Natural Resources Conservation Service CONSERVATION PRACTICE STANDARD STRUCTURE FOR WATER CONTROL Code 587 (No.) DEFINITION A structure in a water management system that conveys water, controls the direction or rate of flow, maintains a desired water surface elevation, or measures water. Apply this practice as a component of a water management system to control the stage, discharge, distribution, delivery, or direction of water flow. This practice applies to a permanent structure needed as an integral part of a water control system to serve one or more of the following functions: Convey from one elevation to a lower elevation within, to, or from a water conveyance system such as a ditch, channel, canal, or pipeline. Typical structures include drops, chutes, turnouts, surface water inlets, head gates, pump boxes, and stilling basins. Control the elevation of water in drainage or irrigation ditches. Typical structures include checks, flashboard risers, and check dams. Control the division or measurement of irrigation water. Typical structures include division boxes and water measurement devices. Keep trash, debris or weed seeds from entering pipelines. Typical structures include trash racks and debris screens. Control the direction of channel flow resulting from tides and high water or backflow from flooding. Typical structures include tide and water management gates. Control the water table level, remove surface or subsurface water from adjoining land, flood land for frost protection, or manage water levels for wildlife or recreation. Typical structures include water level control structures, flashboard risers, pipe drop inlets, and box inlets. Convey water over, under, or along a ditch, canal, road, railroad, or other barriers. Typical structures include bridges, culverts, flumes, inverted siphons, and long span pipes. Modify flow to provide habitat for fish, wildlife, and other aquatic animals. Typical structures include chutes, cold water release structures, and flashboard risers. Provide silt management in ditches or canals. Typical structures include sluice and sediment traps. Supplement a resource management system on land where organic waste or commercial fertilizer is applied. Create, restore, or enhance wetland hydrology.
