Clean the tree debris in the creekFriends of Koshkonong Creek has initiated this step since 2017 with help from Capitol City Water Trails. Tree removal work has started in various sections of the creek upstream from Hwy 73 to Baxter Road. The creek bottom has been cleaned and dredged up to 2 feet to remove sediment build-up. This process will continue until the large Cottonwoods and Box Elder trees are eliminated or controlled.
Dredge the creek from Hwy 73 to Baxter RdClearing tree debris from the creek has proven to somewhat alleviate the flooding time period to more normal time frames, but the minimum water level has not returned to the levels that local farmers had historically seen 40 years ago. The higher water level causes additional erosion, which eventually causes more tree falls into the creek, exacerbating the problems further. The minimum water level in the creek will not return to historical levels without active silt removal, so we advocate dredging the creek this year and next year. We recommend the use of mini dredges that are on floats and only suck the muck, which will then be returned to the fields.
Study and inventory the creekObserve the state of the creek as it exists now, and plan for the next 50 years. This is the heart of the study to be performed by the UniverCity Alliance.
Modify the creek to handle flowsMake adjustments to the creek so that it can handle current and expected long-term flows. Conclusions and recommendations made by the University Alliance study will be discussed by stakeholders, funding will be determined, and the timing of the construction work to be performed will be set.
Plan for ongoing maintenanceOnce the creek is cleaned and modified, it is imperative that the creek now become maintained on a regular basis. The neglect it suffered since it had been originally dredged should not be repeated.
