ENVIRONMENTAL PROTECTION OF CHATEAUGAY LAKE.

profile · synthesized from sources

The Chateaugay Lake Foundation (CLF) is a nonprofit established in 2007 to protect the environmental quality of Chateaugay Lake in upstate New York. It focuses on controlling invasive species, particularly Eurasian watermilfoil, through direct removal, public education, and partnerships. The organization relies on private donations, grants, and fundraising events to support its conservation efforts.

What they call their work

Invasive Species Monitoring
Partners with organizations like the Adirondack Watershed Institute and APIPP to monitor for emerging threats including zebra mussels, hydrilla, spiny waterflea, and hemlock woolly adelgid.
Milfoil Control Project
Directly targets Eurasian watermilfoil through hand-harvesting, benthic matting, and suction harvesting across infested areas of Chateaugay Lake, focusing on high-spread-risk zones.
Public Education and Prevention
Runs outreach campaigns on "Clean, Drain, and Dry" protocols, proper bait use, and species identification to prevent the spread of invasive species.

What they do

  • Lake Invasive Species Management 4 activities
    • Annual Eurasian watermilfoil control on Chateaugay Lake
      Conducts annual invasive species management through hand-harvesting, benthic matting, and suction harvesting to remove Eurasian watermilfoil from Chateaugay Lake, with over 200 tons removed to date and 12 tons removed in 2022 alone. Activities focus on maintaining navigable boating lanes and reducing milfoil density in heavily infested areas.
    • Buoy deployment for navigation and awareness
      Deploys marker buoys in Upper and Lower Chateaugay Lakes to designate milfoil-free boating lanes and mark dense Eurasian watermilfoil beds, improving navigation safety and public awareness of infested areas. Installed new buoys in the inlet to Lower Chateaugay Lake in 2021.
    • Curlyleaf pondweed removal
      Removes curlyleaf pondweed from multiple locations in Upper and Lower Chateaugay Lakes as part of broader aquatic invasive species control efforts.
    • Mapping and monitoring of invasive aquatic plants
      Supports annual and periodic mapping of Eurasian watermilfoil bed locations, size, and density on Chateaugay Lake, including a full shoreline survey conducted in 2021 to inform treatment planning and measure ecological impact.

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.

  • Coordinated Multi-Partner Response Model
    methodology: coordinated_partnership_response
    By mobilizing a broad-based, coordinated partnership approach, the foundation enhances the scale and sustainability of invasive species response, because collaboration across stakeholders increases resource pooling, information sharing, and consistent action across jurisdictions.
  • Prevention through Early Detection and Public Engagement
    methodology: invasive_species_prevention
    By combining early detection of invasive species with public education and protocols like Clean, Drain, and Dry, the foundation prevents new introductions and slows spread, because recreational users are critical vectors whose behavior can be modified through outreach and clear practices.
  • Selective Removal with Native Species Preservation
    methodology: selective_removal_with_native_preservation
    By using trained divers to selectively remove invasive species like Eurasian milfoil, the foundation maintains ecological balance, because this method minimizes collateral damage to native aquatic plants and supports overall lake ecosystem resilience.
  • Targeted Source Control with Natural Force Consideration
    methodology: source-control_prioritization
    By prioritizing treatment of heavily infested areas that serve as sources for milfoil spread, the foundation reduces reinfestation risk and improves long-term control, because addressing these high-leverage points limits downstream dispersal via natural forces and human activity.
