us army corps of engineers website. you can download and print each map page from the 2001 navigation chart book. The Terraserver or google earth sites will show you current photos of the areas for a little better idea of what you will see on the water. the hot spot maps are not as current as what you will get by using this method.

I have seen the Sponsor Teams (networks) having their rpe-tournament strategy meetings at larger events. They tend to work tosgether sharing patterns and sections of larger bodies of water. They usually include the fishermen that share common sponsorships, ie: boat or motor mfg’s or some other common sponsor or element that would cause them to want to share info.
If you are not on a team you have to work harder to compete with the combined hours on the water that the group accumulates to eliminate sections of a body of water or specific patterns, colors, bait types etc.
