Drainage update 7/28/2020

 

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.

  • No upcoming hearings.                                                                                                                                                                                                                                                     

Drainage Minutes:

Not much of anything exciting to report in the world of water and drainage, at least from my normal news sources.  However, those of us that live in Blue Earth County experienced lots of excitement over the weekend, some of us to the tune of 8 inches or more.  Just because there isn’t much going on in the media in terms of drainage, doesn’t mean we can’t make our own news. This past Saturday, July 25, 2020, was a flash flood situation for many areas of Blue Earth County. 

We had reports from ¾ of an inch to over 8.5 inches of rain that feel last Saturday, mostly between midnight and 9 am Sunday.  I can’t say that it’s been a long time since we’ve had a super soaker like this, because it wasn’t terribly long ago that Cambria and Butternut townships received very large amounts of rain overnight also. 

Well ,besides the rain last Saturday night…did anyone get out and enjoy the weekend?  I, along with a few partners in crime, did some river tubing down the Blue Earth and Minnesota Rivers.  I have included a map of our route we took, but we started at Red Jacket Park and ended in Mankato at Riverfront park.  This may have been one of the longest floats I’ve been on in my life.  Looking at the map it doesn’t seem like a long distance, but when the water levels are low and very little flow to the water, things take a while.  It took us around six hours to float that distance.  Maybe next time we will do kayak’s which should drastically speed up the pace.  Despite popping one of the tubes on a tree branch, the adventure was a great success and we all made it back home safely.  Photos from below include our route we floated and a couple views from riding the river.        RIVER ROUTE

Project Updates:  

  • JD34 (LeRay Twp.)  Hoping to close this project out very soon.
  • CD05 (Medo and Danville Twps.)  Things were moving along well until last Saturday’s rains.  The open ditch cleaning will have to wait until the ditch water level drops back down.  Trees and brush removal is still going on.
  • JD09 North (LeRay Twp.)  No changes from last week.
  • CD48 (Cambria Twp.)  No changes from last week.                                                                                                                                                                                                                    

Recent Drainage Inspections:

  • CD56 (Garden City Twp.)  Parts of this repair did get finished up last week, while others did not, before the rains struck us once again.  The photo shown is actual right near one of the repair areas.  The photo shows about 2 feet of water going over the top of a township road.
  • JD17 (Garden City Twp.)  Good news / bad news situation with this one.  Good news is that the two-hundred-foot trench is all fixed up with new pipe and things are running like they should.  Bad news, we found another area with an almost completely plugged 6-inch concrete original line.  We did have a contractor working on opening the old line, versus digging up the township road, but Mother-Nature put the kibosh on our plans over the weekend.  It will be awhile before things dry up enough before repairs resume and tile lines are cleaned.  Photo below showing where we are trying to clean out an old line.flooding 2
  • JD36 (Cambria Twp.)  Areas of standing water is almost all gone.  Oh wait…Saturdays rains filled up all of the areas that had been almost dry.
  • CD05 (Danville Twp) Crews are doing great.  Things were progressing great until…. boom, Saturday’s storms.  We are down to two more new crossings and very little remaining tree and brush removal.  I am assuming that tree and brush crews should finish up this week.  Areas of buffer seeding is done and awaiting sprouting grass.  After last Saturday’s storms, there are a few areas that will need to get re-cleaned along the open ditch.  Some areas that will need to be reshaped and possible re-seeded.  We will work through these areas as needed.  Photo below of the equipment lined up waiting for better suited days to clean the ditch again.cd05
  • CD35 (Mapleton Twp.)  Things are still holding well along the open ditch.  What a difference a year makes, given a little drier year than the past 3 or 4 years.

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.
