How deep is Frash Pond?

Frash Pond reaches a maximum depth of 40 feet in the CT DEEP Lake Bathymetry survey. Most of it is far shallower: the survey charts 9 closed depth contours over about 27 acres, and half of that water sits inside the 20 ft line.

Where is the deepest part of Frash Pond?

The deepest charted water on Frash Pond lies inside the 40 ft contour, toward the eastern side of the lake. That contour encloses 2.7 acres, 10% 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 Frash Pond is shallower than 20 feet?

About half. The 20 ft contour encloses 12 acres of the roughly 27 acres inside the outer 0 ft line, so the other half of the water is shallower than 20 feet. The sharpest drop is between 0 and 5 feet, where the mapped water sheds 5 acres.

How accurate is this Frash Pond depth map?

The contours come from the CT DEEP 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. Acreages are computed from the published contour geometry, not from a separate area survey, so read them as close approximations.

Frash Pond depth map

Frash Pond in Stratford, Connecticut reaches a depth of 40 feet. Frash Pond is charted here across 9 closed depth contours, from the 0 ft line down to 40 ft, enclosing about 27 acres of water. Half of that water lies inside the 20 ft line, and only 2.7 acres lie inside the deepest one. Every contour is on the interactive map below, free and without an account.

Frash Pond depth chart data: water enclosed by each contour
Depth contour	Water inside it	Share of mapped water
0 ft	27 acres	100%
5 ft	22 acres	80%
10 ft	20 acres	72%
15 ft	15 acres	56%
20 ft	12 acres	44%
25 ft	9.4 acres	34%
30 ft	7.6 acres	28%
35 ft	5 acres	18%
40 ft	2.7 acres	10%

Acreages are computed from the closed CT DEEP Lake Bathymetry contour rings, with islands subtracted. Shares are of the 27 acres inside the outermost charted contour (the 0 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 Frash Pond: an evenly graded bottom

Inside its outermost 0 ft contour the survey charts about 27 acres of Frash Pond, with the 20 ft line enclosing half of it, so the bottom loses depth gradually and evenly, with no broad shelf and no single abrupt drop. The sharpest change on the chart is between 0 and 5 ft, where the mapped water loses 5 acres in 5 ft of depth, that band is the contour to work first, because it is where the bottom stops being flat. The deepest 40 ft contour holds 2.7 acres, 10% of the mapped water, toward the eastern side of the lake. Nothing here reaches a true cold-water layer at 40 ft, so structure does the thermocline's work: the points and inside turns where the 0 and 5 ft lines pinch together fish hardest in early season, and again as fish follow bait back down in autumn.

Ice fishing on Frash Pond

At 40 ft, Frash Pond is a workable ice depth: deep enough to hold fish all winter without the slow freeze-up of a big basin. Start on the 40 ft hole, 2.7 acres of it, at first light, then move up onto the 0–5 ft break as the sun gets up, and fish the flats inside the 20 ft line through the middle of the day. Check ice thickness locally before you walk out.
