The Adirondack Lakes Survey Corporation (ALSC) and Adirondack Long-Term Monitoring (ALTM) cooperators have provided key scientific results to New York State and Federal policy makers regarding atmospheric pollutants from emissions. The efforts of the ALSC and ALTM cooperators have helped show a marked recovery from acid deposition within the Adirondack Park. The ALSC is continuing ALTM efforts and is also working with the New York State Department of Environmental Conservation (NYSDEC) on additional brook trout restoration efforts.

As the Adirondacks recover from decades of acid deposition, the opportunity may now exist to restore brook populations to many historical waters. For brook trout recovery efforts to be successful, fisheries managers need to be provided with key metrics to ensure that appropriate waters are selected for reintroduction. The suitable acid-base chemistry of a given water should represent a dynamic that allows survival, growth, and ultimately reproduction of the fishery. Additional chemical analysis by the ALSC may also help NYSDEC identify natural spawning waters. This analysis could result in future significant cost savings to the NYSDEC. This poster will show current efforts by the ALSC to help NYSDEC with key brook trout restoration efforts in the Adirondack Pak that is recovering from acid deposition.
