Logjams are tree and other debris that have fallen in the river resulting in blocked navigation on the river.

Assisting Navigation and Wildlife

During the summers of 2019 and 2020, the Friends of the Baraboo River received significant funding from Sauk County to cut a 10 foot pathway among targeted logjams on the Baraboo River. This funding was in response to the 2018 flood that resulted in major logjams on the Baraboo River. The Friends hired an insured contractor to manage the work.

  • All DNR rules were observed

  • Access to the logjam was gained by boat

  • Cut tree debris was returned to the landowner, if requested

  • Special permission was gained from landowners if heavy equipment required land access

  • A narrow 8’ to 10’ pathway was cut through the logjam, with the remaining debris left in place to encourage fish and wildlife habitat

FAQs

  • Restoration of Natural Flow: Logjams can alter the natural flow of the river, leading to changes in the river’s flow and ecosystem. Removing them helps restore the natural flow, which is crucial for maintaining the health of the riverine ecosystem.

    • Improved Water Quality: Logjams can trap organic matter and pollutants, which may lead to decreased water quality. Removing these obstructions can improve water quality by allowing better aeration and flow.

    • Habitat Restoration: The natural flow of the river supports diverse aquatic habitats. Selective pathway cutting through logjams can help maintain habitats for fish and other wildlife, promoting biodiversity.

  • Enhanced Navigation: Logjams can obstruct navigation for boats, canoes, and kayaks. Their removal facilitates safer and easier navigation, promoting recreational activities such as boating, fishing, and paddling.

    • Improved Recreational Access: The removal of logjams can open up sections of the river that were previously inaccessible, enhancing recreational opportunities for the local community and visitors.

  • Reduction of Hazards: Logjams can pose significant safety hazards for recreational for paddlers and allows for improved access for emergency boats.

    • Infrastructure Protection: Logjams can cause damage to bridges, culverts, and other infrastructure by increasing water pressure and leading to erosion. Removing them helps protect these structures from potential damage.

DNR Guidelines for Removal of Tree Debris on a River

Logjam removal can be a complicated process. DNR rules must be followed.
