  • 2019 Volunteer Manual Saco River Corridor Commission
    Volunteer: _________________________________ Site(s): ____________________________________ 2019 Volunteer Manual Saco River Corridor Commission 2019 RIVERS Water Quality Monitoring Program is coordinated by: Dear RIVERS Volunteer, On behalf of Green Mountain Conservation Group and the Saco River Corridor Commission we would like to thank you for volunteering with the 2019 RIVERS Water Quality Monitoring Program. Since 2001, the Regional Interstate Volunteers for the Ecosystems and Rivers of Saco (RIVERS) program has depended on dedicated community members to conduct high quality citizen science in the Saco/Ossipee Watershed. By volunteering with RIVERS, you are collecting data to better understand the water quality in our area. You are helping to identify locations where water quality has been impacted, in addition to collecting valuable baseline data that can be utilized in planning for future regional development. While science is our goal, your safety is our top priority. Data collection is nice, but not at the expense of your well-being. If at any point in time you feel unsafe at your site, discontinue monitoring and leave. This includes but is not limited to high waters, suspicious persons, or inclement weather. Follow your gut, and only do what you feel comfortable with. Reach out to your volunteer coordinator if you have any issues or concerns about the program, even while out sampling. We want to help you if you get stuck on what to do, are having equipment issues, or have general comments on how to improve the program. We are here to help and value feedback from our volunteers. The RIVERS program is only successful because of you - our intrepid, boots-on-the-ground volunteer group.

  • Survival and Movement of Fall-Stocked Brown Trout in the Lower Saco River
    Fishery Final Report Series No. 16-2 Survival and Movement of Fall-Stocked Brown Trout in the Lower Saco River By: Francis C. Brautigam Sebago Region December 2016 Maine Department of Inland Fisheries & Wildlife Fisheries and Hatcheries Division Job F-012 Survival and Movement of Fall-Stocked Brown Trout in the Lower Saco River Final Report No. 16-2 SUMMARY A telemetry study was conducted to assess the survival and movement of hatchery brown trout stocked in the lower 13.1 mile portion of the Saco River. For more than 10 years this river reach has been managed under special fishing regulations to allow year-round fishing and recreational harvest. Most Maine rivers and streams are open to recreational fishing from April through September. Fifty-nine fall yearling hatchery brown trout were equipped with radio transmitters and stocked below Skelton Dam (Town of Dayton) in the fall of 2013. All stocked fish were of a size that could be legally harvested by anglers. The movement and survival of these fish were monitored from October 2013 through August of 2014 using a portable and stationary receiver. Transmission signals indicated 64% of the study fish were alive within the 13.1 mile long study reach two months after stocking. By May of 2014 transmission signals were detected from 25% of the study fish, and by August (2014) signals were detected from 3% of the study fish. Transmitters were equipped with mortality switches, which were permanently activated in 44% of the fish over the course of the study. Monthly mortality was low throughout the study, with the heaviest mortality observed between March and May.

  • Introduction
    Mousam River near Sanford, Maine The majority of sampling effort in the Salmon Falls basin has focused on stations on the mainstem affected by dams and wastewater discharges. The Salmon Falls River has been managed as Class B for many years but has experienced continual problems attaining Class B standards for dissolved oxygen, bacteria and aquatic life, in the lower reaches,. All aquatic life monitoring stations downstream of the Berwick sewage treatment plant fail to attain assigned Class B standards. Introduction Geography The Saco River basin covers 1,696 square miles. The River originates at Saco Lake just north of Crawford Notch, New Hampshire and flows through the Mt. Washington Valley. About half of the drainage area is in the State of New Hampshire. Just east of Conway, New Hampshire it crosses into Maine, near Fryeburg, winds northeast for a short distance, and then meanders south- southeast through the mountains and hills of Western Maine. The Saco River continues southeast towards the urban coastal areas of Biddeford and Saco before emptying into Saco Bay. The total length from the Maine/New Hampshire border is approximately 85 miles. There are four other sampled streams in the Saco River basin listed in Basin Table 9. The Piscataqua/Salmon Falls River basin covers 1,356 sq. miles. The Piscataqua River is the tidal portion of the Salmon Falls River. The Biological Monitoring Program has not conducted any sampling in the tidal portions of the river so the remainder of this report will focus on the Salmon Falls River. For its entire length, including below head of tide, the River forms the Maine/New Hampshire border.

The zone is widest in southwestern Maine, the area, of this field % r trip (Figure 1). The most significant of the faults within the zone in southwestern Maine appears to be the Flying Point Fault (Fig.l). South of Scarboro, the fault zone is represented by the Nonesuch River Fault with which the Flying Point Fault merges. The Nonesuch River Fault continues into New Hampshire where it apparently is the same break as the Campbell Hill Fault of Lyons, et al.
