Griffy Lake depth map
Griffy Lake in Monroe County, Indiana reaches a depth of 30 feet. Griffy Lake is charted here across 9 closed depth contours, from the 3 ft line down to 27 ft, enclosing about 97 acres of water. Half of that water lies inside the 18 ft line, and only 14 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 97 acres inside the outermost charted contour (the 3 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. The survey also records a 30 ft sounding, marked as a point rather than a closed contour, so it is not charted as a band.
Fishing Griffy Lake: steep sides for its size
Inside its outermost 3 ft contour the survey charts about 97 acres of Griffy Lake, with the 18 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 6 and 9 ft, where the mapped water loses 15 acres in 3 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. 14 acres, 14% of the mapped water, lie inside the deepest 27 ft contour, toward the northwestern corner of the lake. With 30 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 6 and 9 ft lines pinch together, hardest in early season and again as fish follow bait back down in autumn.
Griffy Lake depth map FAQs
- How deep is Griffy Lake?
- Griffy Lake reaches a maximum depth of 30 feet in the Indiana DNR Lake Bathymetry survey. Most of it is far shallower: the survey charts 9 closed depth contours over about 97 acres, and half of that water sits inside the 18 ft line. The 30 ft figure is a single recorded sounding rather than a closed contour, so the deepest line you can actually trace on the map is 27 ft.
- Where is the deepest part of Griffy Lake?
- The deepest charted water on Griffy Lake lies inside the 27 ft contour, toward the northwestern corner of the lake. That contour encloses 14 acres, 14% 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 Griffy Lake is shallower than 18 feet?
- About half. The 18 ft contour encloses 41 acres of the roughly 97 acres inside the outer 3 ft line, so the other half of the water is shallower than 18 feet. The sharpest drop is between 6 and 9 feet, where the mapped water sheds 15 acres.
- How accurate is this Griffy 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.
