Leaser Lake, reservoir in Lynn Township, Lehigh County, Pennsylvania
Leaser Lake is a man-made reservoir in Lynn Township, Pennsylvania, covering about 117 acres (47 hectares). The lake was created by an earthen dam on Jacksonville Branch creek and reaches depths of around 45 feet (14 meters), providing habitat for multiple fish species and surrounded by a 540-acre park with trails and natural areas.
The lake opened to the public in 1971 as a recreation area. The dam has experienced seepage problems since construction, requiring repairs in 1991, 1999, and again from 2008 to 2009, with the reservoir finally reaching full capacity in spring 2015.
The lake is named after Frederick Leaser, a Revolutionary War patriot whose story remains part of local memory. A monument here honors his role in protecting the Liberty Bell, and this historical connection gives visitors a sense of place rooted in the region's past.
A flat, easy trail circles the entire lake and takes about two hours to walk, with picnic tables and rest areas along the way. Only small boats with electric motors are permitted, and gasoline engines are prohibited to keep the water calm and clean. The park offers parking, restrooms, and accessible docks for visitors.
Frederick Leaser, the man for whom the lake is named, helped transport the Liberty Bell from Philadelphia in 1777 to save it from British forces. Few visitors realize that this quiet water body is connected to one of America's most important historical symbols through its namesake's role in preserving it.
