Construction continues at the Red Rock Dam hydroelectric power plant site. Much of the current work is in preparation for construction of the powerhouse, which is expected to begin this summer.
Vern Cochran with Missouri River Energy Services says on the downstream side, the construction of the cofferdam, which is located between the Des Moines River and the power plant site, is underway. He says the cofferdam will help create a dry work environment during the construction of the power plant. This week, construction crews have started to install tieback anchors that will anchor the retaining wall into the bedrock.
