To keep the land behind the levees dry, the Districts manage a complex series of sloughs, pipes, and culverts that feed into pump stations and move water away from the managed floodplain into the Columbia River and lower reaches of the Columbia Slough. This work involves monitoring and maintaining pump stations, clearing debris and other blockages from the conveyance system, and attending to wildlife activity when necessary.
Pump Station Management
District employees operate and maintain a total of 12 pump stations. Nearly all pump stations are connected to a Supervisory Control and Data Acquisition (SCADA) system and three in-stream monitors (ISMs) that identify water elevations at specific points throughout the District’s drainage system. Via SCADA, District employees can monitor water elevations, check which pumps are running, weather conditions, and turn pumps on and off remotely.
Property owners or residents experiencing drainage issues may contact the District office at 503-281-5675.
Aquatic Herbicide Treatments and Mechanical Removal
To ensure conveyance, access, and flood storage capacity, aquatic weeds need to be maintained to allow for proper water flow and reduce the risk of internalize flooding behind the levees. MCDD conducts spot spray and mechanical removal techniques on Water Primrose (Ludwigia peploides montevidensis), Eurasian Watermilfoil (Myriophyllum spicatum and Parrot Feather (Myriophyllum aquaticum), which are considered noxious (harmful) aquatic weeds in the State of Oregon.
In all its vegetation management work, MCDD employees and contractors follow guidelines to minimize impact their impact on the environment and wildlife following local, state, and federal regulations from the Oregon Department of Fish and Wildlife (ODF&W), Oregon Department of Environmental Quality (DEQ), the Oregon Department of Agriculture (ODOA) and the Environmental Protection Agency (EPA).
In the case of waterways that are under private ownership, the District works with landowners to support their efforts to make drainage improvements. Property owners or residents experiencing drainage issues may contact the District office at 503-281-5675.
