Impacts to Historic Properties in Drawdown Zones at Corps of Engineers Reservoirs

This report deals with the nature and occurrence of impacts to historic properties along the shorelines and in the drawdown zones of Corps of Engineers reservoirs. It presents the survey questionnaire responses obtained from all Corps Districts and describes the management practices observed in field visits to nine Corps reservoirs.
