Description of Work Studies assessing seasonal and spatial changes in digestive enzymes and gill raker morphology in bigheaded carps and native planktivorous fishes have been completed. Results indicate that bigheaded carps feed earlier in the year than native filter-feeding fishes and that certain digestive enzymes present in bigheaded carps are either not present in some native fishes or are much less active in the native species than in bigheaded carps. Results also indicate that the gill raker morphology of bigheaded carps is relatively constant with minimal seasonally or spatially relevant changes unlike that of the native gizzard shad (Dorosoma cepedianum) which had both seasonal and spatially correlated changes...

Description of Work Past water-quality issues in the St. Lawrence River at Massena, NY resulted in a determination that selected beneficial uses may be impaired in a surrounding Area of Concern (AOC) and on the Canadian side of the international boundary (Cornwall, Ontario). The plankton (phytoplankton and zooplankton) Beneficial Use Impairment (BUI) was so designated because impairment metrics were unavailable or inconclusive. Recent investigations, however, suggest that plankton communities are relatively healthy and no longer threaten the local ecosystem. Thus, the BUI for plankton may now be outdated in all, or parts of, the St. Lawrence River in the Massena AOC. The primary goal for the Massena (and Cornwall)...

Monthly water yields for 105,829 catchments and corresponding flows for 107,691 stream segments were estimated for water years 1951-2012 in the United States part of the Great Lakes Basin. Estimates were computed using the AFINCH (Analysis of Flows In Networks of CHannels) application within the NHDPlus geospatial data framework. AFINCH provides an environment to develop constrained regression models to integrate monthly streamflow and water-use data with monthly climatic data and fixed basin characteristics data available within NHDPlus or supplied by the user. Monthly flow time series for individual stream segments can be retrieved and used to approximate monthly flow duration characteristics and to identify possible...
