What does this measure?

The number of dams per 100 square miles.

Why is this important?

While dams can provide benefits such as economic activity, renewable power, and flood control, many dams are rapidly aging and come with significant costs. Dams can contribute to water pollution of their related watershed, as well as impacting local environments and habitats. Additionally, as dams age, their infrastructure can weaken and increase the chance of failure, potentially endangering human life and property. The more dams in an area, the more monitoring and infrastructure investment they require to ensure the safety of those in the surrounding areas. Pennsylvania is one of seven states in the U. S. in which high hazard potential dams count for more than half of the dams in the state.

How is our county performing?

As of 2018, Berks County contained 4.3 dams per 100 square miles, for a total of 37 dams in the county. This is a slightly higher concentration than Pennsylvania on average, which has 3.3 dams per 100 square miles, and a much higher concentration than the country as a whole which has an average of 2.4 dams per 100 square miles. Berks County contains 2% of the total dams in the state.

Compared to neighboring counties, Berks had a larger number of dams overall than Montgomery (29), Lancaster (22), Lebanon (14) and Lehigh (11) counties. It had far fewer dams than Chester (43) and Schuylkill (55) counties. When considered in terms of the size of the county, Berks had a similar rate of dams per 100 square miles to Lebanon (3.9). Berks had fewer dams per 100 square miles than Chester (5.7), Montgomery (6.0) and Schuylkill (7.0). Lancaster County (with 2.2 dams per 100 square miles) had the lowest rate.

Notes about the data

A well maintained and inspected dam is high hazard potential if failure would result in loss of at least one life. Click to learn more about dams. Data for this indicator are released annually in December.
