LAKE REDWOOD RECLAMATION PROJECT

  •  The main objective of this final BMP project is to remove up to 650,000 cubic yards of sediment increasing the current average depth of  2.8 feet to its original maximum depth of 20 feet.
  • RCRCA a watershed based JPO and partners have implemented over $9,000,000 of BMPs, water quality monitoring and educational programming since 1994 reducing sedimentation by over 27,276 tons per year.
  • As with any river based reservoir, sedimentation will continue at the reduced rate of 0.13 feet per year (down from 1.5 feet), the return on investment will be realized over 3.4 years by trapping 16,500 tons annually from reaching the Minnesota River, the Mississippi River and eventually Lake Pepin. Ironically this trapping efficiency is an equivalent to spending $2,000,000,000 annually over the next 70 years in traditional conservation BMP implementation to equal the reclaimed storage.
  • Project outcomes include: treating TMDL impariments in the Minnesota River by trapping up to 16,500 tons of sediment and 11 tons of phosphorus annually, increased hydroelectric power generation for the City of Redwood Falls reducing the need of 14 train cars or 1,342 tons of coal as well as enhancing regional recreational opportunities.
  • Lake Redwood is one of two remaining lakes located in Redwood County and both are man made reservoirs.

2023 Lake Redwood Reclamation Activities

► Restoration of unvegetated areas (laydown Area, Confined Disposal Facility (CDF), and other areas)

► Mathiowetz Construction managed the sand pile and internal CDF drainage.

► CDF was seeded aerially by Mulder Air in September.

► CDF ownership will be transferred to the City of Redwood Falls in 2024 for continued management. 

► a removable handicap-accessible fishing pier will be installed in 2024 through a dnr cooperative agreement with the city of redwood falls.

► signage will be added to the lake and CDF acknowledging the source of the state funding and map of the lake depths.
