Under siege by Invasive Carp?

Ok, Ok, Ok, under siege may be a bit extreme but the invasive carp species seems to be making its way further and further upstream in Minnesota rivers and other waterways.  The Minnesota Department of Natural Resources (DNR) is taking immediate measures after the report of some 50 invasive carp that have been recently caught by fisherman on the Mississippi River.

The Minnesota DNR is working with many other agencies, including multiple federal agencies and some neighboring Wisconsin DNR services to perform larger scale studies and monitoring of these invasive carp species.

The 50 invasive carp where caught by two groups of commercial fishermen while netting along the Mississippi.  The fisherman had suspicion that some of the fish may be invasive species, so the call was made to DNR officials for notification and verification.  The fishermen where near the La Crosse, WI, area when they came across the invasive carp species in their nets.

This isn’t the first reports of invasive carp species in Minnesota or the Mississippi.  It’s said that the invasive carp have been slowly working their way further and further north, even as far north as St. Croix River, or Granite Falls in the Minnesota River, since the 1970’s.  What makes this incident such a big deal is the number caught.  In past situations of capturing invasive species, it wasn’t near the number that were recently captured. Fifty is a big deal to all the fisheries departments that govern our water bodies.

DNR officials and other researchers are predicting that invasive numbers might be heightened because of the high flood stage waters of last spring, where many of the gates along the Mississippi remained open for extended periods of time.

The Minnesota DNR is working with many other partner groups to resolve this issue and to devise new and innovative ways to slow the progression of these invasive species migrating further north.  Invasive carp should be reported to DNR personnel when caught.  DNR personnel ask you, the fisher person, to take a photo and if possible, transport the carp to the nearest DNR fisheries office or to make arrangements for DNR personnel to pick up the suspected fish.

Project Updates:  

  • CD48 (Cambria Twp.)  No new news from last week.
  • JD09 (Le Ray Twp.)  No updates from last week.
  • JD34 (Le Ray Twp.)  No updates from last week.
  • CD05 (Medo and Danville Twps.)  Our contractor for this repair has been officially awarded, we expect repair items to start in the next couple weeks, pending weather.  

  

Recent Drainage Inspections:

  • CD56 (Garden City Twp.)  I was out briefly last Friday, to look at portions of the open ditch along this drainage system.  The ditch for the most part was completely open and flowing nicely.  Water clarity was great and our new phosphorus filter was flowing great.  SWCD staff plan on starting testing again soon.  We performed only one water testing last season before things froze.  The initial test results where great and left us with lots of anticipation for even better results for the near future.
  • Some contractors are looking to get back to digging in the dirt.  We will have a few tile projects projected to start in the next couple weeks.  Road restrictions are on, so moving heavy equipment or any heavy loads can be tricky this time of year.

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.
