Increasing population, urbanization and planned development with in the next few years by the State University of New York (SUNYAB), Urban Development Corporation (UDC), New York State Department of Transportation (DOT), and Planned Environment Systems incorporated require efficient use of water resources in the Ellicott Creek Basin. There is, therefore, an increasing demand for water supply, flood control, outdoor recreation, water quality, preservation of the natural environment, and fish and wildlife conservation. The report is a restudy of a survey report completed in 1970 that recommended construction of a dam and multi-purpose reservoir at Sandridge with downstream channel improvement. The present study considers current and future problems, desires and needs of residents and other interests in the Ellicott Creek Basin, projects, future needs, and recommends the most viable solution to meet the significant short and long term water resources and related needs.
