Id agree that Catt and Nitro's discussion would apply in bodies of water that contain different compositions and cover on structure, but what about lakes and ponds that are just a sand bowl, or made up of nothing but rock left by the glaciers during the ice age? lakes that have absolutely no change in bottoms "composition" whatsoever? depth becomes composition
I'll give you that this happens mostly in northern states with colder climates,
..On such waters bass seem to gravitate to changes in depth,... in sandbowls locating themselves for easiest access to forage, as say a river channels entrance to the lake, or the depth baitfish are holding at. on rock formed lakes they hold tight to the huge boulders for chasing baitfish, and can be anywhere when targeting crayfish.
On such lakes the bass actually do spawn. feed, and live in the exact same areas.,... It's the usually subtle changes in depth that will attract them, and when you find those sublties,. Largemouth are there 24/7 moving slightly (maybe as much as 100 yards) depending on wind, sun, or current and smallmouths varying a bit more,.. kinda like nomads.. Now the game is a little different. It isn't as easy as fishing a defined change in composition on structure, knowing where they are, and what they are feeding on,..you need to now figure out what they relating to in that "subtle" change and why,... like finding a pattern within a pattern,. focusing your attention just a little more. Making it even harder is the fact that "most" of these bodies of water have extremely gin clear water. Usually, these fish see you before you find them, you'll NEED to pre-fish it well, make extremely long casts to that pinpointed "pattern within a pattern" and pay even more attention to the present conditions due to lack of demonstrative cover. When god above flicks that preverbial "switch" and what was working, now fails?,... On such lakes its a more difficult task to figure out whats going to work now, usually the fish will either suspend and shut down, or hold tight to the bottom and either reluctantly hit with great predjudice, or clam up. It's that reluctant hit thats tough to figure out. They dont have the availability of hiding in the weeds, or to snuggle up to a brushpile, or suspend under docks,...these three arent there.
Many of you may be saying to yourself,, "whats the difference, change is change, be it subtle or definatve, id still fish it the same",... I understand your thoughts,... the difference is: first,... finding the subtle change is harder to do, secondly,.. its usually not like fishing a weedline as you feel the weeds then not,, or flipping docks you can see, or carolina rigging a drop that you feel the weight drop,. The "subtle" change may be a single cooler sized rock on a very slight depth change,.. or a different color in the sand that the darker color holds warmth better, or the presence of a short growing weed on the bottom. etc: the subtle is just that, finding it isnt as easy as you may think
Just as bass are "oppurtunistic" in lakes with a great biodiversity of cover and structure,.. they are still the same species in lakes with no biodiversity or compsition changes at all,...just that they are in a different neighborhood and react a bit different to survive. they have no choice
just my opinion from what i've observed, im no professor.,...... so please dont shoot!,...lol ,...I really find this type of discussion very interesting and welcome any replies,..positive or negative alike
