TO PROMOTE THE PRESERVATION, CONSERVATION AND ENVIROMENTAL PROTECTION OF TIOUGHNIOGA LAKE AND ITS WATERSHED.

profile · synthesized from sources

Tioughnioga Lake Preservation Foundation works to protect and improve the environmental health of DeRuyter Lake and its watershed in central New York. The organization addresses water quality issues caused by stormwater runoff, invasive species, and nutrient loading through science-based projects and community engagement. It collaborates with environmental engineers, biologists, and government agencies to implement conservation strategies and secure grant funding for long-term lake preservation.

  • Lake Invasive Species Management 3 activities
    • Biological lake restoration using walleye stocking
      Stocks walleye fingerlings in DeRuyter Lake over multiple years to biologically control populations of small fish that consume insects which naturally feed on invasive milfoil.
    • Mechanical and seasonal aquatic weed management
      Conducts mechanical and seasonal harvesting of aquatic weeds such as curly leaf pondweed and milfoil to control overgrowth and maintain ecological balance in DeRuyter Lake.
    • Prevention of invasive species spread via boat cleaning stations
      Installed informational signage and portable boat cleaning stations at lake access points to promote the "Clean, Drain, Dry" protocol and prevent the spread of invasive species.
  • Lake and Watershed Monitoring & Assessment 2 activities
    • Stream input assessment and erosion control planning
      Hired an environmental engineering firm in 2019 to assess 11 stream inputs into DeRuyter Lake, resulting in a report with conceptual designs and cost estimates for streambed stabilization and riparian buffer implementation.
    • Water quality monitoring and data collection
      Contracts with scientific institutions such as the Upstate Freshwater Institute to conduct monthly water flow and nutrient testing, including during high-flow storm events, to inform management decisions and support grant applications.
  • Environmental Conservation Grantmaking 1 activity
    • Funding research on lake biology and watershed management
      Provides financial support for scientific research on the biology, fish, plants, wastewater systems, and watershed management of DeRuyter Lake, including funding for a watershed management study assessing nutrient loading and its impacts on aquatic vegetation.
  • Uncategorized 1 activity
    • Testing innovative technologies for algae bloom control
      Served as a test site in summer 2020 for a drone-directed, ultraviolet-light-emitting semisubmersible device designed to kill harmful algae blooms, in collaboration with Eget Liber.

How they approach the work

Named approaches extracted from this org’s sources. Where others share an approach, follow it to see the full set of orgs running it.

  • Community-Integrated Stewardship
    methodology: community-governed stewardship
    By aligning lake preservation with community stakeholders and engaging volunteers in stewardship activities, we enhance program legitimacy and long-term sustainability because local ownership increases compliance, participation, and behavioral change.
  • Ecosystem-Based Watershed Management
    methodology: ecosystem-based management
    By managing Tioughnioga Lake and its surrounding watershed as a unified ecological system, we achieve sustainable water quality and ecological preservation because interventions are aligned with natural hydrological and biological processes.
  • Science-Guided Non-Chemical Intervention
    methodology: evidence-based management
    By using non-chemical, research-based methods such as mechanical harvesting, benthic barriers, and UV treatment to control invasive species and algae, we maintain ecological balance because these methods reduce unintended environmental harm while effectively targeting problem species.
