It's not really a lack of fish persay...

The recent cold weather has still kept the water temps a few degrees below what it needs to be for bass to move up in the shallows. They are very sluggish because of this cold water, so if you do try and go out, try and fish smaller lakes and ponds and find warmer water and then present your lures very slowly....

Weightless rig any plastics and what not.

I went out last night and got 3 bass out of a tiny pond (not very big bass, but bass nonetheless) and in another pond I've already had a 3 lber smack a spinnerbait in 4 feet of water...

Go out on a warm sunsoaked day and try and fish the shallow water for some bass. Give it two weeks and the bass should all be in the prespawn pattern looking for beds and what not...

Good luck
