Post Spawn Flathead Cat Location?

10 posts in this topic

Still trying to learn the ropes as is this is my first summer after cats. I had good luck pre-spawn, nothing huge but ok fish and decent numbers in backwater timbered areas of the Mississippi. Now I know that the post-spawn bite is much tougher, but I've had a string of zero's now and am wondering if I should still be sticking with those same backwater spots, or be moving to more main river structure? Any general advice about fish location now post spawn that I should be keying in on? Thanks for any help you can offer.

I would stick to main river spots. Big cats need a lot of oxygen, and I don't think the backwaters are the best place for that right now.

I wouldn't be to alarmed by getting skunked a couple times out. Last year I had 12 outings in a row when I didn't catch anything, while others in my boat have. This year I believe I went 8 or 9 outings in a row with out a flat. As of today, I have a skunk egg for the last 2 nights out. I have been catching my fish in or on the current seams. The slack water has been dead for me as of late, probably for the reasons Ed stated. I dont let those 0'fer outings effect me much, because I know I will catch some in due time. Post spawn for me has been always slower, I will still catch decent fish, I just wont get a 10 fish night.

There are two very interesting flathead tracking studies that were done at well known universities that provde a wealth of understanding about post-spawn flatheads. The 2006 Catfish In-Sider has a good article that sums up a study done on the St Joseph River in Michigan. I've paid close attention to this one because I believe the St Croix River fishes a lot like the St Joseph River.

The key points of that study suggest you need to make a significant shift from your pre-spawn flathead fishing locations. One major shift that you will find hard to follow is to move from fishing deep water to zeroing in on water shallower that 9 feet. The study found that the presence of deep water was a minor factor for determining flathead catfish location during the bulk of the open water season. In fact their research showed that St Joe cats have a distinct preference for water shallower than 9 feet for use as a home base in spring, summer and fall. They found that large adult flatheads would locate in sizeable logjams and would establish this as a home base. They then become intimately familiar with the lay of their neighborhoods. Big cats spend their feeding hours roaming well-known areas close to home. They advised when prospecting new water for big fish, stay within about 75 yards of any sizeable woody structure. A lot of this information from Michigan supports another study done in Missouri and when comparing the information from both studies you may shift how you fish during this time of year. At least I have. Here are some thing to consider based on the research:

#1 - The presence of deep water was a minor factor for determining flathead catfish location during the bulk of the open water season. St Joe cats have a distinct preference for water shallower than 9 feet for use as a home base in spring, summer and fall.

$2 -Flatheads chose mild, main river currents for their hunting grounds and stayed out of backwater areas.

#3- The trend was to move out from cover toward relatively shallow (less than 10 feet) open areas to feed.

#4- During daylight hours, they remained in logjams and other woody debris and showed little movement.

#5-This is important - Summertime flatheads are active for about an hour in total throughout a 24-hour period.

#6-During the 24-hour continuous tracking, fish movement consisted of extended period of inactivity puntuated by quick, discrete movements to distinct physical habitat features such as log complexes, single submerged logs, or clay ponts. Discrete movements were essentially straight-line, anthough some movements arced along cutbanks. The length of the movement paths ranged from 480 to 5,126 feet.

#7- 24-hour continuous tracking found flathead activity from noon thruogh 2:00pm. A second period of increased activity occurred between sunset throgh 11:00pm. Activity increased again from 1:00am to sunrise.

Interesting stuff - I hope this help you.

great info just one quick question what a clay pont? Is it a under water clay flat or point?

I believe it is exactly that - the bottom is that hard clay with some type of washout area that creates a point. I haven't found that on the St Croix but I would think the Minnesota River would have a number of spots like that.

thats what I thought I have run into those spots a few times on the river and the fishing is or can be really good might have to see what they look like now that the river is low but after recent rains that may change my game plan a bit.

Thanks Steve

    • BEFORE BEGINNING

      Before you begin, make sure you have a good strong battery and make sure it's charged up. If you have a bad or weak battery, you may want to replace it because if it doesn't crank good and strong, you are likely to get a low, inaccurate reading. Make sure your engine is warmed up to operating temperature(if possible). About 10 minutes of riding should do.

      First, take out the spark plug and thread in the adapter for the compression tester. Make sure you have the correct size adapter for your particular ATV. Slide your kill switch to the "off" position. Some ATVs won't crank over with the kill switch in the "off" position, so if yours is like this, then you will need to either unhook your ignition coil or ground the end of the spark plug wire to a good ground. You can use a jumper wire with alligator clips on each end to ground it. Next, make sure the throttle is in the wide open position. You can either hold the throttle lever with your thumb or you may be able to tape it or use a zip tie to fasten it to your handlebars to hold it in the wide open position. If you don't have the throttle in the wide open position, you will probably get too low of a reading. Also, if you are testing a newly rebuilt engine, the engine needs to have been run for, at least, 30 or 40 minutes or you will probably get too low of a reading.

