Well here is the short of it, and i will try to provide as much detail as I can in a little segment.

My buddy and I are fishing only our 2nd ever tournament this weekend. We chose a lake we have fished all of our lives ( usually only fished it late spring to early fall). we went out to pre-fish this weekend, and the area we usually fish is 10 feet under water.

This is a man-made reservior that usually holds lots of largemouth in sand dunes with sage brush, and beaver huts.

With this much submerged vegetation to hold fish, where do I even start to look for them at?

The reservoir is clear water, surface temp 58-61 degrees the last 2 days.

Just wondering where to look for these fish at, and what styles of fishing to go after them with. We did pick up a few on jig'n'pigs, and 1 on a lizard, but pretty slow compared to normal.

thanks

Is it pre or post spawn? What part of the country are you in? Are they pulling water? What is the weather forcast for the tournament?

pre spawn, northwest US  ( Central washington), they are not pulling water, lake level is pretty steady right now.  Weather forcast is 70 degrees and sunny.  Week leading up to so far has been 68-72 degree's , no clouds, down to about high 30's, low 40's at night

First thing I would do is go back to where you caught your fish. Expand on it. If they were in the sagebrush, what dept. If in 6-8 feet I would start looking for newly flooded  brush on the first flats off the creeks. Into the creeks start with outter points paying paticular attention to the secondary points if they have any brush. If this lake has any grass I would fish the inside grassline and do not be afraid to move back with the fish. With the water on a rise the fish will move with it.If you move back and are only catching small fish back out several feet in depth until you connect with a larger bite. You are probably going to have to cover a lot of water, just slow down when you get bit and cover the area well. If it were me I would stick with the jigs and lizard unless I just could not get bit. I know this is a lot of generalization; however, with out a map to check that's what I would start with having never seen the lake. Good luck.
