Geologic Site of the Month: Why Is Sebago Lake So Deep?
Why is Sebago Lake so deep? Maine Geological Survey Maine Geologic Facts and Localities February, 1999 Why is Sebago Lake so deep? 43° 51‘ 13.36“ N, 70° 33‘ 43.98“ W Text by Robert A. Johnston Maine Geological Survey, Department of Agriculture, Conservation & Forestry 1 Why is Sebago Lake so deep? Maine Geological Survey Introduction Modern geophysical equipment allows geologists to investigate previously unmapped environments, including ocean and lake floors. Recent geophysical research studied the types, composition, areal extent, and thickness of sediments on the bottom of Sebago Lake in southwestern Maine. Geologists used side- scan sonar and seismic reflection profiling to map the bottom of the lake. Approximately 58 percent of the lake bottom was imaged with side-scan sonar and over 60 miles of seismic reflection profiles were collected. This web site will discuss the findings of the seismic reflection profiling. Maine Geological Survey, Department of Agriculture, Conservation & Forestry 2 Why is Sebago Lake so deep? Maine Geological Survey Physiographic setting Sebago Lake, although second in surface area to Moosehead Lake, is Maine's deepest lake. With a water depth of 316 feet, its deepest part is 49 feet below sea level! Sebago Lake is located in southwestern Maine 20 miles northwest of Portland and 50 miles southeast of the White Mountains. It lies along the transition between the Central Highlands and the Coastal Lowlands physiographic regions of New England (Figure 1). The abrupt change in landscape can be seen in panoramic views from several vantage points near Sebago Lake. Denny, 1982 Denny, Maine Geological Survey From From Figure 1. -
Considerations for Rezoning on Lakes
STATE OF MAINE DEPARTMENT OF AGRICULTURE, CONSERVATION & FORESTRY LAND USE PLANNING COMMISSION 22 STATE HOUSE STATION WALTER E. WHITCOMB PAUL R. LEPAGE AUGUSTA, MAINE 04333-0022 COMMISSIONER GOVERNOR NICHOLAS D. LIVESAY EXECUTIVE DIRECTOR Memorandum To: LUPC Commissioners From: Samantha Horn, Planning Manager Ben Godsoe, Senior Planner Date: October 5, 2018 Re: Considerations for Rezoning Near Lakes, Staff Analysis Lake resources are important to Maine’s character, environment and economy. Healthy lakes are a strong draw for local residents and visitors alike, and play a critical role in sustaining fish and wildlife populations. When the Commission considers the location of future subdivisions, it is important to be deliberate about which lakes may be near new zones for subdivisions. The May 2018 draft of rule revisions for adjacency included a proposal that any new zones for waterfront subdivision should be either 1) on a lake or pond that is within a certain distance of services (i.e., within primary or secondary locations); or 2) on a lake or pond that is already developed. Outside of primary or secondary locations, lakes under the proposed revisions that could be eligible for rezoning include management class 3, 4, and 5 lakes, as well as certain class 7 lakes. During the public hearing on the draft rule revisions, commenters raised concerns that there was not sufficient information available to tell which or how many class 7 lakes qualify as having sufficient development to make them potentially be eligible for rezoning. Without this information, commenters raised concerns that a large number of lakes could possibly be “open for development.” Commenters requested more information on which class 7 lakes could be affected by the proposal. -

Official List of Public Waters
Official List of Public Waters New Hampshire Department of Environmental Services Water Division Dam Bureau 29 Hazen Drive PO Box 95 Concord, NH 03302-0095 (603) 271-3406 https://www.des.nh.gov NH Official List of Public Waters Revision Date October 9, 2020 Robert R. Scott, Commissioner Thomas E. O’Donovan, Division Director OFFICIAL LIST OF PUBLIC WATERS Published Pursuant to RSA 271:20 II (effective June 26, 1990) IMPORTANT NOTE: Do not use this list for determining water bodies that are subject to the Comprehensive Shoreland Protection Act (CSPA). The CSPA list is available on the NHDES website. Public waters in New Hampshire are prescribed by common law as great ponds (natural waterbodies of 10 acres or more in size), public rivers and streams, and tidal waters. These common law public waters are held by the State in trust for the people of New Hampshire. The State holds the land underlying great ponds and tidal waters (including tidal rivers) in trust for the people of New Hampshire. Generally, but with some exceptions, private property owners hold title to the land underlying freshwater rivers and streams, and the State has an easement over this land for public purposes. Several New Hampshire statutes further define public waters as including artificial impoundments 10 acres or more in size, solely for the purpose of applying specific statutes. Most artificial impoundments were created by the construction of a dam, but some were created by actions such as dredging or as a result of urbanization (usually due to the effect of road crossings obstructing flow and increased runoff from the surrounding area). -

Partnership Opportunities for Lake-Friendly Living Service Providers NH LAKES Lakesmart Program
Partnership Opportunities for Lake-Friendly Living Service Providers NH LAKES LakeSmart Program Only with YOUR help will New Hampshire’s lakes remain clean and healthy, now and in the future. The health of our lakes, and our enjoyment of these irreplaceable natural resources, is at risk. Polluted runoff water from the landscape is washing into our lakes, causing toxic algal blooms that make swimming in lakes unsafe. Failing septic systems and animal waste washed off the land are contributing bacteria to our lakes that can make people and pets who swim in the water sick. Toxic products used in the home, on lawns, and on roadways and driveways are also reaching our lakes, poisoning the water in some areas to the point where fish and other aquatic life cannot survive. NH LAKES has found that most property owners don’t know how their actions affect the health of lakes. We’ve also found that property owners want to do the right thing to help keep the lakes they enjoy clean and healthy and that they often need help of professional service providers like YOU! What is LakeSmart? The LakeSmart program is an education, evaluation, and recognition program that inspires property owners to live in a lake- friendly way, keeping our lakes clean and healthy. The program is free, voluntary, and non-regulatory. Through a confidential evaluation process, property owners receive tailored recommendations about how to implement lake-friendly living practices year-round in their home, on their property, and along and on the lake. Property owners have access to a directory of lake- friendly living service providers to help them adopt lake-friendly living practices. -