      NOTE: Before you begin with the actual test, make sure the threaded adapter is screwed in good and isn't leaking any air out around it.

      ACTUAL TESTING

      With the throttle in the wide open position, push the start button and crank the engine over until the hand on the gauge stops moving. Each time the engine turns over the hand should raise a little more until it reaches the maximum compression of the engine. When it stops, that is your compression reading. This usually takes no more than 10 seconds. Try to avoid cranking an engine for more than 10 seconds at a time as this is hard on the starter and the battery. Now, push the relief valve on your compression gauge and that will reset the hand back to zero. It's a good ideal to repeat the test a couple or three times to make sure you get an accurate reading. On kick start models, it will be the same procedure, but obviously you will be kicking it over instead of using a start button. Worn piston rings and cylinder walls will increase the number of strokes it takes to reach the maximum reading. If you're kicking, it could possibly take as many as 10-20 kicks to get the highest reading.

      THE READING

      You will need to check your repair manual for your particular model for the correct compression specifications. See note below. Usually, an engine will run OK if it has at least 100 PSI of compression. Most engines will have somewhere between 100-250 and some as high as 300 PSI, depending on the engine. Sometimes they will run with under 100 PSI, but usually not very well. If you get a low reading, you can do a "wet test" to try to help determine the problem.

      If your reading is too high, then you probably have carbon built up on your piston and combustion chamber.

      NOTE: You may get a low reading on some engines because some engines have a decompressor assembly built into the camshaft. Check the service manual for your quad to see whether or not your quad has a decompressor assembly built into the cam.

      WET TEST

      If you got a low reading, pour about 1-2 teaspoons of clean motor oil down into the cylinder through the spark plug hole and do the compression test again. If your reading increases, then your rings or cylinder walls are probably worn. If your reading doesn't increase, then it's probably your valves. You could have a bent valve, you may have leaky valve seats, or your valve clearance may not be adjusted properly. Also, low compression can be caused by a blown head gasket.

      CAUSES OF LOW COMPRESSION

      *Worn piston rings or worn or damaged cylinder walls
      *Leaking valves
      *Valve clearance not properly set
      *Blown head gasket

      CAUSE OF HIGH COMPRESSION (stock engines)

      *Carbon buildup in combustion chamber and on piston

      NOTE: Compression testing is a good way to keep track or "gauge" the wear in your engine. When you first get your ATV or when you rebuild the engine in your ATV, you can do a compression test and then later on, you can do them periodically. This will help you determine the wear in your engine each time you do a compression test and will guide you in knowing when your engine needs rebuilding.

      This is about all I can think of. I hope I didn't leave anything out and I hope this helps everyone with their compression tests.
    • As dumb as this sounds how is this done?
    • Try a compression check. And make sure the choke is opening all the way.
    • They are not the best out their but for the price and your average person not too bad I guess, Its going to send lead to where its pointed. This is probably what is going to happen he is going to buy a package shoot it for awhile then start upgrading everything to how he wants it and it is going to end up costing way more than if he just built one himself how he wants it.  
    • Hello, well I convinced my brother in-law to pick up my buddies old 1980 185 although pretty sure he said it was bored out to a 200? Here is the deal it's been sitting for a solid 8 years. I know it ran fine before. Not the delema-----   It starts right up (he bought a new carb odd amazon) although it sounds like a jet with high rpms. Looked at the throttle cable that's fine. Floats are fine. So he plugged this hole in the air filter and got it to idle down although when he hit the gas wouldn't get any power. Read a few things online and they tell you to just bypass the filter box and all that so back to amazon we went to get one of those filters that mount right up to the carb and it's still the same issue..   I just haven't seen anything like this? Do you guys have any thoughts or tricks that we/he could try?! Thanks in advance
    • Hi Everyone,  I'm looking into buying my first true fish finder and I'm a little perplex with the mapping card situation.  I'm looking at Humminbird Helix 5's and 7's.  I'm drawn to the autochart feature.  From my understanding, you can record 8 hours of charting onto the internal storage, but, is there any native mapping included on the unit or do I absolutely have to get some sort of mapping chip, zerolines or lake master, or navionics?  Can I store data on a blank SD card?  I've been researching this a lot and haven't found any conclusive answers. Thanks everyone!
