Boat: 1 ramp or launch on file for this water.
Start here: Launch at Lake Bonny Public Boat Ramp, 1 lane, concrete.

The lake

Lake Bonny covers 290 acres in Florida, across Polk County. It is a lake: 95.5% of it is 10 feet deep or less; the deepest point measured is at least 14 feet (4.3 m). Our records hold 17 species for this water.

Depth and bottom

Deepest measured point: at least 14 ft (4.3 m). That is the deepest contour line: the bottom goes deeper. 95.5% of the water is 10 feet or shallower. We hold 51 depth contour lines for this water.

  • 0–2 ft: 8.1% of the water
  • 2–3 ft: 7.4% of the water
  • 3–4 ft: 9.8% of the water
  • 4–5 ft: 11.1% of the water
  • 5–6 ft: 12.7% of the water
  • 6–7 ft: 13.4% of the water
  • 7–8 ft: 11.7% of the water
  • 8–9 ft: 11.2% of the water
  • 9–10 ft: 10.1% of the water
  • 10–12 ft: 4.4% of the water

Water and conditions

Water clarity runs 1.1–2.5 feet on our readings, averaging 1.8 feet, from 82 readings. Our water temperature readings average 77°F; they do not cover the whole year, so this is not a yearly average. The coldest single reading we hold is 60°F and the warmest is 88°F; the warmest monthly average is 86°F. pH averages 8.1. These readings span 2016–2025.

1 ramp or launch on this water

On this water we hold 1 trailer ramp and 1 fishing pier.

  • Lake Bonny Public Boat Ramp — 1 lane, concrete, parking for 4 trailers (paved), no fee, dock. Lakeland, City of Lakeland. ~1635 East Main Street, Lakeland 33801 · website lakelandgov.net/departments/parks-recreation

Fishing piers

  • Lake Bonny Park — no fee. Lakeland, City of Lakeland. 800 U. S. 98, Lakeland 33801

Only one of the 2 places listed has both a fee and opening hours on file: a blank means we hold no such field, not that it is free or always open, and this list may not be complete.

What is hard here

With 95.5% of the water 10 feet or less, low level turns the flats into hazards. Only 1 public ramp is on file, so the launch decides where you fish. Alligators live in Florida fresh water. Keep clear of the bank edge at dawn and dusk, and keep pets away from it. Summer water sits at 86°F: heat and afternoon lightning are the real risks, not the fishing.

Where this data comes from

  • Florida DEP — Florida Department of Environmental Protection: depth contours: class A, a survey of the bottom.
  • EPA NLA — EPA National Lakes Assessment: class B, a depth figure measured and published by an agency, without a bottom map, 2007.
