The City of Columbia Water Department has been "stepping" up their work. Since mid-January, the Water Department has had a crew of two or three operators working on construction of over 18 "steps" and "pools" to replace an incised channel.
|Looking upstream, incised and eroding channel is approximately three feet deep.|
|Work begins with clearing underbrush to access the downstream part of the channel.|
|Looking downstream, the Forestry Division of the Parks & Recreation Department clears the underbrush and Water Department prepares access to the site.|
|Looking upstream, access is complete and step pool construction can begin.|
|Looking downstream, various sizes of rock are used to install the step pools.|
|Looking downstream, pools are stepping down to the right.|
Many steps and pools are yet to be constructed over the next month or so. Meanwhile, shredded mulch is placed to prevent surface erosion. Planting will take place this spring.
US Environmental Protection Agency Region 7, through the Missouri Department of Natural Resources, has provided partial funding for this project under Section 319 of the Clean Water Act. (G11-NPS-12).
