Guidance Document Information
||Monitoring and Assessment of Lakes and Reservoirs
||This guidance supersedes all agency Lake Monitoring Guidance prior to 2009 (GM02-2004) and provides direction to agency staff on how to implement lake/reservoir water quality monitoring. Significant updates to this guidance since 2002 include implementing the new surface water quality standard regulation (9 VAC 25-260-187), effective as of August 14, 2007, which added nutrient criteria for significant man-made lakes and reservoirs and the two natural lakes in Virginia. Current Triennial Review updates to this Standard include the definition of lacustrine zone, which allows for dissolved oxygen sampling throughout the lake and adds several additional lakes (6) to the significant lakes list.
