Mize Lake, located in Lenexa, Kansas, is a local government-owned reservoir that serves multiple purposes, including flood risk reduction, recreation, and other uses. Built in 2005 by HNTB Corporation, this earth dam stands at a height of 31.6 feet and has a storage capacity of 191.8 acre-feet. With a surface area of 7.4 acres, the lake provides a tranquil environment for water resource and climate enthusiasts to enjoy various outdoor activities.

Managed by the Kansas Department of Agriculture, Mize Lake is regulated, permitted, inspected, and enforced by the state to ensure its safety and functionality.

The reservoir's location within the Kansas City District and its proximity to Cedar Creek make it an essential component of the local water infrastructure. With its ample storage capacity and strategic design, Mize Lake plays a crucial role in managing flood risks, providing recreational opportunities, and supporting the overall water resource management efforts in Johnson County, Kansas.
