      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

New fish consumption advisories for East Metro Lakes....

PFOS present in fish in east metro lakes

by Lorna Benson, Minnesota Public Radio

August 16, 2007

St. Paul, Minn. — When the MPCA discovered PFOS in Lake Calhoun's bluegills the agency wondered if it was an isolated incident or if it represented more widespread PFC contamination. Agency staff quickly expanded their fish sampling - adding 30 lakes to their testing program. They also sampled more fish species including black crappies, largemouth bass and where they could find them, northern pike.

Paul Hoff, who supervises the unit that conducted the sampling, says the new findings have answered that initial question and they have raised others.

"I think what we can say here is the answer is that Calhoun is not alone in having some elevated levels of PFOS. But it's not also typical. We found a range of concentrations out of these first 10 lakes," he said

White Bear LakeFor example fish from three lakes - Bald Eagle, White Bear and Square Lake - had such low levels of PFOS that they didn't trigger a consumption advisory. But the black crappies and large mouth bass sampled from Lake Elmo far exceeded the levels of PFOS found in Lake Calhoun bluegills.

In the case of Lake Elmo, Hoff says it's located near 3M's former disposal site in Oakdale. 3M was the sole manufacturer of PFOS until 2002. The company stopped making the compound after discovering that it had distributed widely throughout the environment.

The Ramsey County lakes covered by the advisory are Como, Phalen, Gervais, Gervais Mill Pond, Round, Keller, Kohlman and Spoon. Besides Lake Elmo, the Washington County lakes affected are Olson, Ravine and Demontreville.

Hoff says most of these other lakes are not near known disposal sites. He says since PFOS was used in more than a dozen stain and water resistant products, it's likely that the chemical is still being used in manufacturing, commercial applications and agriculture.

"We do think that storm water conveyance systems, storm sewers and runoff in the surrounding watershed have something to do it. But a lot depends on the land use and what sort of activity takes place within those watersheds," he says.

But Hoff says he's not ready to rule anything out, including the possibility that the chemical has drifted down to the lakes from atmospheric emissions. People should not stop eating fish from metro lakes because of these latest tests, according to Pat McCann, with the Minnesota Department of Health. McCann says the guidelines are based on the assumption that people consume fish over a lifetime. Because PFOS affects different parts of the body than other chemicals like mercury, there is no evidence that it is more harmful in combination with those chemicals, she says.

"For example PFOS, it has an effect on the hormone levels, thyroid hormone levels or on cholesterol. Whereas mercury is a nervous system toxin, it affects your nervous system. And so those two chemicals react very differently in your body and they don't affect the same systems. So you wouldn't think that they would act in an additive kind of way."

The fish consumption advisories for the 12 east metro lakes range from one meal per week to one meal per month depending on the lake and the fish species. In general the advisory recommends only one meal a week for bluegills, black crappies and other sunfish and one meal per month for large mouth bass. But the guidelines are more restrictive for Lake Elmo where the PFOS concentrations are higher.

Well, I've eaten a few fish out of one of those lakes. I sure hope that itch on my forehead doesn't turn into a third eye... tongue.gif

Man, what are they going to find in the water next?

I find it odd that they did not put Lake Jane on this list. A landfill that has the PFC’s in it is right next to Lake Jane. I wonder if the DNR tested any fish from Lake Jane? I just ate five crappies out of Lake Jane last week and I am not feeling too good! I think I need to see a doctor and a lawyer – just kidding.

I'm generally a free market, pro-business kind of guy, but 3M ought to be hung out to dry for this.

mpester,

I believe they did test Jane, but the lake is "upstream" of the landfill...at the landfill, both the surficial and groundwater movements are away from Jane, so it makes some sense to me that they didn't discover elevated PFOS in that water body. I don't know for 100%, tho.

I would bet the highest concentrations of these chemicals in living organisms (aside from the Mississippi right at the 3M Chemlite site in Cottage Grove where they found outrageous levels in fish last year)could be found in eagle point lake, in Lake Elmo Park. Surface water studies suggest that both the Oakdale and Lake Jane landfills drain to this lake/storm water basin. But since it is not a 'fishing' lake, they didn't sample here.

