Dam Safety
Dam & Levee Information
Indiana is home to more than 1,300 dams, each playing a critical role in flood control, water supply, recreation, and more, but they also come with serious safety considerations. The Indiana Department of Natural Resources (DNR) actively monitors and regulates these structures through its Dam Safety Program, ensuring they are properly designed, maintained, and inspected. Understanding how these systems work – and what happens when they fail – is key to protecting communities across the state.
From hazard classifications to detailed flood risk mapping, the DNR provides valuable tools and insights that help communities prepare for and respond to potential emergencies. Whether you’re a local official, property owner, or simply curious about infrastructure in your area, this page offers an inside look at how Indiana manages dam safety and reduces risk – making it well worth a closer look: DNR: Water: Dams & Levees
Low-Head Dams
What looks like a calm, harmless stretch of river can hide one of the most dangerous hazards on Indiana’s waterways. This page reveals the hidden risks of low-head dams (often called “drowning machines”) explaining how their powerful, circulating currents can trap even strong swimmers and experienced paddlers. You’ll also find practical tips on how to spot these hard-to-see dangers, avoid them entirely, and what to do in an emergency – knowledge that could quite literally save a life: DNR: State Parks: Low Head Dams
Dam Safety Toolbox
The Association of State Dam Safety Officials (ASDSO) Dam Safety Toolbox serves as a repository for current guidelines and recommendations related to dam safety. You can learn more about the Dam Safety Toolbox here: ASDSO Dam Safety Toolbox
Dam Breach Inundation Layer
The Dam Breach Inundation layer provides the projected inundation area downstream of dams located in Indiana due to potential breach failure of the dam structure. The Indiana Department of Natural Resources would like you to know that the information provided is for general awareness and may not always be accurate or up to date, so always verify details: DAM Breach Inundation Area
