Drainage update 8/10/2020

 

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.                                                                                                                                  

Catfish Data:

The Minnesota Department of Natural Resources, or DNR, is doing their homework on catfish species in the Minnesota River.  For those of us that are outdoor enthusiasts and fellow fisher people, catfishing is a special treat.  When fishing the river every bite is an adventure, not knowing for sure what species of fish may be on the other end of your line. 

A three-person team from the Minnesota DNR has been putting in working and studying Channel Catfish and Flathead Catfish since around 2016.  The DNR crew has been tagging the Flathead Catfish with a tracking device called a P.I.T., or a passive integrated transponder.  2020 tagging operations are put on hold because of social distancing constraints but they hope to resume next year.

In 2019, crews covered over 70 miles of Minnesota River, concentrated mostly in the Redwood Falls and New Ulm area.  The P.I.T. tags are much like what a veterinarian would put in your favorite cat or dog.  The tag has an identification number with additional information of original capture location, weigh and length.  Each time the catfish with the tag is caught, the information is recorded and then updated.  Flathead Catfish caught without a P.I.T. tag will have one implanted at the time of capture. 

The Minnesota DNR crew is hoping that the long-term study will give valuable insight into the life and state of health of this catfish species.  The data of the catfish species will also give valuable insight into the overall fisheries health in the river system.

Project Updates:  

  • JD34 (LeRay Twp.)  No change from last week.
  • CD05 (Medo and Danville Twps.)  Crews should be getting back to ditch cleaning and outlet repairs this week, pending weather.
  • JD09 North (LeRay Twp.)  No change from last week.
  • CD48 (Cambria Twp.)  Fall checklist items remain.

Recent Drainage Inspections:

  • CD56 (Garden City Twp.)  Tile repairs have been made.  There is still some water standing in areas and lots of muddy areas from the large rainfall two weeks ago.  Things dried up just enough to get the tile repairs done.drone
  • JD17 (Garden City Twp.A new 6-inch dual wall hdpe tile will be installed in the next couple weeks.  Most of this tile will be in the north / south township road area.  The new tile will also include two new in-takes, one on each side of the road.
  • JD48 Brown (Butternut Twp.)  Last week we used a drone to fly and map out any potential areas in need of repair.  The drone is an extremely useful tool in pin-pointing and mapping out repair areas, versus using a four-wheeler, especially this time of year when grasses are very tall.
  • CD05 (Danville Twp) Not much activity last week on this job site.  More areas of sloughing have been identified and will need to be re-cleaned.
  • JD116 Martin and Faribault (Pleasant Mound Twp.)  Crews started cutting and grubbing out trees along the buffer area to portions along the open ditch.  Specialized machinery was used for some of the brush and tree removal.  Ditch cleaning will start sometime soon.  This ditch system, along with two other public open ditch systems will be cleaned this year.jd116
  • CD35 (Mapleton Twp.)  A small amount of open ditch cleaning might be needed, just to a small area along the north / south portion of open ditch.

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.
