Beaverdam Branch


The 60 square mile Beaverdam Branch Watershed is located predominantly in western Blair County, with a very small portion of its headwaters originating in Cambria County to the west. The watershed crosses multiple municipal boundaries; it takes up large percentages of the City of Altoona (60%), Logan Township (50%), Allegheny Township (50%), and nearly all of Hollidaysburg Borough. The watershed contains portions of State Game Lands 198 and 279. Forested lands and urban development are the two biggest land uses in the watershed.

The Beaverdam Branch, namesake of the watershed, flows about six miles from its headwaters to its confluence with the Frankstown Branch of the Juniata River. The entire length of the Beaverdam Branch is listed as impaired, as well as three of its tributaries: Mill Run, Sugar Run, and Burgoon Run. These three tributaries all flow into Beaverdam Branch at its headwaters.

Drinking Water Supplies in this Watershed

Five reservoirs are located in the Beaverdam Branch Watershed. Three of them – Kittanning Point, William L Cochran Impounding Dam, and Lake Altoona are located near the Horseshoe Curve. These reservoirs are filled by Glenwhite Run, Kittanning Run, and Scotch Gap Run (after leaving Lake Altoona the stream is called Burgoon Run). The other two reservoirs – Mill Run and Little Alegheny are located along Mill Run, which is north of Scotch Gap Run. These reservoirs are operated by Altoona Water Authority, which provides clean drinking water to thousands of people in Blair County.
