditions which cause the tributary impairments were affecting the lake itself.
The LACA Water Quality Monitoring Program began monitoring in March 2002 at 13 sites on the lake in order to provide indicators of whether E.coli and acidic impairments had intruded into the lake from the impaired streams identified in the State assessments. This monitoring also provided indications of dissolved oxygen and nutrient (phosphorus) status as well as water clarity.
Monitoring at over 30 sites is now carried out jointly with the Commonwealth’s Department of Environmental Quality (DEQ) under a joint Memorandum of Agreement (MOA) that was initiated in 2002. The current MOA with DEQ is available in the Water Quality Committee Library.
The Water Quality Committee is chaired by Mike Gelber and co-chaired by Harry Looney. Please reach out to us if you have any questions, concerns or ideas on improving water quality at Lake Anna.
LACA Input to DEQ on Prioritization of Impaired Waters in the Lake Anna Watershed
The Virginia Department of Environmental Quality (DEQ) is implementing the national vision which promotes the prioritization of impaired waters for Total Maximum Daily Load (TMDL) or TMDL alternative development. Through this process, DEQ will identify specific water quality impairments and other strategic measures in a prioritized list of waters for TMDL or TMDL alternative development in the 2022-2028 time frame. As part of the process, DEQ requested public input on their prioritization process. Specifically, DEQ requests written or electronic input from interested persons on 1) impaired waters to prioritize for TMDL or TMDL alternative development (i.e., specific waterbodies) and 2) factors or other information DEQ should use to prioritize impaired waters for TMDL or TMDL alternative development.
A TMDL is a watershed cleanup plan required by the Clean Water Act and the State Water Control Law for all waters that do not meet water quality standards. These waters are polluted and called “impaired.” TMDLs determine the amount, or load, of a pollutant that a waterbody can receive and still meet water quality standards. TMDL alternatives are watershed cleanup plans typically developed when the cause of a water quality problem is clear and the analysis required to develop a TMDL is not necessary for restoration efforts.
The opportunity to provide input is open through Monday, October 5th, 2020. LACA prepared a response and sent it to DEQ on Saturday, October 3rd. A copy of the letter can be read at this link. If you are interested in sending a personal input you may write directly to the DEQ point of contact listed below. A copy of the draft Integrated Report that lists current impaired waters is available on the DEQ website at this link.
