Merritt Lake, also known as Grant Ave Bridge, is a Federal-owned recreational water resource located in Leavenworth, Kansas. This man-made lake, completed in 1860, serves multiple purposes including fish and wildlife pond and recreation. With a dam height of 20 feet and a hydraulic height of 22 feet, Merritt Lake offers a serene escape for water resource and climate enthusiasts to enjoy its 7-acre surface area surrounded by a drainage area of 280 acres.

Managed by the US Army, Merritt Lake boasts a low hazard potential and very high risk assessment rating. Despite its age, the dam's condition assessment is not available, and the last inspection was conducted in 2016. The controlled spillway and 55-acre-feet of storage capacity ensure the safety and stability of the dam structure. With its historical significance and recreational offerings, Merritt Lake is a must-visit destination for those interested in water resources and climate preservation efforts in the heart of Kansas.
