Water birds

Related to water-level regulation

The management of dams and project construction and maintenance may necessitate modifications to water levels in reservoirs, ponds or other wetlands. For example, it may be required to remove beaver dams in order to regulate water-levels. Under such circumstances, project managers should determine whether waterfowl, waterbirds and/or other birds are nesting in or near the wetland, and avoid regulating water-levels that could result in flooding or drying out nests until the birds have raised their young. Water-level modifications may, for example, be scheduled prior to or after the breeding season.
