F&S contributing editor and expert bass fisherman Mark Hicks reviews six new GPS map systems

Dixon Lake, California--There are lots of reasons why this relatively small water supply reservoir has produced 4 of the top 15 largest bass of all time, including Mac Weakley's recent 25-pound leviathan. According to rangers who work there: 1: The lake has an exploding population of bluegills. 2: The City of Escondido dumps monthly helpings of 3,600 snack-sized rainbow trout into it from November through May. 3: And each spring hatches of ducklings and cootlings provide a high-protein feast for big bucketmouths. All this equals one hot bass fishery, as the following gallery of monster Dixon largemouth photographs proves. Thanks to the Lake Dixon ranger station (www.dixonlake.com) for the pics.

Find one of these bare-bottom patches in a weedy reservoir and you're in for a great day of spring bass fishing.

It's March, and you need to cover lots of water. Stow those soft plastics and reach for a shallow runner
