How can large structure dams be identified?

Large structure dams can be identified primarily by their powerhouses and spillways. These components are integral to the dam's function. The powerhouse is where electricity is generated, allowing the dam to serve as a source of hydroelectric power. The spillway is designed to safely release excess water from the reservoir, which is crucial for managing water levels and preventing overflow or potential flooding.

While water level, operation hours, and recreational facilities might provide additional information about a dam, they do not definitively identify it as a large structure. Identifying a dam by its critical operational features ensures a clear understanding of its capacity and role within the water management system. This focus on tangible structural components is essential for distinguishing large dams within a broader context.
