We estimate the economic benefits of water quality improvements for recreational users of lakes, rivers and coastlines in six northeastern states. The benefits are measured using separate travel cost random utility maximization models for fishing, boating, swimming, and viewing. All models are for day-trip recreation. The models are estimated using data from the 1994 National Survey of Recreation and the Environment and from water quality modeling simulations of the National Water Pollution Control Assessment Model. We consider several scenarios for water quality improvements and estimate annual benefits in the region due the Clean Water Act to be near $100 million per year.
