Lake Ashtabula and Baldhill Dam, Water Control Manual Update
The Water Control Manual, or WCM, provides operational parameters defining how and when water is stored and released. These include a schedule of releases, conservation pool levels to be maintained during non-flood or drought conditions, and downstream water level constraints. Lake Ashtabula is authorized for flood control and water supply. It is also authorized for the additional purposes of pollution abatement and recreation and fish and wildlife management. The US Army Corps of Engineers has reviewed the existing WCM and is proposing to revise operating parameters to better serve the project purposes. This review resulted in the creation of a draft Decision Document with an Integrated Environmental Assessment. The selected plan does not involve any modifications to the dam structures, but rather is evaluating how to best manage water using the existing project infrastructure.

Regulatory Public Notices

Lanners Wetland Bank Development
The proposed mitigation bank project is in BSA 7, which has approximately 23 counties located wholly or partially within its boundaries. The sponsor states that there are currently 36 approved mitigation banks within BSA 7. Twenty-six have federal and state credits available and ten (four are agricultural banks) have State-only credits available. Sixteen of the 26 banks with federal and state credits have less than two credits available. Population centers such as St. Cloud, Hutchinson, Monticello, Rogers, Albertville-St. Michael, and a portion of the Twin Cities metro area are included in BSA 7. These areas are rapidly developing, and future wetland impacts are anticipated which could require compensatory mitigation indicating a future need for bank credits.
Date of Expiration: 06/14/2025
Silver Lake Dredging and Dam Modification
The purpose of the project is to modify the Silver Lake Dam and to dredge the Silver Lake flow channel to lessen a public safety drowning hazard, to remove a barrier to aquatic organism passage, to maintain the lake’s capacity for flood passage, and to improve recreational navigation of the lake.

Special Public Notice for Cultivated Fields Methodology
The U.S. Army Corps of Engineers St. Paul District Regulatory Division (Corps) and Wisconsin Department of Natural Resources (Wisconsin DNR) are announcing the opportunity to use a standardized method for determining credit potential associated with proposed wetland hydrology restorations in fields that are subject to annual cultivation. The Corps and Minnesota Board of Water and Soil Resources (BWSR) developed this methodology for use in Minnesota in 2019, and since then, implementation of this methodology has helped to streamline credit determinations. In Wisconsin, applicants proposing permittee responsible mitigation or sponsors proposing bank or in-lieu fee wetland restoration projects may use this methodology in association with seeking project approval under the 2008 Federal Mitigation Rule (33 CFR Part 332), and ch. NR 350, Wis. Adm. Code.
Date of Expiration: 06/07/2025
Wisconsin Environmental Restorations Mitigation Proposal
This project involves the modification of an existing, approved wetland mitigation bank site. Mitigation banks are approved by the U.S. Army Corps of Engineers for the purpose of providing compensatory mitigation credits which sponsors sell to permittees seeking Department of the Army authorization for impacts to aquatic resources. The Corps originally approved the Bluff Creek Wetland Mitigation Bank on October 9, 2020. The Sponsor completed site construction and seeding in 2020 and received their initial credit release for construction in January 2021. In 2022 the Sponsor and Interagency Review Team (IRT) identified issues with the site performance, specifically the failure of an outlet structure and deficient of wetland hydrology or vegetation. As a condition of the continued sale of previously released credits and future release of additional credits, the Corps required the Sponsor to develop a corrective action plan to address these issues and bring the site into compliance with the objectives of their mitigation plan.
