Low pH, in conjunction with low levels of calcium, and high levels of biologically available aluminum in five Downeast rivers may be significantly impacting the ability of Atlantic salmon smolts to effectively transition between their natal freshwater environment and the salt water environment where they spend their adult life. Given the critical status of Atlantic salmon stocks within the State of Maine, NOAA-Fisheries and the Maine Atlantic Salmon Commission, in collaboration with other government and non-government partners, plan to implement a pilot liming project on the Dennys River to evaluate the effectiveness in minimizing deleterious water chemistry affects on salmon survival. Based on water chemistry parameters, stream flow, and biological factors, current plans are to construct a fully computer-automated liming doser at the Rt. 86 Bridge in Dennysville Station. This doser will apply a calcium carbonate solution during runoff events (i.e. rain, snow melt, etc.) that often result in low pH, low calcium, and high aluminum levels. Historic information indicates that these events most often occur between late October and late May of each year; however, they may occur at other times of the year. Project Scope: Sampling of aquatic vegetation, including algae, shall be conducted in each of the distinct habitat types (lentic and lotic) at and below bank full elevation encountered in the segment of the Dennys River targeted for lime treatment. Additionally, sampling shall be conducted at control sites representing similar habitat types above the targeted treatment segment. The sampling shall be conducted during the growing season prior to the lime treatment and the growing season immediately following the first lime treatment. Sampling shall be conducted in a manner that clearly documents any changes in aquatic plant communities that may be associated with the lime treatment. Deliverables: · Summary report of methods, location of sites (GPS coordinates), species lists, descriptions of documented habitat types, and comparisons of species composition and abundance among habitat types. Report should also include findings, including documentation of rare or unusual plant communities; conclusions; and recommendations. · Electronic copy of data in a Microsoft office compatible format. Preferably Microsoft Excel. · Site photos, coordinates, and maps of the sites that are sampled
