Removal of Two Dams in the Wetmore Run Watershed, PA_FY12 Project: As part of a plan to upgrade their public water supply to a non-dam alternative, the Borough of Galeton agreed to remove two dams and their associated impoundments. The dams were located on Wetmore Run and Right Branch of Wetmore Run, Potter County, PA. Both streams are classified as High Quality – Coldwater Fishery (HQ – CWF) by the Pennsylvania Department of Environmental Protection (PA DEP) and drain a predominantly forested watershed comprised of ~60% public land. The barriers blocked upstream Brook Trout passage to approximately 8.5 miles of headwater habitat, contributed to the elevation of instream temperatures, interrupted the natural flow regime, and negatively impacted ecosystem function. As a result of the dam removals, almost 8.5 miles of headwater habitat was reconnected to the rest of the upper Pine Creek Watershed, which contains several intact eastern Brook Trout populations.

Response of fish assemblages to declining acidic deposition in Adirondack Mountain lakes, 1984-2012: Adverse effects of acidic deposition on the chemistry and fish communities were evident in Adirondack Mountain lakes during the 1980s and 1990s. Fish assemblages and water chemistry in 43 Adirondack Long-Term Monitoring (ALTM) lakes were sampled by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation during three periods (1984-87, 1994-2005, and 2008-12) to document regional impacts and potential biological recovery associated with the 1990 amendments to the 1963 Clean Air Act (CAA). We assessed standardized data from 43 lakes sampled during the three periods to quantify the response of fish-community richness, total fish abundance, and brook trout (Salvelinus fontinalis) abundance to declining acidity that resulted from changes in U.S. airquality management between 1984 and 2012. During the 28-year period, mean acid neutralizing capacity (ANC) increased significantly from 3 to 30 meq/L and mean inorganic monomeric Al concentrations decreased significantly from 2.22 to 0.66 mmol/L, yet mean species richness, all species or total catch per net night (CPNN), and brook trout CPNN did not change significantly in the 43 lakes. Regression analyses indicate that fishery metrics were not directly related to the degree of chemical recovery and that brook trout CPNN may actually have declined with increasing ANC. While the richness of fish communities increased with increasing ANC as anticipated in several Adirondack lakes, observed improvements in water quality associated with the CAA have generally failed to produce detectable shifts in fish assemblages within a large number of ALTM lakes. Additional time may simply be needed for biological recovery to progress, or else more proactive efforts may be necessary to restore natural fish assemblages in Adirondack lakes in which water chemistry is steadily recovering from acidification.

Restoration of Riverine Process and Habitat Suitability In the Upper Narraguagus River and Northern Stream Focus Areas (Maine): This project decreases embeddedness by mobilizing the river bed, increasing sediment sorting; increases the number and depth of pools; increases retention of allochthonous organic material that the aquatic food web relies on; reduces the dead waters and over-widened channels in legacy reservoirs; and, increases cold-water fish population resiliency to climate change. The project cost is $155,737 and the estimated socioeconomic benefit is $1.6 million.

Restoring a Brook Trout Metapopulation within the Little Cataloochee Creek & Anthony Creek Watersheds, Great Smoky Mountains National Park: The project will result in the removal of Rainbow Trout from 1.6 stream miles of the Little Cataloochee and 1.7 stream miles of Anthony Creek watersheds. Successful removal of these invasive fish will allow native Brook Trout to be re-introduced into these stream reaches. Total project cost is $234,112.

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.

Sampling strategies for estimating brook trout effective population size: The influence of sampling strategy on estimates of effective population size (Ne) from single-sample genetic methods has not been rigorously examined, though these methods are increasingly used. For headwater salmonids, spatially close kin association among age-0 individuals suggests that sampling strategy (number of individuals and location from which they are collected) will influence estimates of Ne through family representation effects. We collected age-0 brook trout by completely sampling three headwater habitat patches, and used microsatellite data and empirically parameterized simulations to test the effects of different combinations of sample size (S = 25, 50, 75, 100, 150, or 200) and number of equally-spaced sample starting locations (SL = 1, 2, 3, 4, or random) on estimates of mean family size and effective number of breeders (Nb). Both S and SL had a strong influence on estimates of mean family size and ^ Nb; however the strength of the effects varied among habitat patches that varied in family spatial distributions. The sampling strategy that resulted in an optimal balance between precise estimates of Nb and sampling effort regardless of family structure occurred with S = 75 and SL = 3. This strategy limited bias by ensuring samples contained individuals from a high proportion of available families while providing a large enough sample size for precise estimates. Because this sampling effort performed well for populations that vary in family structure, it should provide a generally applicable approach for genetic monitoring of iteroparous headwater stream fishes that have overlapping generations.
