988-acre lake near Garden County. Nebraska Game and Parks Commission survey water. The lake tops out around 7 ft. The depth chart is built from real state fisheries GPS surveys, so the humps, channels and drop-offs you see are measured, not guessed. The rest of this page walks each species through its year, using the map's own scoring.
On the chart, Island Lake draws 988 acres inside 4.7 miles of shoreline. Nearly circular (index 1.1), so the story is the bottom, not the bank. Nothing on this chart breaks 15 ft, which makes the whole surface littoral: weeds, bait and ambush cover everywhere. Figure 1.6 mi of water from one end to the other, 1.2 mi at the beam. You'll find it in Garden County. For a second option, Crescent Lake lies 2 mi south.
Spring walleye on Island Lake hold shallow, usually 2 to 7 ft. Depth-wise the year is flat: 2 to 7 ft in summer, 2 to 7 ft once it turns cold.

The summer box starts with a crawler harness on bottom bouncer or a deep crankbait (trolled).
