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. -
Fishery Interim Summary Report Series No. 08-04: Rapid River Fishery Management
FISHERY INTERIM SUMMARY REPORT SERIES NO. 08-04 RAPID RIVER FISHERY MANAGEMENT By David P. Boucher Maine Department of Inland Fisheries and Wildlife Division of Fisheries and Hatcheries Augusta, Maine December 2008 Job F-014 Interim Summary Report No. 4 (2007) Rapid River Fishery Management SUMMARY The Rapid River, located in Township C and Upton in Oxford County, has long been noted for its outstanding brook trout population. Brook trout in the Rapid River are sustained entirely by natural reproduction and support a popular, heavily utilized sport fishery of regional and statewide significance. Landlocked salmon are also present and provide an important ancillary fishery. During the 1980's, smallmouth bass were illegally introduced into Umbagog Lake, where they became well established and have since migrated to the Rapid River. A clerk creel survey was conducted in 2007 to monitor angler use, catch, and harvest subsequent to changes in fishing regulations and flow regimes, and to monitor the impacts of smallmouth bass. Creel survey data suggested that a decline in brook trout production documented earlier (from 2002 to 2004) was at least partially arrested, and that the vigorous expansion of smallmouth bass numbers slowed or declined by 2007. It's likely that increasingly restrictive fishing regulations, beginning in 2004, were partially responsible for the positive trend. Three consecutive years of unfavorable flows for bass spawning (2005- 2007), and the wet, cool conditions that prevailed during those years, were also important factors. By manipulating flows from Middle Dam, we'll maintain a high level of stress to smallmouth bass during their spawning, incubation, and early recruitment periods, and therefore maintain or improve conditions for trout survival. -
Concord River Diadromous Fish Restoration FEASIBILITY STUDY
Concord River Diadromous Fish Restoration FEASIBILITY STUDY Concord River, Massachusetts Talbot Mills Dam Centennial Falls Dam Middlesex Falls DRAFT REPORT FEBRUARY 2016 Prepared for: In partnership with: Prepared by: This page intentionally left blank. Executive Summary Concord River Diadromous Fish Restoration FEASIBILITY STUDY – DRAFT REPORT EXECUTIVE SUMMARY Project Purpose The purpose of this project is to evaluate the feasibility of restoring populations of diadromous fish to the Concord, Sudbury, and Assabet Rivers, collectively known as the SuAsCo Watershed. The primary impediment to fish passage in the Concord River is the Talbot Mills Dam in Billerica, Massachusetts. Prior to reaching the dam, fish must first navigate potential obstacles at the Essex Dam (an active hydro dam with a fish elevator and an eel ladder) on the Merrimack River in Lawrence, Middlesex Falls (a natural bedrock falls and remnants of a breached dam) on the Concord River in Lowell, and Centennial Falls Dam (a hydropower dam with a fish ladder), also on the Concord River in Lowell. Blueback herring Alewife American shad American eel Sea lamprey Species targeted for restoration include both species of river herring (blueback herring and alewife), American shad, American eel, and sea lamprey, all of which are diadromous fish that depend upon passage between marine and freshwater habitats to complete their life cycle. Reasons The impact of diadromous fish species extends for pursuing fish passage restoration in the far beyond the scope of a single restoration Concord River watershed include the importance and historical presence of the project, as they have a broad migratory range target species, the connectivity of and along the Atlantic coast and benefit commercial significant potential habitat within the and recreational fisheries of other species. -

