USGS Water-Year Summary 2023

03513000 TUCKASEGEE RIVER AT BRYSON CITY, NC

LOCATION - Lat 35°25'39", long 83°26'49" referenced to North American Datum of 1983, Swain County, NC, Hydrologic Unit 06010203, on left bank 400 ft downstream of bridge on Secondary Road 1364, Everett Street, in Bryson City, 0.6 mi downstream of Deep Creek, and at river mile 12.6.

DRAINAGE AREA - 655 mi². (measured by TVA from topographic maps, scale, 1:24,000). Basin is made up of steep wooded slopes; small farms, towns and communities in the valleys, moderately populated; several lakes and reservoirs are located in upper reaches of basin. Average annual rainfall is 50-60 inches.

REVISIONS HISTORY - WSP 523: 1916, daily discharges. WSP 823: Drainage area. WSP 1306: 1898-1929, 1933-34, maximum discharges. WSP 1336: 1898, 1900-1906, 1908-1915, 1917-1929, 1932, 1934, maximum discharges; 1906, 1915, 1916-1918, daily discharges.
