A proposed streamflow-data program for Pennsylvania

Regional analysis of the effects of land use on stream-water quality; methodology and application in the Susquehanna River Basin, Pennsylvania and New York

“…Area of lakes and ponds (STOR), in percent of drainage basin, determined from l:24,000-scale topographic maps, Darmer (1970), and Page (1970).…”

“…Main channel slope (SLOPE), in feet per mile, determined from elevations at the 10-and 85-percentiles of the distance along the channel from the gaging station to the divide (Benson, 1962). Data sources are Darmer (1970), Page (1970), and l:250,000-scale topographic maps.…”

“…Mean minimum January temperature (MINJAN), in degrees Fahrenheit, from Page (1970), Darmer (1970), a map for New York prepared by the NOAA (1972, p. 21), and a map for Pennsylvania prepared by the USGS office in Harrisburg based on 1931 to 1952 temperature records (H. Flippo, personal commun. ).…”
