What it concludes

Crest gates provide control over upstream water levels and are often used where water levels need to be kept within a narrow range.
Radial gates are the most widely used spillway gates at large dams due to their reliability and ability to handle immense forces while pivoting.
Bear-trap gates, while offering the benefit of operating without external power, are difficult to inspect, maintain, and prone to silting.
Neglecting water infrastructure maintenance can lead to catastrophic gate failures, such as the 2019 failure at Dunlap Dam.
