Drainage update 9/25/2017
Upcoming Drainage Hearings or Meetings:
JD34 (Le Ray Twp.) Preconstruction meeting will be held on September 27th. This preconstruction meeting is for those
individuals that will be affected by the upcoming drainage improvement project
in Le Ray Township. Those landowners
affected by this project should be receiving notice in the mail with details of
times and locations of this preconstruction meeting.
Twp.) We will be holding a landowner meeting
to discuss costs associated with ongoing issues along the open ditch of this
City Twp.) The contractor has finished all
major aspects of this repair project.
The new concrete culvert crossing along 499 Avenue in Lincoln Township is in and complete.
The contractor is finishing up with a few “check list” items before
calling this repair project complete.
Seeding contractors should be finishing up any additional seeding
in the next week or two.
We (Blue Earth County Drainage Department) have been seeing a huge increase in beaver-related issues this year. We currently have five drainage systems with active beaver complaints.
Beavers are often thought of as cute and cuddly looking with their fury
round bodies. Did you know that an adult beaver can chew through a six inch tree in 15 minutes? Lately the beaver
populations have made a drastic increase.
Some say the spike in populations is due in part to the decreased demand
for furs, so many people don’t trap beaver as much anymore. Despite their cute looks, beaver can be very
destructive to people’s property and structures.
I was reading through some different articles
on beavers and how to manage them. Turns
out there is some equipment the common person can purchase or actions they can take to prevent or
minimize damage to property or trees. Some
of the easiest ideas include wrapping your trees close to the water’s edge
with wire mesh or using electric fence methods to detour the beavers from
getting close to your trees or property.
Beavers will often make dams out of the trees they cut down and the mud
they collect. These dams often cause
others issues especially when they are blocking the flow of rivers, streams and
drainage ditches. It’s not just as
simple as pulling the dam apart or out of the way. Trust me from past experience, if you don’t
remove the beaver or beavers first, they will rebuild that dam in very short
time - often in the relatively same area.
Removal methods usually include trapping the beaver. There is a designated trapping season which
includes beaver and other furry animals in Minnesota, but what happens if the
damage is occurring outside of that trapping season? If trappers are taking beaver in regular
trapping season, no additional permits are required. Under Minnesota State Statute, beavers can be
trapped or removed without a permit during legal trapping
Outside of the season, if the beaver is causing damage,
the property owner or legal occupant has the right to remove the beaver if four
conditions are met.
1. Landowner / occupant must have beaver damage to said property
2. Landowner / occupant must authorize such removal of beaver
3. The beaver must be trapped or removed on such said landowner / occupant’s
property where it is causing such damage stated.
4. The person taking the beaver must notify the DNR (Department of Natural
Resources) within 24 hours, and conform with additional reporting requirements.
State, County or any other local
government employees, while on duty representing such organization, do not need
permits for beaver removal on lands under their jurisdiction.

I have several photos below showing some most recent issues with beavers
in just the last month on drainage ditches around the area.
The picture to the left is a CD56 culvert as of Tuesday 9/22/17...picture to the right is same culvert crossing two days after removing the dam in picture to the left. The beavers that were not trapped (there were multiple beavers) rebuilt the dam in 48 hours within 30 feet of first dam.
These two photos are of a large beaver dam on CD86. It's hard to tell its size from my pictures but there's 4-6 feet of water being held back behind that beaver dam.
Recent Drainage Inspections – week of September 18 – September 22:
Please call with issues you observe on our
public drainage system, as there is a lot of open ditch and tile in our county
and only two of us in the drainage department. We will do our absolute
best to service your issues and concerns as we receive them.
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.
