Walsh is a privately owned dam located in Juneau, Wisconsin, specifically in the city of WONEWOC. Built in 1976 by the USDA NRCS, this earth dam stands at a height of 27.5 feet and serves multiple purposes including fire protection, stock, and small fish pond. The dam has a normal storage capacity of 12 acre-feet and a maximum discharge of 60 cubic feet per second.

Despite its fair condition assessment, Walsh poses a high hazard potential, prompting the need for regular inspections which are conducted every two years. The dam, with a spillway width of 13 feet, is situated on the TR-BARABOO RIVER and has a drainage area of 0.2 square miles. Its associated structures are currently at zero, and the dam's risk assessment is categorized as moderate (3).

In the event of an emergency, the dam at Walsh does not have an Emergency Action Plan (EAP) prepared, implying the need for further risk management measures. The dam is regulated by the Wisconsin Department of Natural Resources (WIDNR) and falls under state jurisdiction for permitting, inspection, and enforcement. With its strategic location and significant impact on water resources, Walsh serves as a critical infrastructure for fire protection and ecological conservation in the region.
