Erosion Control

We are just back in from the Minnesota Erosion Control Association Conference.  It was held at the DECC in Duluth the last 3 days.  Great workshops and a whole team of people learning and sharing about ways to help keep water clean by helping keep soil in its place.
We also learned about phosphorus coming from leaves that fall off trees in the fall, stream geomorphology and tools that people use to restore streams.   The importance of compost, the importance of planning for projects - including having plans for well beyond the time activity occurs at a site (mine reclamation), and also ways cities can fulfill permit requirements through training staff and local businesses that might be a source of polluting activities (such as restaurants with grease).  The city of Duluth gave a presentation on recovering after the 2012 flood - pictures showed how intense and changing the high water flow had on numerous streams.  Woody debris - even whole trees - were swept in the streams and blocked culverts.  Stream banks had considerable erosion creating the reddish plume in Lake Superior that lasted for weeks.  Repairs have been made to roads that suffered from water damage and plantings have been put in some of the main disrupted stream banks.  Restoration continues.

An exhibitor area had products ranging from native plant landscaping to products to use to make permeable pavement areas to engineering places that have products to insert in storm drains.  Above ground and below products and learning better management and education outreach reduce pollutants and sediment from entering our local waterways.

This was the first year MECA held their conference in Duluth. 
Thanks for bring the conference up north to advance the area's knowledge and techniques with controlling erosion.
