Drainage update 8/20/2020


Upcoming Drainage Hearings or Meetings:

Blue Earth County has recently started hosting board meetings and some drainage hearings virtually.  Blue Earth County staff has 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.

  • JD15 hearing coming up next week.  Those affected landowners should have received notice and hearing details via U.S. Mail.                                                                                                  

Drainage Minutes:

Just a quick drainage update this week.  Things are still staying busy and only to get busier in the coming couple of months.  We are still making repairs to various drainage systems across the county.  We are working in areas that we can, as crops are still in, minus a few areas of canning crops.  We currently have a major repair going on CD05 in Danville Township.  We are nearing some of the final stages of this cleaning.

As of August 17, 2020, crews had our new large box culvert set and flowing, as well as the footings for our new wetland control weir.  The new control weir will replace an old failing weir in one of our areas of wetlands along a portion of open ditch.  The idea behind installing a new weir is, it will control flows in and out of the current wetland area.  It will store more water, making for a more critter friendly ecosystem.  The benefits of more water storage and better controlled out flows is a benefit for all CD05 benefitted landowners.  The cost for this control weir is funding provide by grants from the State of Minnesota.

CD01 located in McPherson Township got a new ASI last week.  ASI? Alternative Side Intake, one of many water quality structures Blue Earth County drainage uses to improve performance and water quality of our drainage systems.  Installation turned out great, just need some grasses to take root and things will be looking perfect, see photos below.cd01 asi

Repairs for CD26 and JTD83 (joint with Waseca County), these two repairs will be starting in the next few weeks.  Both repairs include open ditch cleaning, some new crossings and buffer area seeding.  Multiple contractors will be working side-by-side getting these two repair cleanings completed this year.  JTD 83 will include a section of new tile line that needs repair.  Approximately 1,000 linear feet of new tile will be laid near the open ditch inlet, or the top side of the open ditch system.

I am still confident that we will have one new improvement project bid this side of the calendar year, with two, if not three, more improvements following up early next year.  We do still have a couple improvement projects to try and close out this year also. 

Well, that’s all for this week.  Nothing to exciting to read this week, but things are still busy and we are still working as hard as we can to keep all repairs and projects moving forward.

Project Updates:  

  • JD34 (LeRay Twp.)  No change from last week.  Hoping to close this project out yet this year.
  • CD05 (Medo and Danville Twps.)  Crews are working hard with leveling spoils and getting new buffer seeding done.  Crews also set a new box culvert and our new concrete weir structure has been started.  Each section of the new box culvert weighed approximately 22,000 pounds, so no small feat by any standards.cd05 culvert

  • JD09 North (LeRay Twp.)  No change from last week.
  • CD48 (Cambria Twp.)  Fall checklist items remain.

Recent Drainage Inspections:

  • CD56 (Garden City Twp.)  Portions of new tile line have been installed.  Areas of repair remain, mostly being small areas of repair. 
  • JD17 (Garden City Twp.Our new 6-inch tile is still set to be installed, hopefully later this week or next.  Having a new dual wall plastic line and two new in-takes in the road right of way area should drastically help drainage issues in this localized area.
  • JD48 Brown (Butternut Twp.)  The use of last weeks drone has proven to be almost invaluable.  It improves the safety of our crews and give drainage staff a much more in-depth view of issues going on along portions of the open ditch.
  • CD05 (Danville Twp) Crews have made great gains in the last week, despite the heavy rains from last week.  Crews have been cleaning open ditch, spreading spoils, seeding buffers, installing new crossings and started installed a new control weir.
  • JD116 Martin and Faribault (Pleasant Mound Twp.)  The major areas of tree clearing are just about done.  Ditch cleaning and outlet repairs will be starting within the next month.  Our two neighboring public drainage systems, JD82 and JD85, will also be getting cleaned yet this year. 
  • CD69 (Mankato Twp.)  Monitoring functionality and water levels in this public drainage system that meets urban in-town living.  Things looked good and water was flowing fine as of last Friday, August 14.

Do you have questions or topics about drainage that you would like to here more about? If you would like me to incorporate those concerns or topics in one of my future blogs, please feel free to email me at the listed email address below. 

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.
