Sand Pond

Sand Pond was originally called Little Hancock Pond by Denmark’s early settlers. On several maps, it is also referred to as Walden Pond, named after the girl’s camp that was established on the pond in the summer of 1917. Sand Pond is adjacent to Hancock Pond and the bodies of water are actually connected via a shallow thoroughfare.

Fishing

The pond has many coves, points, and islands that provide excellent habitat for a variety of warmwater fish species, including smallmouth and largemouth bass. Yellow perch, chain pickerel and hornpout are also found within its waters. Sand Pond lacks suitable salmonid spawning habitat. Oxygen depletion in the deeper waters of the pond limits the habitat for both trout species in the summer months. The large number of competing warmwater fish species further limits the potential for coldwater fisheries management. Smelt, juvenile yellow perch, and landlocked alewives provide an exceptional forage base for the bass. Other species present are: minnows, golden shiner, common shiner, fallfish white sucker, hornpout (bullhead), banded killifish, pumpkinseed sunfish, redbreast sunfish and American eel.

Water Quality: 2019

The average Secchi disk reading for 2019 was 5.37 meters, fell into the moderately clear range, and was shallower than the long-term average of 6.12 meters. The average total phosphorus reading of 7.63 ppb fell into the moderate range and was less than the long-term average of 8.23 ppb. Deep water phosphorus values did reach into the high range. The chlorophyll-a average of 2.5 ppb fell into the moderate range and was less than the long-term average of 3.43 ppb. Long-term trend analysis indicates chlorophyll–a concentrations in Sand Pond are stable, total phosphorus concentrations are stable, and clarity readings are stable. The average color reading for 2019 was 21.50 SPU, indicating that water in Sand Pond is moderately colored. Suitable fish habitat was present from June through July, transitioned to marginal habitat in August, and became unsuitable in September.

2019 average vs. long-term average

  • Clarity: The average Secchi disk reading for 2019 was 5.37 meters, fell into the moderately clear range, and was shallower than the long-term average of 6.12 meters.
  • Chlorophyll: The chlorophyll-a average of 2.5 ppb fell into the moderate range and was less than the long-term average of 3.43 ppb.
  • Phosphorous: The average total phosphorus reading of 7.63 ppb fell into the moderate range and was less than the long-term average of 8.23 ppb.

    Hancock and Sand Ponds Watershed Project

    After a successful survey of the watershed to identify erosion sites and raise public awareness about water quality problems, LEA partnered with the Hancock and Sand Pond Association and Cumberland County Soil and Water Conservation District to correct some of the highest priority sites that were found. Through this grant, large conservation practices were installed on the West Shore Road, Wabanaki Road and Sand Pond Way. A significant portion of the grant was also used to address problems associated with residential properties.

    Watershed Soils

    19 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.

    9 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.

    49 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.

    Less than 1 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.

    8 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 15 percent of the watershed is taken up by the pond.
