Station description and summary of hydraulic data, East Branch Delaware River at Margaretville, N.Y. Location.--Latitude 4208'41" N., longitude 7439'14" W., Delaware County, on right bank at downstream side of bridge on Fair Street at intersection with Main Street at Margaretville, 0.2 mi upstream from unnamed tributary, and 1.6 mi downstream from Dry Brook. A 3-section, 354-ft-long reach; section 1 is 190 ft downstream from bridge on Fair Street. USGS station-identification number.--01413500. Drainage area.--163 mi2. Bed material.--Gravel and cobbles. Intermediate diameter dx = 0.28 ft and dM = 0.44 ft. Minimum diameter d5Q = 0.09 ft. Bank description.--Both banks have dense brush with a few sparsely spaced trees, mostly 1.0 to 1.5 ft in diameter.
