Regulatory Public Notices

MVP-2026-00584 Wubben Dredge, Letter of Permission
The applicant is proposing to dredge approximately 775 cubic yards of sediment from 0.2 acres within Lake Arbutus for the purpose of restoring navigable water depths to provide safe access and mooring for mid-sized recreational watercraft. Dredging would be performed using a floating mechanical excavator and 3 cubic yard material barges. Excavation would remove accumulated sediment to a 2H:1V slope to a depth of 4 feet. Scuppers would be utilized on the material barge to allow the sand to decant and not cause water saturation issues at the placement site and haul road. Excess water would be allowed to drain from barges prior to transport to minimize haul road degradation and off-site tracking. Material would be off-loaded via excavator, trucked via the existing access road to the upland placement site on the applicant’s property. Project completion shall be achieved when the excavation limits and design grades have been attained, dredged material has been placed within the designated upland placement area, disturbed upland areas have been graded to promote positive drainage, and all temporary erosion-control measures are functioning as intended.
Date of Expiration: 08/07/2026
Special Public Notice, Letter of Permission
The applicant proposes to hydraulically dredge approximately 1,700 cubic yards of accumulated sediments for improved access to Lake Onalaska (Mississippi River). The proposed dredging area has silted-in over time, which has restricted water access to the parcel owned by the applicant. The project area would be dredged to an approximately 4’ water depth at normal pool level. All dredged material would be pumped via dredge-hose to an adjacent upland parcel for dewatering and permanent disposal.

Tamarack Creek ILF Site
The Wisconsin Wetland Conservation Trust (WWCT) proposes to construct the Tamarack Creek In-Lieu Fee (ILF) site in the Town of Trempealeau. The WWCT intends to restore approximately 38.28 acres of wet meadow wetlands within the ILF site. Wetland functions would be restored by disabling the existing tile, filling ditches, and returning native wetland and upland vegetation to the property. The site was historically drained for agricultural uses and is currently being hayed. The sponsor is proposing this in-lieu fee site concurrent with an adjacent bank site proposal, which are being designed to restore a contiguous wetland complex adjacent to Tamarack Creek on both properties.
Date of Expiration: 08/21/2026
Tamarack Creek Wetland Bank
The Tamarack Creek Mitigation Bank Site is a proposed wetland compensatory mitigation bank in the Town of Trempealeau, Trempealeau County, Wisconsin. The project site is approximately 48.26 acres located within the Upper Mississippi-Black-Root Bank Service Area (BSA). The site is currently used for hay production on agriculturally drained wetland and is bisected by a network of drainage ditches and subsurface tile. The site contains approximately 46.03 acres of field-delineated wetland, predominantly degraded wet meadow dominated by invasive reed canary grass, with a small wooded swamp community along Tamarack Creek in the western portion of the site. The objective of the project is to restore wetland habitat and improve wetland functions by filling approximately 4,616 linear feet of interior drainage ditches, disabling subsurface drain tile, controlling invasive species, and re-establishing native wet meadow and wooded swamp plant communities. The project is anticipated to generate approximately 32.50 wetland credits through a combination of re-establishment, rehabilitation, and enhancement across multiple credit areas.
