One criticism of using reservoirs for irrigation is the impact on local ecosystems and biodiversity. Reservoirs often require the flooding of large areas of land to create the necessary water storage capacity. This can lead to the destruction of natural habitats, including forests and wetlands, which are crucial for many plant and animal species. The creation of reservoirs can result in the loss of valuable ecosystems, displacement of wildlife, and disruption of natural waterways. Additionally, the altered flow pattern of water in reservoirs can lead to changes in water temperature, oxygen levels, and sediment deposition, which can further harm aquatic ecosystems and the species relying on them.
