How do you use a lake map to locate fish?

10 posts in this topic

I am sure this has came up before but is there anything on the internet or anything? Or just out of personal reference? What do you look for when searching for walleye.

Breaking down a lake on the kitchen table is an effective way to help eliminate water but there is no replacement for being there. However, some things to look for on a map are tight countour lines (i.e. steep break lines or drop-offs) near main lake points or long stretches of shoreline, any "neck down" or funnel areas, creek, stream or river inlets/outlets, mid-lake structure adjacent to deep water and emergent or submergent vegetation.

Look for flats out along points, which usually hold fish. As well as the drop offs following that. Steep drop offs, trees, rock piles, different bottom contuer all come into play.

I do the same thing every year. I get out my Hot Spots map on the kitchen table with my Sharpie and plan out dozens of great spots I want to try on Cass Lake which is where we have been going for 20+ years. Then when I get up there I find myself going to the same 3 or 4 spots that I have been going to for my entire life. Not sure if you can teach an old dog new tricks!!!

Now that the water is warming up fish will be moving deeper and I like to look for " butterflys" they are pronounced areas where two peices of structure come together and between them is a saddle. If you look at the contour lines this will appear as an "X" or a butterfly. Check em out you might be suprised. There are lots of them on the big water. good luck.

Got a follow-up for this question. How often do you buy new maps? Structure changes often, especially in heavily traveled lakes.

I used a map from about 10 years ago, trying multiple spots on it, hoping to find some accuracy, and only landed a few small bass in various places (Not necessarily looking for bass).

I picked up a map at Dick's for a quick browse and chose two spots that looked good about two weeks ago. Went back to the lake, tried both spots, and both of them produced fish. All fish they produced were what the map said they should be, as well.

So I'm not saying that the spots already listed on the maps are more accurate, but I feel the maps in general are probably a lot better. Bringing back to the original question - about how often do you replace them?

I'm not sure I follow you on structure changing on heavily traveled lakes? The only waterways that typically change are rivers due to the current/volume of water flowing.

I was unaware of this apparently. Well, I know it changes in rivers, but I figure there would be some variation over a course of say, ten years, especially in a shallower bay or lake.

Specifically, I know of a few deep (15-20') holes on Tonka that have seemed to be filled in (Now 5-10') over the years.

Is there no reason to update maps?

    • Yep.  We all will.  I already said that.
    • Holy cats!   I mean bullies!
    • Not looking good for The Donald.
    • Yes, good times! There is adventure to be had but it has to be looked for.  Just getting to know the area has been one adventure and now the second one is finding out who plays where when the playing actually starts.    I could've used one of these on Saturday.
    • Trump and Clinton are 'tied' in Minnesota, says poll that's wrong Tuesday, September 27, 2016 by Mike Mullen in News Donald Trump and Hillary Clinton are TIED in Minnesota! Can you believe it? Don't!NBC News Hillary Clinton and Donald Trump debated Monday night.    Tuesday morning's conventional wisdom says the debate was long on losers -- Lester Holt, Chicago, the truth -- and produced only one winner: Barron Trump, 10, who is reputed to be "so good with these computers, it's unbelievable."  Ignore the spin. Let's pay closer attention to something tangible, something real. Like this tangible, really bad poll paid for by Breitbart News and believed by no one. Trump and Clinton are in a dead heat in Minnesota, tied 43 percent to 43 percent, according to an "EXCLUSIVE" poll conducted this past weekend. Simultaneous polls in Pennsylvania and North Carolina found Trump tightening on Clinton's leads, with her tiny advantages in both states falling inside the margin of error.  "Minnesota is the perfect example" of Trump's nationwide surge, says pollster Pat Cadell, the spooky-looking punditFox News often wheels out after applying shoe polish to his head. Cadell continued: “Minnesota has been a close state in past elections, even though the Democrats always seem to win it, it was close in 2000 and 2004." This would be a good point. If it weren't a bad point. Those old elections reveal that Democratic candidates, even lame ones, tend to overperform their national average in Minnesota. In 2000, George W. Bush lost the national popular vote, 47.9 percent to Al Gore's 48.4; in Minnesota, Bush got 45.5 percent to Gore's 47.9 percent. (More than 5 percent of Minnesotans voted Ralph Nader.) In 2004, John Kerry won Minnesota with 51 percent to Bush's 47.6. Nationwide, Bush won by 50.7 percent to Kerry's 48.3 percent. Point is: If a Republican managed to win Minnesota, it won't matter, because he'll have won the rest of the country in a landslide.    Here are some fun stories about Gravis Marketing, the polling company that inked an exclusive -- "EXCLUSIVE" -- deal to do Breitbart's polling this campaign season. It seems Gravis has a history of shading results just a liiiiitlebit in favor of flamboyant, Tea Party-style outsiders challenging inside-the-Beltway incumbents. (Scenario sound familiar?) In Kentucky, Gravis had GOP U.S. Sen. Mitch McConnell at 48 percent, and his wacky Republican primary opponent at 34 percent; McConnell won 60 percent to 35 percent. In Texas, GOP U.S. Sen. John Cornyn had a 43-28 lead over a fringe-right candidate, whom Gravis described as "gaining." Cornyn won 59-19.  Those blown calls had Slate calling Gravis "the worst poll in America." It gets worse. This year, in Maryland, Gravis conducted a Congressional poll for yet another conservative outsider, and found the right-wing challenger winning 58 percent to the incumbent's 29 percent; in fact, the incumbent won, 78 percent to 11 percent, a difference of 96 percent from what Gravis had.  Probably, Hillary's ahead of Trump by something by something like the results in a recent Star Tribune poll (44 percent to 38 percent) or this week's Survey USA/KSTP results (Clinton 46 percent, Trump 39).  But if Gravis is as wrong as they've been in the past... maybe Clinton's ahead 75-25. Or 92-8! 95-25? Trying to adjust for numbers collected by the wiz kids at Gravis for the mouthbreathers at Breitbart is virtually impossible. Not the sort of math you can do in your head. Quickly, Barron! To the computer!
    • Which side of the rope are you asking about??? The one end is a surgeons loop(with the magnet). The other is just the way I learned as a kid in scouts to quickly secure a rope so that it didn't get tangled up and could quickly be redeployed. Loop it several times to take up the slack. Then wrap the tag end around several times and pass the last few inches back under itself. Pull it snug. When you need to use it just pull the tag end free and unwrap. Don't know that it has a name.?.?.?
