Dams per 100 Square Miles


Dams per 100 Square Miles

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 2015, Berks County contained 3.6 dams per 100 square miles, for a total of 31 dams in the county. This is a slightly higher concentration than Pennsylvania on average, which has 3.4 dams per 100 square miles, and a much higher concentration than the country as a whole which has an average of 2.6 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 (24), Lebanon (13) and Lehigh (11) counties. It had far fewer dams than Chester (43) and Schuylkill (54) counties. When considered in terms of the size of the county, Berks had a similar rate of dams per 100 square miles to Lebanon (3.6) and Lehigh (3.2). Berks had fewer dams per 100 square miles than Chester (5.7), Montgomery (6.0) and Schuylkill (6.9). Lancaster County (with a rate of 2.5) had the lowest rate.

Notes about the data

No information about which dams are considered hazardous is made available due to terrorism concerns. Data for this indicator is updated every two years and is next expected to be released in 2018.
