Represa is a term that generally refers to a dam or reservoir, which is a structure built to hold back water. These structures are often used for various purposes, including water supply, irrigation, flood control, and hydroelectric power generation. Represas can vary in size and design, depending on their intended use and the geographical features of the area. In many regions, represas play a crucial role in managing water resources. They help regulate river flow, store water for dry seasons, and provide recreational opportunities such as fishing and boating. Additionally, represas can support local ecosystems by maintaining water levels in surrounding habitats.
