Clark County 16 is a gravity dam located in Clark County, Wisconsin, on Hay Creek, completed in 1935 for irrigation purposes. With a structural height of 9 feet and a length of 50 feet, the dam has a storage capacity of 110 acre-feet and serves multiple purposes such as irrigation, recreation, and water supply. Despite its low hazard potential, the dam's condition assessment is poor, indicating a need for maintenance and potential improvements to ensure its long-term reliability and safety.

This dam is under state regulation by the Wisconsin Department of Natural Resources (WIDNR), with state permitting, inspection, and enforcement in place. Although the last inspection was conducted in 2012, the dam's condition was assessed as poor in 2017, highlighting the need for regular maintenance and assessment to mitigate any risks associated with its operation. The dam's maximum discharge capacity is 687 cubic feet per second, with a controlled spillway type in place to manage excess water flow during high water events.

Despite its age and condition assessment, Clark County 16 continues to play a crucial role in providing irrigation water to the surrounding area. As a key water resource in the region, it is essential to ensure its proper maintenance and operational readiness to meet the water supply needs of the community while also addressing any potential safety concerns. Climate enthusiasts and water resource managers should keep a close eye on this dam to ensure its continued functionality and safety in the face of changing climate conditions and evolving water resource management practices.
