Freese and Nichols joins several national organizations today to commemorate National Dam Safety Awareness Day.

There are more than 90,000 dams across the United States, many of which are vital to the nation’s infrastructure by providing drinking water, holding back flood waters, storing water to irrigate crops, providing recreation opportunities, and controlling rivers for navigable transportation. In addition, dams provide nearly half of the nation's clean, renewable electricity through hydropower generation.

Yet dams...
