Four-Legged Lake Flood Damage Reduction (FDR) Project

Project Description:

A region-wide goal has been established to reduce peak flows along the Red River of the North (Red River) by 20 percent during a flooding event similar to the 1997 flood. In order to reach this goal, each tributary of the Red River has been provided with both peak flow and volume reduction goals as set forth in the Red River Basin Commission’s (RRBC) Long Term Flood Solutions (LTFS) Basin Wide Flood Flow Reduction Strategy Report.

Several large-scale modeling efforts have been conducted throughout the Red River Basin to assist in determining the amount of effort required to meet the flow and volume reduction goals in each tributary basin of the Red River. HEC-HMS models for the RLWD major subwatersheds have been developed as part of the Red River of the North Basin-Wide Modeling project. These models were also used in 2013 for the RLWD Expanded Distributed Detention Strategy project to determine locations for potential detention sites within the RLWD, in an effort to assess which areas of the watershed have the highest ability to reduce peak flows and volume at Crookston. This project revealed that the Four Legged Lake subwatershed is a strategic area to add detention and reduce peak flows at Crookston. There are also opportunities to modify the Four Legged Lake control structures in a way to reduce flood risk to local landowners, enhance environmental conditions within the subwatershed and add recreational benefits.

The current project will be completed for the RLWD in accordance with NRCS procedures. The end result of the project will be documentation of environmental resources within the watershed, evaluation of alternatives, documentation of environmental impacts and design performance of evaluated alternatives, determination of environmental status (Categorical Exclusion, EA, Enviromental Impact Statement ), and selection of a preferred alternative that meets project goals (assuming the project does not warrant further study through completion of an EIS).

The goals of the current effort include:

    • Flood Damage Reduction
    • Water Quality Enhancement
    • Improve Habitat for Fish and Wildlife
