Indiana lake depth maps

Fletcher Lake depth map

Fletcher Lake in Fulton County, Indiana reaches a depth of 35 feet. Fletcher Lake is charted here across 7 closed depth contours, from the 5 ft line down to 35 ft, enclosing about 37 acres of water. Half of that water lies inside the 25 ft line, and only 2.4 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Acreages are computed from the closed Indiana DNR Lake Bathymetry contour rings, with islands subtracted. Shares are of the 37 acres inside the outermost charted contour (the 5 ft line), which is the outer edge of the mapped water, several state files carry no 0 ft shoreline line, so this is not the same as a share of the lake's published surface area.

Fishing Fletcher Lake: steep sides for its size

Inside its outermost 5 ft contour the survey charts about 37 acres of Fletcher Lake, with the 25 ft line enclosing half of it, so the bottom holds its depth well out from the bank rather than tapering off a long shallow margin. The sharpest change on the chart is between 25 and 30 ft, where the mapped water loses 8.1 acres in 5 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. 2.4 acres, 6.5% of the mapped water, lie inside the deepest 35 ft contour, toward the middle of the lake. With 35 ft at its deepest there is no true cold-water layer here, so structure does the work the thermocline does elsewhere: fish the points and inside turns where the 25 and 30 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.

Fletcher Lake depth map FAQs

How deep is Fletcher Lake?
Fletcher Lake reaches a maximum depth of 35 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 7 closed depth contours over about 37 acres, and half of that water sits inside the 25 ft line.
Where is the deepest part of Fletcher Lake?
The deepest charted water on Fletcher Lake lies inside the 35 ft contour, toward the middle of the lake. That contour encloses 2.4 acres, 6.5% of the mapped water, so it is a small target on a small water, the depth chart above gives the contour to line up on.
How much of Fletcher Lake is shallower than 25 feet?
About half. The 25 ft contour encloses 17 acres of the roughly 37 acres inside the outer 5 ft line, so the other half of the water is shallower than 25 feet. The sharpest drop is between 25 and 30 feet, where the mapped water sheds 8.1 acres.
How accurate is this Fletcher Lake depth map?
The contours come from the Indiana DNR Lake Bathymetry survey, retrieved August 2026 and last rebuilt on August 19, 2026. Depths change over time with water levels and sediment, so treat this map as a planning guide for fishing, and never use it for navigation. Per Indiana DNR, the data are graphical representations for reference only, not a survey instrument. Acreages are computed from the published contour geometry, not from a separate area survey, so read them as close approximations.
