Lake Louise (Pennsylvania)

Lake Louise is a lake in Luzerne County, Pennsylvania, in the United States. It has a surface area of approximately 67 acre on The National Map and is located entirely in Franklin Township. The lake is dammed by the Lake Louise Dam, which is in poor condition, as of 1980. Lake Louise is situated on Sutton Creek and drains an area of 2.69 sqmi. As of 1980, its watershed is mostly forested. The Lake Louise Lake Association was given a Growing Greener mini-grant in 2012.

Geography, geology, and watershed
The main inflows to Lake Louise are Sutton Creek and two unnamed streams. The main outflow is Sutton Creek. The lake has an elevation of 1083 ft above sea level. Under normal conditions, the lake has an area of 56 acre, a volume of 193 acre.ft, and a length of 4000 ft. However, the maximum storage capacity is 705 acre.ft. The lake is 4 mi upstream of the Susquehanna River.

Lake Louise is dammed by the Lake Louise Dam. As of 1980, this dam is in poor condition, with a spillway capable of handling 45 percent of a probably maximum flood. It was classified as an "unsafe non-emergency dam". The dam is an earthfill dam with a height of 16 ft, a length of 210 ft, and a width of 26 ft at the top.

Lake Louise is in the Glaciated Low Plateaus section of the Appalachian Plateaus physiographic province. The main rock formation underlying the lake is the Devonian-age Susquehanna Group, which consists of conglomerate, siltstone, sandstone, and shale.

The watershed of Lake Louise has an area of 2.69 sqmi. As of 1980, the watershed of Lake Louise is mostly forested. Most slopes in the watershed are gentle or moderate.

Lake Louise is entirely within the United States Geological Survey quadrangle of Center Moreland.

Hydrology
In October 2007, the concentration of nitrate/nitrogen at the inlets to Lake Louise ranged from 0.19 to 0.33 mg/L. In November 2009, the concentration ranged from 0.10 to 0.46 mg/L and in May 2011, the concentration ranged from 0.09 to 0.33 mg/L. At the outlet of Lake Louise, the concentrations on those three dates were 0.19 mg/L, 0.12 mg/L, and 0.24 mg/L, respectively. For comparison, healthy lakes generally have concentrations of less than 0.05 mg/L in the summertime.

In October 2007, the concentration of phosphorus at the inlets to Lake Louise ranged from 0.61 to 1.62 mg/L. In November 2009, the concentration ranged from 0.04 to 0.99 mg/L and in May 2011, the concentration ranged from 0.04 to 0.53 mg/L. At the outlet of Lake Louise, the concentrations on those three dates were 0.00 mg/L, 0.29 mg/L, and 0.59 mg/L, respectively. For comparison, a phosphorus concentration of more than 0.03 mg/L indicates a eutrophic lake.

History
Lake Louise was entered into the Geographic Names Information System on August 2, 1979. Its identifier in the Geographic Names Information System is 1199089.

In 2012, the Lake Louise Lake Association was awarded a Growing Greener mini-grant for sediment removal, shoreline stabilization, riparian buffer establishment, and invasive species control on Lake Louise.
