Control Structure Stoplog Settings

Find the stoplog settings for inline water level control structures used for edge-of-field conservation drainage practices, such as bioreactors, saturated buffers, and controlled drainage. The tool is designed for control structures that use a combination of 7-inch and 5-inch stoplogs to control the outlet level. For more information on managing control structures, see Bioreactor and Saturated Buffer Management on the Conservation Drainage Network website.
