Thought I would chime in with some info from someone that was there once. I was one of these inspectors the very first year the decontamination units came out (2012). I was a recent natural resources college graduate (28yrs old) looking to get in with the dnr and thought this would be a good way since 90% of their positions are for internal hire. We had 2 days of training at the headquarters in St. Paul, went thru a booklet of things to look for in and on boats and questions to ask people and then the 2nd day was mainly learning how to drive with the decon trailer. It was amazing how many people could not back up the trailer while having to zig zag between cones!! I was stationed out of the Rochester office and covered the river, which did not make sense. I covered baypoint, colvill and hok-si-la. While the crew from Frontenac had the rueshen landing on the south end of lake city and lake zumbro…
I did not understand myself what lake it mattered that someone fished last if they were putting in on the river which has just about every invasive in it, so I mainly just watched as people came by to see if they had shown up with their boat plug in and advised them if they did that it was illegal. I was more concerned with where they thought they would go next, if it was somewhere that did not have an invasive in it. We probably used the decon unit probably a dozen times throughout the summer. As far as changing the water on bait, this one still bothers me, A person is automatically assumed guilty of having changed water on their minnows or leeches. If I could obviously see that they did not have their bait in river water I let them keep it, (pretty easy to tell).
We quickly realized that most of the people we encountered mainly fished or boated on the river, so that made our job easier. We got to know people and most were friendly, even helped a repeat guy at the hok-si-la landing change out his blown out trailer tire for him, (he had just recently had knee surgery). Also had to call the water patrol for a guy who had tip over his inflatable sail catamaran out in the middle of the river and could not get the sail back up. I did the job the way I thought was right and made sense versus some of the non sense they have set in place, That was the only year I did it and gave up on trying to get in with the dnr and am currently working on taking my state electrical journeyman wireman test this fall.
