Lake Red Rock


Lake Red Rock is Iowa's Largest Lake with over 15,000 acres of water and 35,000 acres of land for your enjoyment.  Located on the Des Moines River just 45 miles southeast and downriver from Des Moines, the reservoir collects runoff and and drainage from over 12,320 square miles of Iowa and southern Minnesota land.  This protects communities and agriculture lands downstream from the Red Rock Dam.  The maximum flood control pool is 780 feet above sea level, over 33 miles long, and covers 65,500 acres.  Other lake area benefits include numerous recreational opportunities and natural resources on the water and surrounding public lands.

T15 closure still planned for Oct. 30
SIOUX FALLS, S.D. – Plans remain on track to close a section of Highway T15 that crosses over the Red Rock Dam beginning Oct. 30. That road closure is necessary to facilitate some of the construction of the Red Rock Hydroelectric Project, which is being built at the Dam. Missouri River Energy Services (MRES), which is building the project, projects that the section of road will be closed to all traffic for about 10 to 12 weeks. During that time, large construction equipment will be positioned on T-15 making the road inaccessible to traffic. MRES will keep the public up to date about any changes in the road-closure date or schedule.

T15 To Be Closed to All Traffic Beginning October 30
SIOUX FALLS, S.D. – A section of Highway T15 that crosses over the Red Rock Dam is projected to be closed to all traffic for about 10 to 12 weeks beginning October 30. This date could change due to future weather and lake conditions. The road closure is necessary while large construction equipment drills and constructs a large subsurface wall that will be tied into the existing dam structure. In order to complete this work the equipment will be positioned on T-15 making the road inaccessible to traffic until this phase of construction is completed. Missouri River Energy Services (MRES), which is building the project, will keep the public up to date about any changes in the road-closure date. A detour route will be established and signage will be in place to direct traffic in the area. The hydroelectric plant, when completed in 2018, will be capable of meeting the electricity needs of about 18,000 homes. “We know that this causes an inconvenience for daily traffic, but MRES and Ames Construction are doing everything we can to minimize disruptions to traffic during construction of this new hydroelectric facility,” said MRES Director of Member and Public Relations Bill Radio. MRES encourages people who are concerned about the road closure or interested in any aspects of the Red Rock Hydroelectric Project to visit the project’s website: www.redrockhydroproject.com. ### For more information, contact MRES Member and Public Relations Director Bill Radio, phone: 605-338-4042; e-mail: bill.radio@mrenergy.com.

3M Volunteers Expand Playscape at Lake Red Rock
On Saturday, September 27, staff from 3M in Knoxville and their families donated many hours of “sweat equity” to add new features to Lake Red Rock’s “Playscape,” a natural play area located along the north side of the lake. The Playscape is designed to spark children’s creativity in using natural features in their play. The outdoor experiences will hopefully build their love and appreciation of nature, increase their feeling of ownership of their environment, and become future stewards in protecting our natural resources. Last November, 3M awarded the Red Rock Lake Association a $30,000 EcoGrant to help expand the Playscape. The funds have been utilized to pay for building materials, a stipend for a Playscape Intern to offer programming throughout the summer months, environmental education materials, and other supplies. During this process, 3M also volunteered to help with the building effort.
