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.

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.

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.

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.

USDA Conservation Stewardship Program
-
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.

Restoring Connectivity in the Sunday River and Martin Stream Watersheds, Maine
-
Subwatersheds of the Androscoggin River contain some of the finest intact and healthy brook trout habitat in the state of Maine. This project will remove two fish passage barriers providing a total of six miles of connectivity in the Sunday River and Martin Stream subwatersheds.
