Title: Presumpscot River Stakeholders Plan:


1
Presumpscot River Stakeholders Plan The Future
of a Changing River Prepared by The Presumpscot
River Plan Steering Committee With Funding and
Assistance from Casco Bay Estuary Project and
EPA Region 1

Intro Background
  • Casco Bay Estuary Project for Presumpscott River
    initiated in the Spring of 2000
  • Largest freshwater resource to Casco Bay
  • Presumpscot was the site of Maines first pulp
    mill, first hydroelectric project, only
    significant canal and largest gunpowder mill, no
    other river in Maine has had virtually all its
    hydraulic head captured behind dams
  • Impact from dams on fisheries has been a concern
    since the 1700s, by 1950s the condition of the
    river reached its all time low, treatment plants
    reduced pollutant discharges following Clean
    Water Act but non-point sources of pollution
    increased
  • Interest started in 1992 when Maine Department of
    Inland Fisheries successfully reestablished a
    trout and salmon fishery just below Sebago Lake
    and after plans for the removal of Smelt Hill Dam
    and improvements in water quality from cessation
    of SAPPI Fine Papers pulp mill. Development
    pressure increased after removal of the pulp mill
    since the stench and unattractiveness of living
    near a pulp mill was also removed.
  • Originates at Sebago Lake Maines second largest
    lake, supplies greater Portland area with water,
    originally the river was a rushing river with
    many falls and rapids, abundant fish life, now it
    is slow moving and does not support as much
    wildlife
  • Focus on Presumpscot River and adjacent river
    corridor lands and some tributaries, does not
    address Sebago Lake levels

Problems
  • Clearing of land and draining or filling wetlands
    for agriculture 16 of the land is farmland
  • Timber harvesting for fuel wood, lumber,
    shipbuilding, pulp and paper
  • Extraction of sand and gravel
  • Development of settlements
  • Construction of roads, canals, railroads
  • Industrial development, dams for power
  • Use by industries and municipitalities for waste
    disposal

6
Impacts to Water Resources
  • 8 dams fragmented habitat, fast flowing water
    converted to impoundments, anadromous fish
    blocked
  • 5 waste water discharges reduce water quality
  • 31 of lower watershed is now developed
  • 16 of lower watershed is agricultural
  • Flow regimes altered

7
Changes in Water Quality
  • Basin was originally forested, original water
    quality was very similar to Sebago Lake, its
    source
  • In 2001, Portland Water Districts draft of the
    Lake report noted that Lake Sebago has
    outstanding water quality
  • Impacts of waste discharges, watershed
    development, and damming include
  • Increased TSS, increased dissolved solids,
    lowered DO, increased bacteria levels, shift to
    pollution-tolerant organisms, elevated
    temperature
  • Below Westbrook, 60 chance of meeting Class B
    for WQS for aquatic life

8
Changes in Aquatic Habitat
  • Increased temperature from development and
    slowing of water, switch from native cold water
    species (trout) to warm non-native species (bass)
  • Sedimentation aquatic community shifts to
    organisms more tolerant of turbid water, overall
    abundance of organisms decreases

9
Put and take salmon and trout fishery
The rest is only suitable for bass and panfish
10
Also impacts on wetlands, terrestrial resources,
endangered species and estuarine habitat
  • Reduction in diversity and productivity or
    floodplain from less frequent flooding
  • Loss of wetlands from draining
  • Fragmentation of wildlife travel corridors,
    reduction of wildlife populations
  • Loss of habitat for endangered species

11
The Steering Committee
  • Presumpscot River Management Plan Steering
    Committee composed of federal, state, and local
    government agencies, businesses, conservation
    organizations and other interested groups
  • Goal to work cooperatively to develop a plan
    for the future of the river, and to develop
    recommendations that work for all interests
  • Purposes
  • 1. to develop a comprehensive and unified plan
    with management objectives to guide future
    actions and decision that impact the river
  • 2. to identify opportunities for supporting
    continued improvements to the health of the river
    and its tributaries, and for capitalizing in the
    potential of a healthy river ecosystem for
    providing a diversity if public benefits,
    including recreational, educational and economic
    benefits in balance with the benefits of
    renewable hydropower energy

12
Focus Areas
  • Cumulative Impacts to the River
  • Fisheries Conditions and Opportunities
  • Open Space Conditions and Opportunities
  • Steering Committee worked for 2 years to develop
    information and proposed objectives for these
    focus areas

Protecting and Enhancing Open Space Along the
Presumpscot River
  • Open space is what Maine has going for it!
    Important to the Maine way of life.
  • Presumpscot is in a part of Maine that is losing
    open space at a rapid rate
  • Protecting open space is critical for
  • Fish and aquatic life. Riparian open space
    filter runoff from the land, protects waters from
    sedimentation, maintains cool water temperatures,
    and contributes organic matter to the aquatic
    food base
  • Wildlife Riparian open space provides habitat
    used by 80 of Maines terrestrial vertebrate
    species at some time during their lifestyle

25
Wildlife and Fish Habitat Values
  • Well vegetated open space corridors along river
    or stream have special value as wildlife habitat
  • A unique edge habitat
  • Importance to aquatic habitats
  • Importance to birds
  • Dear yards
  • 80 if Maines terrestrial vertebrate wildlife
    species use riparian areas to meet their habitat
    needs at some point in their life
  • Coalition of planning and conservation
    organizations Maine Audobon Society, Maine
    Department of Conservation, Maine Department of
    Inland Fisheries and Wildlife, Maine State
    Planning Office, U.S. Fish and Wildlife Service,
    Wells National Estuarine Research Office, Maine
    Coastal Program, USGS, Southern Maine Regional
    Planning Commission, and The Nature Conservancy

Maine already has a lot of open space a rare
opportunity for preservation

  • Wildlife observation and bird watching
  • Walking
  • Bicycling
  • Skiing and snowshoeing
  • Historical study
  • Educational activities
  • Snowmobiling
  • Enjoying the peace and quiet!
  • Communing with nature
  • Spiritual renewal!!

Visions for the Future
  • As far at Cumberland Mills Dam could supports
    runs of 13,000 shad, 78,000 blueback herring, 20
    to 100 Atlantic Salmon and up to 20,000 alewives
  • Most of the area remains undeveloped, extensive
    opportunities to preserve open space, time is
    limited as development pressure is increasing
