WATER QUALITY SUMMARY

BAY OF NAPLES (BRANDY POND), NAPLES

MIDAS: 9685, Sample Station # 1

The Maine Department of Environmental Protection (ME-DEP) and the Volunteer Lake Monitoring Program (VLMP) have collaborated in the collection of lake data to evaluate water quality, track algal blooms, and determine water quality trends. This dataset does not include data for bacteria, mercury, or nutrients other than phosphorus.

Water quality monitoring datasets have been collected from Bay of Naples since 1976. During this period, 25 years of basic chemical information was collected in addition to Secchi Disk Transparencies (SDT). In summary, the water quality of Bay of Naples is considered above average based on measures of SDT, total phosphorus (TP), and Chlorophyll-a (Chla). The potential for nuisance algal blooms on Bay of Naples is low.

Water Quality Measures: Bay of Naples is a non-colored lake (average color 15 SPU) with an average SDT of 6.5 m (21.5 ft). The range of water column TP for Bay of Naples is 5 - 10 parts per billion (ppb) with an average of 7 ppb. Chla ranges from 0.9 - 6.0 ppb with an average of 2.4 ppb. Recent dissolved oxygen (DO) profiles show moderate DO depletion in deep areas of the lake. The potential for phosphorus to leave the bottom sediments and become available to algae in the water column (internal loading) is low.

Bay of Naples is sampled in conjunction with the Lakes Environmental Association (LEA) located in Bridgton, Maine.
