Providing public access to these bodies of water is extremely impor- tant to us because we want both residents and visitors alike to enjoy them to the fullest. The Department of Inland Fisheries and Wildlife works diligently to provide access to Maine’s waters, whether it’s a remote mountain pond, or Maine’s Casco Bay. How you conduct yourself on Maine’s waters will go a long way in de- termining whether new access points can be obtained since only a fraction of our waters have dedicated public access.

  • Sebasticook Lake
    SEBASTICOOK LAKE TOTAL MAXIMUM DAILY (ANNUAL) LOAD Final Report DEPLW 2000 - 110 Maine Department of Environmental Protection 8 February 2001 Maine Lake TMDLs - What, Why, Where, and When? You are no doubt wondering what the acronym 'TMDL' represents and what it is all about. TMDL is actually short for 'Total Maximum Daily Load.' This acknowledgment probably does little to clarify TMDLs in most people's minds. However, replace 'daily' with 'annual' and insert 'phosphorus' before 'load' and it may begin to make more sense to more people. Simply stated, excess nutrients (such as phosphorus) in lakes promote nuisance algae growth/blooms - resulting in the violation of water quality standards. A TMDL is prepared to estimate the total amount of dissolved phosphorus that a lake can accept (annually) without harming water quality. Historically, development of TMDLs was first mandated by the Clean Water Act in 1972 - and was applied primarily to point sources of water pollution. As a result of public pressure to further clean-up water bodies - lake and stream TMDLs are now being prepared for Non-Point Sources (NPS) of water pollution. Nutrient enrichment of lakes through excess total phosphorus originating from watershed soil erosion has been generally recognized as the primary source of NPS pollution. Major land use activities contributing to the phosphorus load in lakes include residential-commercial developments, agriculture, roadways, and commercial forestry. Statewide, there are approximately 35 lakes which do not meet water quality standards due to excessive amounts of total phosphorus. The first Maine lake TMDL was developed (1995) for Cobbossee Lake by the Cobbossee Watershed District (CWD) - under contract with ME-DEP and US-EPA.

  • China Lake Characterisitcs
    CHINA LAKE CHARACTERISITCS WATERSHED DESCRIPTION The China Lake watershed is located in Kennebec County, Maine, and is situated within the townships of China, Vassalboro, and Albion (Figure 8). The lake is classified by the Maine Information Display Analysis System (MIDAS) as MIDAS #5448 (PEARL 2005a). This classification system assigns unique four-digit codes to identify all lakes and ponds in Maine. China Lake is located 44.25° N and 69.33° W, at an elevation of 59.1 m (194 ft), and covers a surface area of 1,604 ha (3,963 acres) (PEARL 2005a). China is classified geographically as a two basin lake, with an East Basin and West Basin (PEARL 2005a). Bathymetrically, China Lake is described as a three basin lake, with three deep holes forming the western, southeastern, and northeastern basins (Manthey, pers. comm.). China Lake has an average depth of 10.1 m (33.1 ft), a maximum depth of 28.2 m (92.4 ft), and a volume of 120,001,704 m3 (97,286.4 acre- ft) (PEARL 2005a). The water within China Lake flows from input to output at an annual rate of 0.35 flushes per year. There are several small islands within China Lake, most notably Indian Island, Green Island, Bradley Island, and Moody Island. China Lake is dimictic, experiencing thermal stratification in the summer with turnovers occurring each spring and fall. Algal blooms have been reported yearly since 1983 and the Maine Department of Environmental Protection (MDEP) currently describes China Lake as a “frequently blooming” lake. This classification means that the lake commonly experiences late summer and early fall reductions in water transparency due to algal blooms (MDEP 2005a).