The Dirty History of Portland Harbor
Reprinted from a 1994 publication The Dirty History of Portland Harbor hen scientists began looking closely at the sediments and at W the bottom of Casco Bay beginning in the early 1980s, they confronted a pollution puzzle. Sediments taken from various locations throughout the Bay, and especially in Portland Harbor, held a wide variety of potentially toxic chemicals. Until we know more about how these heavy metals, pesticides and other compounds affect marine life, it’s hard to know what lasting impact the pollution in Casco Bay may have. But it was decided that the more we know about where those pollutants came from, the better chances we will have in preventing future problems. The Casco Bay Estuary Project (now Casco Bay Early industry was limited by natural energy sources, like this tidal mill at Estuary Partnership) commissioned environmental Stroudwater. (courtesy: Sullivan Train & Photo) historian Edward Hawes to do some detective work, hoping that he could turn up some puzzle pieces from the Casco Bay. Lead, cadmium and mercury concentrations were watersheds that feed the Bay. The industrial legacy he found comparatively high in Back Cove, as were lead and mercury was a surprise to almost anyone who thinks they know the in the inner Fore River. Lead was also relatively high in the Portland area. Presumpscot River estuary. Additional metals — nickel, silver, arsenic, chromium A Pollution Problem and zinc — were evident in lesser concentrations. This widespread contamination was a little mystifying. In this age hen investigators began sampling Casco Bay’s of environmental regulation, how could so much pollution sediments in the 1980s, levels of pollution have landed in the Bay? W were found that merited additional attention. -

FISHERY INTERIM SUMMARY REPORT SERIES NO. 11-03 RAPID RIVER FISHERY MANAGEMENT By David P. Boucher Maine Department of Inland Fisheries and Wildlife Division of Fisheries and Hatcheries Augusta, Maine December 2011 Job F-014 Interim Summary Report No. 5 (2008-2010) Rapid River Fishery Management SUMMARY The Rapid River, located in Township C and Upton in Oxford County, has long been noted for its outstanding brook trout population. Brook trout in the Rapid River are sustained entirely by natural reproduction and support a popular, heavily utilized sport fishery of regional and statewide significance. Landlocked salmon are present also and they provide an important ancillary fishery. During the 1980’s, smallmouth bass were illegally introduced into Umbagog Lake, where they became well established and have since migrated to the Rapid River.

The most recent creel surveys, including in 2010, were intended to monitor angler use, catch, and harvest subsequent to changes in fishing regulations and flow regimes, and to assess the impacts of smallmouth bass on the river’s brook trout and salmon fisheries. Creel survey data suggested that a decline in brook trout production documented earlier (from 2002 to 2004) was at least partially arrested, and that the vigorous expansion of smallmouth bass numbers slowed or declined. We attributed this to improved protection of brook trout provided by more restrictive fishing regulations, beginning in 2004; to wet, cool environmental conditions that prevailed during several years from 2005 to 2010; and to unfavorable river flows for bass spawning and early recruitment during the same period. -
Hiking/Nature Trails
HIKING/NATURE TRAILS LEVEL TRAIL NAME ANGEL FALLS: 90 foot plunge; one of Maine's tallest waterfalls! From Oquossoc, take Rt. 17 south for about 18.5 miles. Turn right onto an unnamed gravel road (adjacent to a large open field). Immediately cross a bridge over the Swift River, then turn right onto Bemis Road and drive north for about 3.5 miles. Look for a road on the left going downhill and follow it into an old gravel pit (large boulder with graffiti), and park. Look for red blazes, and follow a logging path across Berdeen Stream, and continue following the trail (red blazed) to Mountain Brook. The trail follows the brook up stream and crosses (rock hops) the brook three times before you come to the falls. APPALACHIAN TRAIL: Trail runs from Andover through our area beyond Saddleback Mountain. To reach Trail on Rt. 17, travel 11.1 miles south from Oquossoc. Trail from Rt. 17 to Rt. 4 is approximately 13 miles. It is moderate hiking, no real steep sections. Four miles from Rt. 17 is Sabbath Day Pond and shelter. To reach trail-crossing Rt. 4, travel south approximately 9 miles from the center of Rangeley. From Rt. 4 to top of Saddleback Mountain it is 5 miles. The last mile is above tree line. Please stay on marked trail, as this is a fragile alpine area. Also on this trail, you will find Piazza Rock, shelter and tent sites 1.3 miles from Rt. 4. There is a side trail off of Saddleback Mountain, which then follows ski trails to base lodge approx. -
