I have a favorite lake,but its just a big hole that a road construction company used for fill dirt for a road.Thers really no deepth change or structure change to the bottom of the lake.Plus its just a big oval to so no points or anything.There is plenty of logs and limbs in the water,but thats about it far as things to fish.The lake goes from 0-13 max feet in slopes like i said its a big hole.What might i be missing to fish?oh yea its probably like a 5 arce lake.

Try to find the change in bottom composition. That would be the only thing I could think of other than the stuff you have mentioned.

Good luck

a 5 acre lake is small enough to take some time and just cast everywhere, and keep mental notes.  Have you been out there with a depthfinder?  very subtle changes are sometimes all that's needed.

Is the water clear or stained? That could matter significantly as to where you might locate the fish. I'd suggest a modified Carolina rig; using a light bullet sinker above a swivel and about a 2' fluoro leader. Texas rig a 4" Roboworm and just craw the rig around any/all areas you can reach. Sooner or later you'll locate spots that produce consitently. Then you can vary your presentations to see what works best in those locations.

If the water is clear, I'd start off working the shorelines early am. Followed by probing the deeper basin later in the day.

There is your structure 

Sounds like a borrow pit.  Those things are not perfectly flat on the bottom.  Somewhere along the bottom will be some ridges left over from where the buckets were digging out the dirt.  That's what you'll have to find with careful exploration.  I'd suggest doing a lot of dragging with a C-rig if you can't put a boat on it with a depthfinder. 

can you get an underwater camera and a canoe/small boat? might reveal a few surprises.

On bodies of water with limited structure one must hunt for very subtle changes in bottom contour & bottom composition; the unovious becomes significant.

Logs & brush become structure by forming that all important (wall) break line.

Single logs or log piles have a top, bottom, length, and height, any of which will position bass the same as any structure will; single brush, brushes (plural), and brush pile act the same.

Oh by the way these are your "Sweet" spots on bodies of water with abundent bottom structure

Are there any fish in the lake?

If a construction company dug out the pond, there is a roadway, exit , rutted track or something left behind made by dozers and trucks. Walk around the pond and see if you can't find where equipment was driven into the hole from the terrain around the edge. I can guarantee you that no construction company took the time to "smooth" out the bottom. Roadways for trucks are just future roadways for fish!

Get some Christmas trees and put them in a bucket of cement. Then throw them or drag them out into the pond. You just made your own cover. If the lake is as featureless as you say, you will make the fish go to that spot. Look for any contour change or exit road etc, and thats where you should put your trees

Try fishing the areas where the shade transitions into sun, Bass will often seek shade as a form of cover.

I own a lake very similar. 8 acres, little contour changes or structure. You could catch fish all over the lake, but you had to cover alot of ground. Well, starting last year, I starting sinking things. Old trees, toilets, rock piles. The toilet in particular....its about 10 feet deep and right on a point. Anytime I fish, I walk to the dock before I even get on the boat, make 5 casts, catch 3 fish...right offthe top of the porcelain.

That is the proverbial spot on a spot.

Good post Zach.
