From June through October 2012 Maryland Department of Natural Resource (DNR) will be conducting a smallmouth bass angler survey on the Potomac River between Harpers Ferry and Seneca Breaks.
Information gathered from the survey will be used to help biologists track smallmouth bass population trends and gauge the effects of regulations.
The survey will collect basic fishing information from anglers via postage prepaid survey cards, which will be distributed to anglers on the river and at bass clubs.
In November, DNR will randomly draw 10 winners from the survey submissions who will each receive a $50 prepaid debit card.