Hope you feel better smirk.gif

Since Demontreville and Olson were on the list and they are so close to Jane, I would think they were all in the same watershed. The water in Jane looks so much better than the other two so maybe they are not comparable.

I do not have too much to worry about since I only eat about six servings of fish per year. I do worry about my three year old and my pregnant wife drinking the water from the tap with comes from the Oakdale wells.

Olson and demontreville are connected to Jane by a small creek so in one in all three.

Fish are natural filters. I think I'd rather eat fish with chemicals in them than to eat fish out of waters with trash lined shorelines! At least then i would only glow in the dark for a day or two. grin.gif

I'm sure any of us who have fished shorelines in the spring like myself have all seen the nasty washed up on shore form the previous ice fishing season, example, condoms and tampons. Chemicals sound tastier after seeing them.

I bet you there are more lakes affected. I didnt see White Bear, and Bald Eagle on that list. Remember Phalen is included with those in the chain of lakes. I bet when more of the tests come in probably 90% of the lake will be affected in the metro area.

Interesting read at: pubs.acs.org/subscribe/journals/esthag-w/2007/may/science/rr_PFOApeople.html

It appears that your best defense of limiting your perflourinated chemical intake is to reduce your fast food and microwave popcorn consumption.

      I am headed to MN for my annual trip and wanted to target pike on leech. For the past 5-6 years I have been kayaking smaller lakes around the area but now I am back to having a decent boat for bigger waters. Used to fish the east side flats in Headquarters and Boy bay prior to my kayak days. Usual came earlier in the year as well. Bucktails on weedlines still my best bet or do you think crankbaits are the way to go just off weedlines? Better spots than others? Should be there a few days before / after Labor Day.

        I believe the  problem here is a hull with rocker.   At different trim and speed the hull does just that, rocks.   Normally you'd trim in, throttle up and once on plane, throttle back to cruise speed and adjust the trim out.    To be trimmed all in at WOT or even cruising speed would make must hulls plow water at the bow.   In the case with rocker you usually find the porpoise stops when you increase speed.   The fin might be enough to lift the transom up and stabilize it.   Let us know what you do and how it works.

      Went and tried a new spot... 3 snacky cats. One of them took my rod straight into the river and I had to dive in after it. Good times.

      I use the Daiwa ct r also have 2 of them best out there in my opinion.
    • FishinCT
      Pretty good for me from Monday through Wednesday. Found them from 14-24ft depending on the spot but most fish came from under 20ft. Trust the electronics and motor around til you find a good school. They are hitting pretty well when you find them

      Best wishes for a happy retirement Ace.   I could never have done the guide thing even if I were a good enough fisherman.   It takes a special type of person to deal with all the different people... Congratulations on a job well done.

      Terry, Sorry to hear that you have to retire after all of these years! I suppose It will be my turn to join you and Tommy before to many years also. See you on the water!! Cliff

      Congratulations on job well done sir. Your deserve time for yerself with Sandra an the whole younger crew. You have always been nice to me an a big help when I first seriously did the Muskie fish guide deal back summer 1996. We have had some fun times laughing online an in each other's boat over the years. Even boated a fish or three an coined a few major phrases still used in today's ever so silly online Muskie fish market.  Good stuff that I think only you n I could muster up and never take any of it seriously. Truely makes me smile clear to my middle all the junk we talked about an did. You are a good man Terry and welcome in my boat any time. Anytime. Ya done good and will not soon be forgotten. Thanks for being my friend on or off the water. The name fits as you really have been "The Ace"on our sweet Vermilion.   Still no fish round my docks but Bonnie, Polar Bear Boy an myself always have enjoyed your company. Yer the best in many ways my friend.  Thanks. Keep on Rocken!   Tommy.       PS.    I will continue to keep the Zombie Horde in check.    ; )
