Drainage update 6/24/2019

 

Upcoming Drainage Hearings or Meetings:

  • No upcoming major hearings or meetings.                                                                                               

Project Updates:

   

  • CD48 (Cambria Twp.)  We have great news to announce…all new tile for this improvement project have been installed as of last week.  There still remains some check-list items that do include televising the new system.  Those items will be addressed later in the fall after harvest is complete.
  • JD09 (Le Ray Twp.)  Nothing to report for this week. 
  • JD34 (Le Ray Twp.)  Nothing to report new for this week. 
  • JD51 Waseca (Danville Twp.)  Hydro-seeding is all finished up and new tile outlets to the open ditch should also be complete.  Some additional seeding where buffer areas have been disturbed is still to come.  This seeding will be done with a drill instead of hydro-seeding.  Picture below of area of hydro-seeding.jd51 seeding
                                                                                                                                                                                                                                                                          

Drainage Minutes:

I don’t have any overly interesting stories to share this week.  The last week was fairly quiet as far as drainage issues.  I know that some areas of the county did get some big rains and bad weather, but overall most of the county fared well out of isolated heavy storms of last week.

We are still trying to make repairs wherever we can still get in fields.  We started out the year with a pile of repairs from 2018, plus the huge flood of repairs that came in from this spring, 2019.  Our contractors are still doing what they can to get repairs completed.  I do appreciate all our landowners who have been very patient and understanding with us and our contractors during this incredibly busy year.  Please continue to be as patient as we continue to work our way through the list of repairs.

Some upcoming projects this year should include a possible improvement project, if not two, some major repairs to branches and laterals on multiple systems, major ditch cleaning repairs and hopefully our phosphorus filters along CD56 near Lake Crystal.

We are seeing a substantial increase in requests to repair old deteriorating county tile lines all over the county.  Many landowners are feeling the lingering effects of aging tile, which don't always require a complete improvement.  Many times, a repair of newer updated HDPE tile can fix a lot of issues that concrete tile presents.  If the tile is simply too shallow no matter what we do, then an improvement may be warranted.

We have a clean water project underway in Pleasant Mound Township along JD85.  I spoke of this project earlier this year, involving ten new Alternative Side Intakes (ASI), as we call them.  Our contractor started work on these today and should hopefully have them done in a week or two, if mother nature cooperates.  This is just one of three projects I worked with our local SWCD staff to secure grant funding for.  The other two projects should be done later this year, around Fall.  The two other projects are part of two larger open ditch and cleaning projects we have scheduled for later this year.

We have a growing issue with some of our open ditches.  The issue is depth and reach.  As some of our open ditches continue to get taller and wider from clean outs, the challenge is the next time trying to clean or repair them.  We have a few ditches that a 60-foot-long excavator boom won’t even come close to reaching the bottom.  What we are doing on a few ditches now is building a cleaning shelf area.  The excavator can come in anytime of year to make repairs or clean from the designated shelf area that will be positioned safely in reach of any 60-foot-long excavator reach.  The spoils will have to be spread elsewhere or trucked out so as not to create the same problem for future use again.

Recent Drainage Inspections – week of June 17 – June 21:

  • CD35 (Mapleton Twp.)  Almost constant on-going issues with the sloughs and unstable soils along this open ditch.  The 3-4 inches of rain from recent storms left another mess, within weeks of just cleaning portions of this ditch out and hydro-seeding.
  • CD28 (Lincoln Twp.)  Equipment and supplies should start stock piling this week for our repair petition project.  After speaking with the contractor last week, we are aiming for a July 1 start date.  
  • JD51 Was. (Danville Twp.)  Final touches to our major cleaning of this open ditch system.
  • JD48 Bro. (Butternut Valley Twp.)  Inspected on reported issues of ditch bank erosion.  Picture below of ditch bank erosion issue.     jd48 bro
       

Special note that the blog will be moving to a Tuesday posting in the near future.  So, same great blog just being posted one day later on Tuesdays. 

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.
