Over the next two years, the eight-mile stretch of Nine Mile Creek running through Hopkins will be transformed from a muddy drainage ditch into a pretty, meandering stream.
Starting this month and during winters when the water is low, workers for the Nine Mile Creek Watershed District will relieve the creek of overgrown brush, soften the slope of its banks, line its bed with smooth river stones, and reroute it into a curving channel through Hopkins' Valley Park.
"Right now it's a glorified drainage ditch," said Hopkins city engineer John Bradford. "It's going to be a more attractive amenity and increase the natural habitat of the creek for wildlife."
The ambitious $4.5 million Hopkins project is aimed at stopping erosion and making the water more hospitable to fish.
The project will "re-meander" the creek from a straight channel dug in the 1960s and 1970s and return it to its original location, said Bob Obermeyer of Barr Engineering, the watershed district's engineer. He said the district has no record of why it was moved and straightened.
Eric Evenson, director of Minnehaha Creek Watershed District, said many creeks were straightened years ago to accommodate development or farming or to increase drainage.
Minnehaha Creek was re-meandered near Methodist Hospital in St. Louis Park in 2008. In 2010, the Department of Natural Resources and Trout Unlimited will put curves back into the Vermillion River.
The restored segment of Nine Mile Creek will have the curving channel and gently sloping sides of a natural stream instead of steep, straight banks with sloughing dirt and exposed tree roots, said watershed district director Kevin Bigalke said. "From the public's perspective it will be a significant enhancement," he said.
