The Hudson River basin includes streams draining the Hoosic River (205 square miles), Kinderhook Creek (20.9 square miles), and Roeliff Jansen Kill (13.3 square miles) basins in western Massachusetts, eastern New York, and southern Vermont. Drainage areas, using the latest available 1:24,000 scale topographic maps, are re-computed for data-collection sites and computed for the first time for streams draining greater than 3 square miles. Basin characteristics representing 14 commonly used indices to estimate various streamflows are presented for the five gaged streams in the Hoosic River basin. Streamflow characteristics, representing statistics computed using a new data base with records through 1979, include annual and monthly flow statistics , duration of daily flow values, and the annual 7-day mean low flow at the 2-year and 10-year recurrence intervals. Seven-day low-flow statistics are presented for 21 partial-record sites. The procedures used to determine the hydrologic characteristics are summarized. This gazetteer of hydrologic characteristics will aid in the planning and siting of water-resources-related activities and will provide a common data base for governmental agencies and the engineering and planning communities.
