North Parnell Site 2 "Gasper Site"- Project 154

General

Construction of the “Gasper Site” began in the spring of 2003 and was substantially completed by the summer of 2003 and functional for operation in the spring of 2004. The project is funded by the Minnesota Board of Water & Soil Resources (BWSR), Red River Management Board (RRWMD), and the District.

Project Location

The Sections 3&4, Parnell Township, Polk County, approximately 12 miles northeast of Crookston.

Design Considerations

The project stores runoff and reduces flooding on downstream agricultural lands and urban areas by retaining up to 324 acre-feet of floodwater. The storage of water in the reservoir also reduces peak discharges on the downstream ditches; Polk County Ditch 126 and the Grand Marais.

Project Components

The project is directly upstream and adjacent to the Parnell Impoundment. The project design consists of approximately 1.0 miles of earthen clay embankment, a grass lined emergency spillway, 1 – line of 36” concrete pipe with a gated outlet structure.

Operable components are the gated structure which releases water from the impoundment into an outlet ditch which then goes into RLWD project 133C, from there the water flows into Polk County Ditch 126. This water then flows west to the Grand Marais Coulee eventually to the Red River of the North.
