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. -

Page 10 Summer 2014 Free LEA Lake News The Maine Lake Science Center – Now a Reality by Peter Lowell LEA Board Votes to Buy the Science Center Property As kids growing up on Highland Lake, we never saw algae clouds that look like green cotton candy. The sand and gravel of the lake bottom was always clean and the rocks were clear of sediment. Unfortunately, these simple indicators of water quality decline are now widespread. Our work over 43 years has led us to conclude that Maine lakes are degrading because of continued watershed development and decline is being accelerated by climate change. All of our lakes have changed over the past few decades, and their future is certainly in doubt. For six years, LEA has studied the status of lake science and visiting lake centers around the country to learn their methods and establish relationships. LEA conducts more lake testing than anyone in Maine, and we feel that no one adequately understands the “tipping points” that lead to a decline in water quality. -

VOLUME II. AUGUSTA: SPRAGUE & SON, PRINTERS TO THE STATE. 188 4. REPORT OF THH Railroad Commissioners OF THE STATE OF MAINE. 1883. --·--- AUGUSTA: SPRAGUE & SON, PRINTERS TO THE STATE. 18 84. • * • REPORT. 1'0 the Governor of Maine: The Railroad Commissioners respectfully submit their twenty-fifth annual report. The importance of the railroad system of Maine, as a means of developing the resources of the State, is becoming more apparent every year. By reason of the facilities it affords, mineral wealth is being uncovered, manufacturers are utiliz ing the abundant water powers, and our products are afforded ready markets; and, although in ·obtaining these facilities in some localities, heavy burdens have been assumed by cities and towns, still we think the benefit derived will fully com pensate them in the end. We do not, however, wish to be understood as favoring the principle of towns and cities aiding in the construction of railroads. The benefit to be derived by a large portion of the inhabitants of a town, is too remote to justify it in most instances. We again have the pleasure of congratulating the public, and the several railroad corporations operating roads in the State, on the remarkable exemption from any serious casualties during the year. -
Water and Natural Resources
Water and Natural Resources State Goal: Water Resources: To protect the quality and manage the quantity of the State’s water resources, including lakes, aquifers, great ponds, estuaries, rivers, and coastal areas Natural Resources: To protect the State’s other critical natural resources, including without limitation, wetlands, wildlife and fisheries habitat, sand dunes, shorelands, scenic vistas, and unique natural areas. Introduction: This chapter provides a comprehensive inventory of Windham’s natural and water resources. Understanding these systems and assets is essential to encouraging both environmentally and economically sustainable land use decisions that insure the enjoyment and protection of these resources for future generations. Watersheds A watershed is defined generally as an area that drains into a waterway, such as a stream, river, surface water body or aquifer, and is delineated by both natural and man-made features. Watersheds are interconnected such that action taken in one part of a system can affect water quality further downstream in that system. All of Windham lies within the Casco Bay Watershed, which includes 945 miles and about a quarter of a million people. The town is also comprised of many smaller sub-watersheds associated with its lakes, ponds, wetlands, streams, and rivers. Some of these are located wholly within municipal boundaries and some are shared with neighboring communities. Windham also lies partially within the Sebago lake watershed, comprised of approximately 300,000 acres (450 square miles) across 23 towns. Sebago Lake is the public water supply for 11 towns within the Greater Portland area including Windham. A map displaying Windham’s watersheds and wetland systems is located below. -
Maine Lakes Report 2012
Maine Lakes Report 2012 Dear Friends of Maine Lakes, This report on the health of Maine lakes reflects the effort of more than 1,000 volunteer citizen scientists who monitored several hundred lake basins throughout the State in 2012. Many of them have been doing so continuously for decades, and a few have been involved for most of the 42 years since the Maine Legislature officially authorized volunteer lake monitoring. Their work is a strong testimony to the level of public commitment in Maine to our clear, clean lakes, and it is probably not coincidental that our lakes have remained as healthy as they have under the watch of these individuals. The Maine Volunteer Lake Monitoring Program (VLMP) is believed to be the longest-standing statewide citizen lake monitoring program in America, having been formed at about the time of the passage of the historic Federal Clean Water Act. The Mission of the Maine Volunteer Lake Monitoring Program is to help protect Maine lakes through widespread citizen participation in the gathering and dissemination of credible scientific information pertaining to lake health. The VLMP trains, certifies and provides technical support to hundreds of volunteers who monitor a wide range of indicators of water quality, assess watershed health and function, and screen lakes for invasive aquatic plants and animals. In addition to being the primary source of lake data in the State of Maine, VLMP volunteers benefit their local lakes by playing key stewardship and leadership roles in their communities. Our primary partners are the Maine Department of Environmental Protection (DEP) and the US Environmental Protection Agency, which provide a wide range of financial, technical and management support to the program. -

Page 10 Winter 2016 Free LEA Lake News Success on the Songo River and Brandy Pond! By Christian Oren After eleven summers of hard work, LEA is declaring victory in the battle against milfoil in the Songo River and Brandy Pond. When the project was first begun, huge patches of milfoil as big as football fields choked the entire length of the Songo. Now, boaters can pass through the river without ever seeing a single stalck of the plant. Never before has such a large and extensive invasive aquatic plant infestation been brought under control in the history of the State of Maine. The dozen or so infestations in Brandy Pond were also persistent, but seem to have been quelled by years of repeated harvesting. We declared victory on the Songo for two main reasons. First, the density of milfoil on the entire length of the river was much lower than we had seen in previous years. Even at the height of the growing season, there was only one plant for every 100 feet of shoreline, or less. -

Cumulative Impacts to Environmental Conditions on the Presumpscot River and Its Shorelands
Cumulative Impacts to Environmental Conditions on the Presumpscot River and its Shorelands (DRAFT -- As distributed at the June 2002 Public Meetings) Title Page pictures Deleted due to large memory size. See separate file Prepared by the Presumpscot River Plan Steering Committee With Technical Assistance Provided by Land and Water Associates Hallowell, Maine And Funding and Assistance Provided by Casco Bay Estuary Project June 11, 2002 ADDENDUM April 18, 2003 Note on the Scope of Analysis for this Cumulative Impacts Report: The geographic scope of this analysis of cumulative impacts is the Presumpscot River from its outlet at Sebago Lake, including its tributaries and adjacent corridor lands, to and including the Casco Bay Estuary. This report addresses the impacts of the regulation of flows out of Sebago Lake at the Eel Weir Dam on the river and Casco Bay Estuary, since the flow regime on the river is almost entirely controlled by management of the Eel Weir Dam, and the Presumpscot River is the largest source of freshwater to Casco Bay. However, it does not include or address issues related to Sebago Lake levels. Comments received at the June 2002 public information meetings raised concerns about the impacts of flow regulation at the Eel Weir Dam on Sebago lake shorelands and wetlands. While it is acknowledged that the regulation of flows at the Eel Weir Dam has impacts not only on the river and estuary but also on Sebago Lake, these impacts are not addressed in this report, and there are no recommendations included in the report to change operations at the Eel Weir Dam. -
