MCWD Dredging Project Underway

The Minnehaha Creek Watershed District (MCWD) is beginning dredging work on two stormwater ponds that clean polluted stormwater that runs off city streets in Minneapolis and Edina.

The Southwest Bde Maka Ska Pond in Minneapolis filters runoff before it enters Bde Maka Ska (formerly known as Lake Calhoun) and the Pamela Park Pond Cell 1 in Edina filters runoff before it enters Minnehaha Creek.

Dredging involves excavating the sediment out of the ponds and hauling it away. Any disturbed vegetation will be restored in the spring.

About 2,000 cubic yards of sediment will be removed from Southwest Bde Maka Ska Pond, which was last dredged in 2012. At that time, the dredged sediment that was removed was near contamination, but current tests indicate the sediment is not contaminated this time around.

About 1,900 cubic yards of sediment will be removed from the Pamela Park Pond Cell 1 and will be the first dredging of this pond. The project is being conducted in partnership with the City of Edina.

Dredging is done during the cold weather months when the ground is frozen. The ponds will be “dewatered,” meaning the water will be pumped out of them and stored in an adjacent pond. The stormwater ponds will then be excavated using heavy machinery. The sediment from the ponds will be hauled offsite.

The work is expected to last through February.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
