Lake Vaquero in Shawnee, Kansas, is a privately owned recreational reservoir completed in 1963. With a dam height of 32.5 feet and a storage capacity of 778 acre-feet, this earth dam on Shunganunga Creek provides ample opportunities for water-based activities and outdoor leisure. The reservoir covers a surface area of 30.3 acres and serves as a popular destination for residents and visitors seeking a scenic retreat in the heart of Topeka.

Managed by the Kansas Department of Agriculture, Lake Vaquero is subject to state regulations and inspections to ensure its safety and functionality. The dam's spillway, although uncontrolled, has a width of 10 feet, mitigating the risk of flooding during periods of high discharge. Despite being classified as having a high hazard potential, the dam is currently assessed as satisfactory, with moderate risk management measures in place to address any potential issues that may arise. With its tranquil surroundings and recreational offerings, Lake Vaquero stands as a testament to the harmonious coexistence of water resources and climate enthusiasts in the region.
