Otter Pond

Otter Pond is located just south of the Town of Bridgton. The pond is lightly developed with camps, despite its proximity to town and the seasonal popularity of this area. It is interesting to note that the pond has two outlets, one at each end, which both drain into Long Lake.

Fishing

This relatively shallow pond is homothermous with a fair amount of weedy habitat, which makes it best suited for warmwater fish management. Fisheries biologists at the Maine Department of Inland Fisheries and Wildlife introduced largemouth bass in 1958 and 1959 to enhance angling opportunities. The bass population is now self-sustaining and provides good fishing. Chain pickerel are also abundant and provide additional angling excitement.

Water Quality: 2019

Otter Pond is sampled by LEA once per year in August. The long-term average reflects data from 1988 to 2019. The Secchi disk reading for 2019 was 4.10 meters, fell into the moderate clarity range, and was not significantly different than the long-term average of 3.54 meters. The total phosphorus reading of 8.00 ppb fell into the moderate range and was not significantly different than the long-term average of 12.51 ppb. The chlorophyll-a reading of 2.00 ppb fell into the low range and was not significantly different than the long-term average of 4.57 ppb. The color reading for 2019 was 46 SPU, indicating that water in Otter Pond is highly colored.

2019 average vs. long-term average

  • Clarity: The Secchi disk (clarity) reading for 2019 was 4.10 meters, fell into the moderate clarity range, and was not significantly different than the long-term average of 3.54 meters.
  • Chlorophyll: The chlorophyll-a reading of 2.00 ppb fell into the low range and was not significantly different than the long-term average of 4.57 ppb.
  • Phosphorous: The total phosphorus reading of 8.00 ppb fell into the moderate range and was not significantly different than the long-term average of 12.51 ppb.

    Watershed Soils

    9 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.

    A trace percentage 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.

    66 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.

    14 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.

    2 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 10 percent of the watershed is taken up by the pond.
