Peabody Pond, located in the towns of Sebago, Naples and Bridgton, was named for Captain John Peabody, one of the first settlers in the South Bridgton area. Peabody is shaped like a wide “V” pointed toward the northwest. Paddle the complete shoreline, and you’d cover about six miles. The pond is encircled by low ridges and mountains.
Peabody Pond is well suited for both warmwater and coldwater fish. Its rocky shorelines and protected coves provide good habitat for bass, yellow perch and chain pickerel. The deep chasm that runs through the center of the pond stays cool during the summer months, giving landlocked salmon, brook trout and lake trout refuge from the warmer waters above. Dissolved oxygen depletion does limit some of this habitat in late summer. The Northwest River, which is the outlet for Peabody Pond, also is a good spawning ground for wild landlocked salmon. Other fish in the pond include hornpout, rainbow smelt, white sucker, fallfish, common shiner, pearl dace, banded killifish and pumpkinseed sunfish.
The average Secchi disk reading for 2020 was 7.67 meters, fell into the high clarity range, and was deeper than the long-term average of 7.42 meters. The average total phosphorus reading of 5.00 ppb stayed within the moderate range and was less than the long-term average of 5.68 ppb. The average deep water phosphorus value was not significantly above surface water phosphorus values, which suggests phosphors recycling is not problematic. The chlorophyll-a average of 2.63 ppb fell into the moderate range and was less than the long-term average of 2.67 ppb. Long-term trend analysis indicates chlorophyll–a concentrations in Peabody Pond are stable, total phosphorus concentrations are stable, and clarity readings are increasing. The average color reading for 2020 was 13.38 SPU, indicating that water in Peabody Pond is moderately colored. Suitable coldwater fish habitat was present from June through August and became marginal in September.

The line represents the long-term average value and the dot represents 2020’s average value. The small red dots represent individual readings taken in 2020.
28 percent of soils in the watershed are type A soils. Type A soils tend to be well drained sands, loams, and gravels. When vegetation is removed and the soil is exposed they can be susceptible to erosion. Because they are often coarse with ample pore space, there is low runoff potential and water will not usually pool on them. These soils can be good places to site leach fields or infiltrate stormwater from a home or residence.
3 percent of soils in the watershed are type B soils. B soils have moderate infiltration rates and fine to moderate texture and soil size. They are usually made up silts and loams. Although not as well drained as A soils, they can also be good places to site leach fields and infiltrate stormwater.
34 percent of soils in the watershed are type C soils. C soils have low infiltration rates and typically have a layer that impedes the movement of water. These soils are made of sands, clays, and loams and are one of the most common soil types in western Maine.
6 percent of soils in the watershed are type D soils. D soils have a high runoff potential and very low infiltration rates. Soils with a high water table, clay or other impervious layer near the surface are typically D soils. These soils are often associated with wetlands.
7 percent of soils in the watershed are type C/D soils. C/D soils are a mix of these two soil types. They have fairly high runoff potential and low infiltration rates and often pool water.
The remaining 23 percent of the watershed is taken up by the pond.
