Environmental Impact Statement; Coon Creek Watershed
AGENCY:
Natural Resources Conservation Service, USDA.
ACTION:
Notice of availability; record of decision.
SUMMARY:
This notice of availability presents the Record of Decision (ROD) on a Watershed Project Plan-Programmatic Environmental Impact Statement (Plan-PEIS) for the Coon Creek Watershed prepared in partnership with La Crosse, Monroe, and Vernon Counties, Wisconsin (Sponsors). This notice announces the plan to proceed with the implementation of Alternative 2-Proposed Action-Decommission Dams, identified in the Plan-PEIS. Alternative 2 proposes to decommission all 14 dams by excavating a notch to pass the 100-year flood without impounding water. This action will avoid environmental impacts to the extent possible and mitigate impacts that are unavoidable.
ADDRESSES:
You may request a copy of the ROD from: Steve Becker, NRCS State Conservation Engineer, 8030 Excelsior Drive, Suite 200, Madison, WI 53717.

SUPPLEMENTARY INFORMATION:
Decision
Natural Resources Conservation Service (NRCS) has prepared a ROD following completion of the Plan-PEIS. The Plan-PEIS provides a retrospective analysis of the existing flood control project and then evaluates alternatives for the final disposition of 14 flood control dams. The purpose of the Plan-PEIS is to ensure agencies consider the environmental impacts of their action in decision making. NRCS involvement is through Public Law 83-566, Watershed Protection and Flood Prevention Act, as amended. The ROD is available for viewing at the following link: https://www.wfkandccwatersheds.com/2023.
NRCS has decided to assist the Sponsors with implementing Alternative 2 which proposes to decommission all 14 dams in the watershed.
Background
The Coon Creek Watershed has an area of 90,601 acres (141.6 square miles) to the confluence with the Mississippi River. The focused planning area for the Plan-PEIS is 68,762 acres (107.4 square miles). The Plan-PEIS is follows an original Watershed Work Plan developed in 1958 to reduce flood damages in the Coon Creek valley under the Watershed Protection and Flood Prevention Act of 1954, as amended.
The major problems in the watershed in 1958 were floodwater damages to: crops and pasture, fences, farmsteads, machinery, buildings, livestock, county and township roads and bridges, and urban areas of Coon Valley and Chaseburg. Project measures implemented under the original Watershed Work Plan included 14 flood control dams installed between 1961 and 1964 with a total capacity of 1,160 acre-feet to regulate flood flows from 21 square miles, or 27 percent of the watershed above the village of Coon Valley. Project measures also included a multitude of land treatment practices to reduce erosion and sedimentation behind the dams. The dams have now completed their Federal interest or original economic evaluation period of 50 years.
On the night of August 27, 2018, seven watershed dams over-topped and three dams failed including the Luckasson Dam (CC 21); Blihovde Dam (CC23); Korn Dam (CC 29). Rainfall amounts up to 11 inches were reported on the night of August 27 and early morning of August 28. Additional rainfall amounts up to 7 inches were reported in the afternoon of August 28 after the dam failures.
The dams failed (breached) along the interface between the earthfill and highly jointed sandstone abutments. Each breach extended full depth to the valley floor. No one was injured or killed. Large debris fields were observed downstream of the dams for about 2 miles. Barns and outbuildings were destroyed. An unoccupied house was moved off its foundation. Agricultural lands and road crossings were damaged. Engineering investigations concluded that flow through the jointed sandstone during high pool stage caused internal erosion and piping of the earthfill dam and contributed to the failures. The Sponsors and NRCS are concerned that a similar vulnerability exists in the remaining 11 dams.
