Help Me Understand This Structure....

Featured Replies

Pool level and current generation schedules. 

Two things I find most folks forget about when looking at reservoir topo maps, yet two absolutely critical elements.

    lets see if this worked remember this is just my opinion, others may view it differently based on their experience...

  • When I think of main points, they are the ones located in the main channel. Secondary points would be those located in creeks. What I would do in addition to what you say, is not only sit shallow and

Fish, ya close!

From the yellow marked "summer" back to & including the areas marked "this is a point" is the entire point.

The yellow area marked "summer" would be good summer, fall, & winter.

I marked the dry land as the point cause its all just 1d to 3d...  just to indicate that there is no secondary points in this map.

The whole point could be a secondary point or a mian lake point depending where it is located. Based on the depth elevation, no distance scale, this appears to be a small area not nore than a long casting distance fron the deepest area to dry land.

I evauate this type of structure without water, adding the water level as it only predicts where the bass maybe located during the seasonal periods.

I have seen at least one tv guy with a big orange hat with T call these secondary points off the main point. So don't get caught up in the terminology. The bass don't care. Recognize it as good structure. If you find cover on it..it just became a little better.

To define this point as "main lake", "primary", or "secondary" is nothing more than speculation without seeing the rest of the map.

Since there are no longitude or latitude lines, giving distances is a wild azz guess.

Given the coloration used it is safe to say the two lines marked in purple is a river/creek channel.

This is a very deceptive portion of a map for the average angler to decipher. If one looks at the bottom right corner there is water on that side as well leading me to think it maybe a peninsula.

So are we ever going to see the rest of the map?

LMB guys love to complicate things. Why are we guessing? The truth is they could be anywhere. You've spent all this $ on fancy FFs, run around for 30 minutes (or more) zig zagging along, mark the place(s) you see fish, and then go catch them. Its how its always been done in the salt. Or are we waiting for one of the pros to name the "technique".

I believe anglers place too much emphasis on 'major points'.

In the 1st place, major points can be pinpointed in a matter of seconds, so they're going to receive the heaviest fishing pressure.

In the 2nd place, a point is no better than the accompanying gradient.

        In other words, I'd rather fish a ledge that adjoins a sharp slope than fish a point with a slow taper.

In the 3rd place, 'inside turns' (pockets) are at least as important as 'outside turns' (points).

        An indentation in contour lines tends to funnel predators and prey, while the action of a point is division (wedge).

        Very often, the best spot on a point will be one of the inside corners at the base of the point.  

 

As Catt alluded to:

1) What was the shoreline elevation (above sea level) when the topographic map was converted to a hydrographic chart.

     And what is the 'current' pool level today?

2) Accurate locational assessments are tough to make without seeing the whole enchilada.

     For example, it's important to know where the river channel is located (assuming it's a manmade impoundment),

     and where the inlet and outlet (dam) is situated. In addition, bottom contour and holding sites are lake-intensive,

     where a mild drop-off on one lake might be considered a super grade on another lake (particularly true on natural lakes).

     Slope values are relative values even within the same lake, so you really need the whole picture

     to distinguish mediocre holding sites from the best 'year-round' holding sites.

Lots of good information fellas... I hope this thread keeps going for another few pages. :smiley:

Can't do much more without knowing where this point is located on this lake and the scale of the map, we know the elevation is 1' increments.

Ok....here you go.  You guys are awesome.  Really appreciate all the input on this map!!!  Just to clarify this point is on the main part of the lake and is probably in the widest portion of the lake.  Can get a lot of boat traffic during the summer.

That puts it into perspective, however you didn't add scale, approx distance length width of the lake area posted?

Your point borders a spawning bay, so it's difinately a good staging area for pre spawner's. The major point across the lake also looks very good for pre spawner's, coves for the bass to spawn. The 3 rd major main lake point is near the dam, good winter and summer for big bass, depending on the baitfish available.

Don't worry about boat traffic, they bother you more than the bass.

The main river channel makes some nice S turns against the points, this creates good structure where undercuts and rocky ledges can hold bass.

The spawning bay next to the major main lake point in question has 2 secondary points close to the little island, the 1st point closest to the island would be another late pre spawn and post spawn spot and the island will hold some bass.

Good looking lake.

Yelp! Wouldn't change anything I've said!

Notice the colored areas for 10, 20, &30'?

That's the shape of the point under water

Where's that 20' hump?

Clue: at the end of the point near the channel

Don't be afraid of the boat traffic, bass in deep water will get accustom to the overhead noise.

Or wait for the moon to rise ;)

Question...between the point in question and the little island to the lower right there is a 20 ft creek channel that goes about a 1/4 way back into the bay before it narrows and comes up. Is that a place you would look in the Summer (night?) Or is that primarily a pre/post spawn spot? Thanks

The creek channel is marked in purple & does not go near the island.

The creek channel is marked in purple & does not go near the island.

Not the main marked channel, the channel/ditch...whatever you want to call it. It looks like a secondary creek channel to me that cuts back through the bay.

That hump looks like fun time with a football jig and a drop shot rig (summer), and the ledges by those flats look nice for jerkbait fishing (try in the coldwater periods/ pre spawn, and in the fall.) The ledges themselves, I would hit during the spawn.

Heres what this entire underwater point would look like from the sides, not exact but close

Ya'll make good POINTS... HHHA! I kill me. :laugh5:

That is not a very good map but if at the land it shows nothing going into this area whuch leads me to think it's not a creek.

I would absolutely graphed it ;)

  • Super User

What latitude is this lake on? The reason I ask, is because you've got quite a bit of deep water compared to shallow spawning areas, should be pretty easy to identify the pre-spawn migration, and eliminate a lot of water, and predict the summer pattern with that info.

  • Super User

If the OP wants to post details of the spawning bay with the island or the opposite main lake point we can reply.

I doubt that there was a creek draining the spawning bay, it does provide deep water access into and out of the bay. The island looks to be connected to the inside secondary point, creating a saddle....

If I wanted to look for a spawning area near that island it would be the little arm below the island.

Why?

It is more protected from winds ;)

Yeah, let's see that entire bay in more detail. This is a very good structure thread.
