      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 .

planimetered vs. littoral?

Recommended Posts

I have noticed that when lake acreage is specified, occasionally there are two values mentioned. For example, Lake Osakis is defined as being a little over 6,200 acres planimtered but just over 3,400 acres littoral. Anyone know what these terms mean?

Planimetered acres refers to the size of the lake shoreline measured off an air photo. Littoral acres is the area of a lake less than 15 feet deep. This is a very subjective number. It is suppose to represent the portion of a lake where vegetation grows. Well we all know lakes where vegetation grows much deeper, but 15 feet is the number used by the DNR.

I understood that littoral area was the area of the lake where light could reach the bottom. This would take into account the clarity of the water. I could be wrong but thats what I thought.

This is my understanding from all the lake maps that I have ever seen.

Both are correct. The Littoral Zone is technically the area where plant life can survive in a lake - which is how deep light penetrates. But the way the DNR ESTIMATES the littoral area of a lake is by calculating the surface area of the lake that is 15 feet deep or less. This is a rough estimate, to be sure, but it's better than nothing. You can't base it on transparency because that can vary from day to day; some lakes have a transparency of 20 feet in June and 6 inches in August. They need to have an idea of what the littoral area is because that's what determines how many fish the lake can support. All fish stocking is done on the basis of littoral acres, for example they'll stock 6.5 pounds of fry per littoral acre. Lakes that drop straight down from the shore into 100 feet of water can't support as many fish as a gently-sloping lake of equal size because there isn't enough aquatic vegetation to grow insects and crustaceans.

This is actually very useful information. For example, if one was previewing a lake where the littoral area was only about 10% of the planimetered, you could draw a couple conclusions. 1. The fish will likely be concentrated into very specific areas and 2. The reproductive potential of the lake may very well be low.