Environmental Review
[top] The ROD summarizes the findings of the Plan-PEIS and provides the basis for a decision to decommission 14 flood control dams in the Coon Creek watershed. The watershed project plan and the environmental document were combined in the single Plan-PEIS document. NRCS is the lead Federal agency responsible for the content and quality of the Plan-EIS for the purposes
The ROD is issued for the NEPA process (42 U.S.C. 4321-4347) which follows the NRCS NEPA regulations in 7 CFR part 650, subpart A, and 7 CFR part 622. The NRCS NEPA regulations adopt the Council of Environmental Quality (CEQ) NEPA regulations (40 CFR parts 1500-1508) in total.
Alternatives
Considered alternatives included: no action, repair, rehabilitation, relocation, replacement, removal, and construction of additional dams. Considered alternatives also included the substitution of large watershed dams with a multitude of smaller farm ponds. Further effort was made to evaluate the effects of various land management strategies to reduce watershed runoff and flood damages were compared for present land use against a full watershed conversion from cropland to grassland.
Two of nine alternatives were provided for detailed study and comparative analysis: No action and Decommission dams. The No Action alternative does not address dam safety. Two failed dams, plus three failures in the adjacent Coon Creek Watershed, present a high probability for future failures. The State Dam Safety Program has issued an administrative order to Monroe County, as the owner, to repair or remove the two failed dams; similarly, they would likely order the repair or removal of the seven remaining dams if they fail in the future. The Decommission Dams alternative proposes to decommission all nine dams to prevent future dam failures and potential loss of life and property damage.
Factors Considered in Making the Decision
Geologic and geotechnical engineering investigations were conducted following the failures of CC 21, CC 23, and CC 29. The investigation report concluded that flow through the fractured sandstone abutments during high pool stages contributed to the failures. A similar vulnerability is believed to exist in the remaining structures.
Failure of the remaining dams could result in loss of life and would likely cause downstream flood, erosion, and sedimentation damages to cropland, farm structures, road crossings, and utilities. Dam failures would also result in erosion and sedimentation of streams resulting in adverse impacts to fish and wildlife habitat.
All programmatic alternatives have submarginal economic performance. They have negative discounted net economic efficiency and very low benefit to cost ratios. However, the preferred alternative of dam decommissioning decreases People at Risk (PAR) from a dam failure and increases length of natural stream connectivity for habitat and recreation. The preferred alternative is justified by the social (PAR and recreation) and environmental (stream restoration) accounting of the PR&G for Federal Investments in Water Resources.
Public Notice
As specified in 7 CFR 650.12(c) and 40 CFR 1505.2, the Draft PEIS public notice was initiated by publication of the Draft PEIS on December 22, 2023, and published in the Federal Register (88 FR 88610), as identified by EIS number 20230180 in the Environmental Protection Agency's (EPA) Central Data Exchange (CDX) system. Concluding the initial public notice, essential comments were addressed and incorporated in the Final PEIS. The Final PEIS was made available for review through EPA's CDX system on May 17, 2024, and published in the Federal Register (89 FR 43401).
Conclusion
The Plan-PEIS for the Coon Creek Watershed uses all practical means, consistent with considerations of national policy, to meet the goals established in NEPA. The Plan-PEIS will serve the overall public interest and meet the needs of the project sponsors. The Plan-PEIS has been prepared, reviewed, and accepted in accordance with the provisions of NEPA as implemented by Departmental regulations for the preparation of a PEIS. After considering a broad range of alternatives, the PEIS has found Alternative 2-Proposed Action-Decommission Dams, to be the environmentally preferable alternative to serve the Sponsor's purpose and need.
NRCS has decided to assist Sponsors with the implementation of Alternative 2 to decommission all 14 dams by excavating a notch to pass the 100-year flood without impounding water while avoiding environmental impacts to the extent possible and mitigating for impacts that are unavoidable.
NRCS has prepared a concise ROD for this action. The ROD was prepared and will be signed by the State Conservationist (STC) following the 30-day administrative action period initiated by the EPA's publication of the notice of availability of the Final PEIS in the Federal Register . The ROD will be distributed to all who provided essential comments on the Draft PEIS and will be available for review upon request.
