Impaired Water Notes
Correction - should have been listed previously instead of Ranch Creek. Change advice from general and exceptions for largemouth bass all size and black crappie and bluegill TO general and exceptions for largemouth bass >21�, black crappie and bluegill. The 2012 data for bluegill and largemouth bass suggest the mercury concentrations may be less than prior years� results. However, one more additional low sampling event is needed for bluegill and largemouth bass before removing exception. Both 2012 bluegill and largemouth bass results are on the cusp of falling under the general advisory but two years of lower mercury concentrations are needed and 2012 black crappie mercury concentrations still exceed exception criteria.
