Restoring Stream Habitat Connectivity in WB Machias, Maine
The primary threat to brook trout in the WB Machias River is associated with the aging road network. Project SHARE and the MEFRO have recently completed a basin wide stream-road crossing and fisheries assessment in the WB Machias River. There are 41 fish bearing road crossings in the subbasin that limit aquatic habitat connectivity. To date, six barrier removals / renovations have been completed. This project will remove another six barriers in the WB Machias in Maine.

Assessing the Efficacy of Remediating Episodic Low pH concentrations in Headwater Brook Trout Streams with Clam Shell Additions, Maine
This project will assess if clam shell additions will increase in-stream pH and decrease organic aluminum concentrations in headwater brook trout streams in Maine. Two tributaries included in this study currently do not sustain fish, even though they contain high quality habitat for fish. The likely reason for fish absence is thought to be low pH and subsequently high aluminum. The clam shell industry in Maine currently pays for discarding shells shucked at processing facilities. If this project is successful, it would allow us to use a waste product to help remediate low pH and subsequent high labial aluminum issues in brook trout streams.

South Bog Stream Restoration Project, Maine
South Bog Stream is a tributary of Rangeley Lake in Franklin County, Maine. Historically, the stream was known as the lake’s primary brook trout spawning tributary and it still supports a population of wild brook trout. However, Rangeley Lake, once known for its large brook trout, no longer has a thriving wild brook trout fishery. South Bog Stream no longer contributes a substantial number of brook trout to the lake. This fact is one possible reason for the decline of Rangeley’s renowned brook trout fishery. A 2001 stream survey revealed habitat degradation along the lower reaches of the 6.3-milelong stream, presumably as a result of the log-driving era in the late 1800s and early 1900s. Sections of the stream are shallow and wide. There are very few deep pools which provide essential habitat for brook trout. Because of habitat degradation, the stream produces fewer trout than it did prior to stream alterations over a century ago. The Maine Department of Inland Fisheries and Wildlife is restoring sections of the stream by rebuilding pools, narrowing and deepening the channel.

File Assessing the Efficacy of Remediating Episodic Low pH (and High Aluminum) Concentrations in Headwater Brook Trout Streams with Clam Shell Additions_FY09 Project
This project demonstrated that clam shells could be utilized to increase pH and decrease detrimental inorganic aluminum concentrations. In Dead Stream, water chemistry has improved by approximately 1.0 pH unit, and total fish densities increased two-fold. In Canaan Brook water chemistry has improved by 1.0 pH unit and First Lake Stream improved by 0.7 pH unit, while fish densities have increased 2- and 6- times, respectively. Macroinvertebrate communities have improved somewhat, especially among mayflies and stoneflies, while amphipods and snails have appeared for the first time. However, even at treated sites, macroinvertebrate communities continue to have low diversity and may not achieve Class A water quality. Overall, by adding buffering capacity, there has been a boost to the bottom of the food chain which has contributed to improved fish abundance and diversity. In the fourth year, biological communities are still adapting to the new conditions.

File Carloe Brook Fish Passage Restoration, ME_FY11 Project
The project replaced an undersized and failing stream crossing on Carloe Brook a major tributary to Clifford Lake that has wild brook trout. This stream crossing currently limits passage for trout and other aquatic organisms. The current crossing is also a significant sediment source due to improper construction and overtopping. The crossing was replaced with a 1.2 bankfull open bottom arch culvert (15ft wide) designed to allow passage at all flows.

File Restoring habitat connectivity in Machias and Saint Croix River tributary streams, ME_FY11 Project
Through this project, Downeast Lakes Land Trust (DLLT) continued its work with partners to restore brook trout habitat on priority streams within its 55,678-acre Downeast Lakes Community Forest by removing passage barriers. Of the four sites included in the original proposal (Billy Brown Brook/Shaw St., Amazon Brook/Amazon Rd., Grand Lake Brook/Fourth Lake Rd., and Fourth Lake Trib./Belden Brook Rd), two were completed using NRCS funding received after the initial proposal was submitted to USFWS. As a result, Eastern Brook Trout Joint Venture funding was used to restore fish passage at two additional sites at South Branch/Little River Rd and Towers Brook/Little River Rd.

File chemical/x-pdb Jam Black Brook Culvert Replacement, ME_FY12 Project
The goals of the project were: (1) To remove an obstruction to upstream fish passage for brook trout, Atlantic salmon and other resident and migratory fish. (2) To restore access to 9.8 miles of stream habitat upstream of the obstruction. (3) To restore natural sediment and woody debris transport through the crossing site. (4) To improve flood capacity at the Magog Road crossing, reducing the risk of debris jams or overtopping the road. (5) To provide a demonstration site in mid‐coast Maine for an appropriate stream crossing developed in cooperation with the municipality.

The Conservation Stewardship Program (CSP) helps agricultural producers maintain and improve their existing conservation systems and adopt additional conservation activities to address priority resources concerns. Participants earn CSP payments for conservation performance—the higher the performance, the higher the payment.
