Outdoor recreation is a major, growing use of water resources in the United States. The economic effects of expenditure by visitors to three recreational river sites on local economies surrounding the sites were estimated using an input-output model (IMPLAN). Expenditure data were from the Public Area Recreation Visitors Study (PARVS). Results indicate that visitor spending stimulates a consideratble amount of economic activity and growth in local economies. Economic effects include increases in total gross output ranging from $2.6 million to $13.4 million, increases in total income ranging from $1.2 million to $5.6 million, and increases in employment ranging from 60 to 292 jobs.

The events of September 11, 2001 caused a shift in thinking about public access at hydro facilities, but the need to provide recreation remains. A Federal Energy Regulatory Commission team works to help owners keep their projects secure while still providing essential public access.
