PurposeWatershed plan update 2011. The Marengo River Watershed is located in central Ashland and south central Bayfield counties in the Lake Superior Basin of northern Wisconsin. It is contained within the Bad Montreal Watershed and covers an area spanning 218 square miles or approximately 139,313 acres. The western third of the Marengo watershed is located within Bayfield County and the eastern two thirds within Ashland County. Parts of ten townships, `including: Ashland, Gordon, Grand View, Kelly, Lincoln, Marengo, Morse, Namakagon, Sanborn, and White River are located within the watershed. The northeast corner of the watershed, which includes the mouth of the Marengo River, is located within the reservation of the Bad River Band of the Lake Superior Tribe of Chippewa Indians. There are no incorporated cities or villages within the watershed. Unincorporated villages include: Marengo, Highbridge, Sanborn, and North York. Due to erosion and sedimentation caused by land use, topography, and geologic conditions within the watershed, the Marengo River Watershed has become an important focus area for highlighting “slow the flow,” the key management strategy to reducing sedimentation in Wisconsin’s Lake Superior Basin. A community watershed planning effort, called the Marengo River Watershed Partnership and led by the Bad River Watershed Association (BRWA), began in 2009. The planning effort has identified key issues and concerns and is completing an EPA nine-element Watershed Action Plan to address them. Issues and recommendations identified in this report will contribute to the Watershed Action Plan and the current working draft of the plan is largely excerpted in this report.
Study DesignWatershed specified for planning and assessment purposes. Assessment of water quality condition in this respective county will use protocols described in WisCALM of the year of assessment. Minimum assessment work includes biological data (macroinvertebrates, fish indices), chemistry and habitat data. Additional work includes identification of priorities and goals, creating recommendations for actions, and updating narratives for watersheds and waterbodies. Assessments are to be double checked by at least one additional biologist.
