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.

Carloe Brook Fish Passage Restoration Project, Washington County, Maine
-
This project will replace an undersized and failing stream crossing on Carloe Brook, a major tributary to Clifford Lake, a wild brook trout water. This stream crossing currently limits passage for trout and other aquatic organisms. The crossing will be replaced with a bottomless arch culvert designed to allow flows at all levels. This will open approximately 3 miles of passage for brook trout and other aquatic organisms.

Chop and Drop in Sunday River, Maine
-
The objectives of this project are to restore riverine and riparian habitats as well as to improve ecological stream processes for native brook trout in the Sunday River drainage. Stream habitats in this drainage have been degraded by poor land use practices, including timber harvesting, log driving, farming, and commerical and recreational development. A half mile long treatment of each of two tributaries will receive woody debris. These tributaries and a nearby control will be monitored for geomorphic, chemical, biological, and flow responses.

Chop and Drop in the Sunday River, Maine
-
Brook trout habitat in the Sunday River drainage has been degraded by poor land use practices, including
timber harvesting, log driving, farming, and commercial and recreational development. Much of the river
and its tributaries are unstable, over-widened, and lacking in deep pools, thereby reducing nursery and
adult brook trout habitat. Although degradation is being addressed through a comprehensive watershed survey and main-stem restoration effort, the causal problem of accelerated runoff has not been addressed. This proposal will assess the efficacy of adding woody debris to reduce peak flows, create pools, and trap organics to enrich depauperate headwater streams.

Enhancing Connectivity in the Ash-Black Rock Subbasin of the WB Narraguagus River, Maine
-
This project will replace two poorly functioning culverts with open bottom arch culverts to allow unhindered fish passage and restore overall ecological stream connectivity. Once complete, the project will open 4.3 miles of habitat from Ash Bog Stream to Black Rock Brook which flows to the West Branch of the Narraguagus River.

In-Stream Habitat Restoration in the Meduxnekeag Watershed, Maine
-
This project will restore 1.9 miles of habitat on the Meduxnekeag River mainstem and 0.25 miles of habitat on its north branch for brook trout within trust land for the Houlton Band of Maliseet Indians. The project will return the river to a more natural, sustainable state of in-stream habitat complexity, increase brook trout habitat quality, and promote interest in future restoration activities.

Jam Black Brook Culvert Replacement in Searsmont, Maine
-
This project will remove two improperly placed culverts and replace them with a single, bottomless arch culvert to allow brook trout and Atlantic salmon to access over 10 miles of high quality habitat in Jam Black Brook. It will also improve angling opportunities in Jam Black Brook and the St. Georges River.

Marshall Brook Culvert Replacement, Hancock County, Maine
-
This project will replace two existing undersized, improperly set round culvert inhibiting fish passage at the road / stream crossing of Marshall Brook with the Seal Cove Road in Southwest Harbor, Maine with an open bottom culvert. This will provide 4 miles of passage and reconnect a historic sea run brook trout stream with the estuary at Bass Harbor.

Relocation of an Unnamed Sea-Run Brook Trout Stream, Maine
-
This project seeks to reconnect the freshwater-estuarine interface on a historic sea-run brook trout stream. At some point in the past, the stream channel was diverted from its natural channel to its present location. The presence of a low-head dam and two marginally passable culverts have blocked connectivity to the marine environment for several decades. A partially degraded stream channel will be relocated back to its original position and rehabilitated to its historic function to allow brook trout to access both freshwater and marine environments. Once complete, the project will provide access to approximately 1 mile of stream habitat and an undetermined amount of marine habitat.

Restoration of Native Charr in Big Wadleigh Pond Maine
-
This project will restore 157 acres of habitat for native brook trout and arctic charr in Big Wadleigh Pond in northwest Maine by collecting eggs/brook stock from the dwindling adult populations and rearing them in a private hatchery while the pond is chemically treated to eliminate an illegal introduction of rainbow smelt. Restoration will also benefit anglers at this unique and popular fishing destination.
