Drainage update 9/29/2020
Upcoming Drainage Hearings or Meetings:
Blue Earth County have been hosting board meetings and some drainage hearings virtually. Blue Earth County staff have been using a combination of live-streaming video and conference call-in options. Notices sent out for drainage hearings will include all necessary information for our constituents to attend these hearings virtually via internet or through the call-in option.
Pretty quiet lately in the world of drainage, as far as news media. Usually we have had a few seminars or drainage related events to talk about at this time of the year, however, COVID-19 has changed all those plans, as much as it has for all of you. In the absence of drainage seminars, we have been keeping busy making as many repairs as we can across the county.
We have been keeping multiple contractors busy with ditch cleanings, slough repairs, installing water quality in-takes (ASI’s), installing new crossing structures and tree and brush maintenance. We currently have six different contractors completing work on multiple drainage systems across the county.
Speaking of water quality in-takes, we have started installing over 30 new water quality in-takes along portions of open ditch on ditch systems CD26 and JTD83, both located in McPherson Township. Think of how many thousands of tons of sediment those 30 new in-takes will prevent from entering those two open ditch systems. Less sediment equals better water quality and less future maintenance costs for the drainage system. We are trying to rebuild some of our larger areas of sloughing by replacing and packing these areas with clay and re-seeding them. Slough areas are very hard to find a silver bullet solution, as there are usually multiple factors contributing to why these areas are sloughing.
Fun fact about Blue Earth County Drainage Authorities commitment to water quality, in the last year and a half, Blue Earth County Drainage has been awarded over $150,000 in grant funding to support water quality efforts and practices. Some of those practices include, Alternative Side Intakes (ASI), a phosphorus filter installed and concrete control weir structures, to name just a few. Our latest concrete control structure to be installed was along a portion of CD05. This was part of a grant funded program. This will control peak flows to portions of CD05 and help keep the wetland area more like an actual wetland, holding water longer. The photo below shows one of our grant funded weir control structures along CD05.
Now that we are officially into our fall season, repairs and contractors are in frantic mode, trying to get as much done before things freeze up. Looking towards next year, we are expecting multiple new projects as well as many repairs.

We have multiple contractors making repairs across the county currently. Please report repair issues to our drainage staff as soon as you notice them, as this will expedite the time in getting those repairs made.
We require that all repairs to a county drainage system (tile or open ditch) be authorized by one us in the drainage office, either Craig or myself, before any repairs are made. We also do not allow any permanent or seasonal items to be placed in our open ditches or buffer areas. These types of items would include rocks, fence posts, trailers or other agricultural equipment, just to mention a few items. If you have questions or concerns with open ditches or buffers, please call.
