HI Group, just have a few questions regarding the lake info on the MN DNR site. Is this info correct for the most part? And how do you figure it out. I will give you an example.

Length of Selected Species Sampled for All Gear for the 2001 Survey Year
Number of fish caught in each category (inches)
Species 0-5 6-8 9-11 12-14 15-19 20-24 25-29 >29 Total
Black Crappie 0 16 14 0 0 0 0 0 30
Bluegill 329 125 1 0 0 0 0 0 455
Brown Bullhead 1 2 13 4 0 0 0 0 20
Green Sunfish 2 0 0 0 0 0 0 0 2
Hybrid Sunfish 38 34 0 0 0 0 0 0 72
Largemouth Bass 3 5 3 7 4 0 0 0 22
Northern Pike 0 0 0 0 9 45 27 9 90
Pumpkinseed Sunfish 95 30 0 0 0 0 0 0 125
Rock Bass 31 60 32 0 0 0 0 0 123
Tullibee (Cisco) 0 96 53 23 0 0 0 0 172
Walleye 0 3 21 28 28 18 11 0 109
Yellow Bullhead 0 11 58 21 1 0 0 0 91
Yellow Perch 175 172 5 0 0 0 0 0 352


Ok it didn't turn out the way it was on the other page. But I think you get the idea. Anyways what I am asking, is this the average fish caught on the lake? And if so the bass fishing doesn't look so hot. I mean how can you tell by these maps if a lake is any good for Bass fishing or not.

Not sure what lake your talking about but this lake according to the information provided has no Smallmouth Bass that were netted during the last DNR survey it has few LargeMouth Bass of different lengths, it seems to be more of a Sunfish and Walleye lake from what I can tell.

So you have the species followed by the number of fish and length of each fish found in the DNR traps/nets during the last survey "2001" the nets/traps are placed at varius locations for a set time.

You have to look at the type of trap they used for the survey. Traps in general do not work well with bass, they have to use electrofishing, using electricity to stun the fish, and not used very often at all.

Next time you are looking at a lakefinder survey, click on the gear used link above the type of trap(s) they used and it will explain it.

Length of Selected Species Sampled for All Gear

That was at the top of the list. I thought it meant that they were taking the average caught fish from those who fish on the lake. As for what lake that was, it was Gull lake in Cass county. I went to that one because a few guys on here said it was a great Bass fishing lake. And I wanted to see how many the DNR said were in there. But from what you say the traps are not really good for Bass?

frawri,

I don't care what the results are for DNR netting... Gull is an excellent Largemouth lake. I have consistently pulled 5 lbers out of that lake. It is prime waters, especially early in the season.

Gull is part of the Gull Lake Reservoir chain of lakes. The lake has a maximum depth of 80 feet and about 30% of the lake is shallower than 15 feet. This means it is great for bass. Water clarity is excellent.

The most recent population assessment found northern pike present in good numbers. Size ranged from 17.5-39.8 inches and over 50% of pike sampled were at least 24 inches in length. Walleyes as large as 29.2 inches were sampled and 27% of the catch were at least 20 inches in length. Fry stocked the past three years, along with natural reproduction has created an excellent outlook for walleye fishing in the future.

Largemouth bass catches ranged from 5.3-17.6 inches, with numerous age classes present. Black crappie numbers remain high and bluegill numbers moderate.

Before I noticed which lake this was from, here was my take on those numbers….

Fair crappie numbers with an “average” average size.
Good bluegill numbers, with some decent fish mixed in
Big bullheads are present
Looks to be an excellent largemouth lake
Good numbers of pike with excellent average size
Excellent cisco population
Good numbers of walleyes with a nice mix of sizes
Good numbers of perch with a few decent ones mixed in

I’ve been looking at these surveys for a long time. After awhile, you can usually interpret them fairly well, but by no means are they a perfect tool to use. Like was already stated, largemouth don’t show well in these types of surveys. The numbers in this survey and the size in this survey are much better than most lakes. Knowing after the fact that this survey is from Gull Lake makes me believe that my interpretation was fairly accurate.

If you want to get an idea of how to interpret these surveys, here’s what I would do. Pick some lakes that you know very well. Pull up the surveys for them and correlate that information to what you know to be true about the lake. If you do this, you’ll be able to take a lot more information from those surveys than if you’re looking at them for the first time or if you aren’t very familiar with them.

Good advice AWH. I've done the same thing. When I read 'em, it points more to the strengths then to the numbers. I used to fish Gull too and had a blast catching bucketmouths. Caught 'eyes too but back then,I pretty much did bassin'. What worked for me? Leeches on floaters, believe it or not. Of course, I may be dating mayself somewhat, but that was probably the early to mid 80s.
