Bathymetry Mapping and Sediment Sampling: The EPA collected data in June of 2025 and worked over the winter to render new bathymetry maps of the lake bottom. This updated information helped us determine the locations for sediment cores to be collected by Maine DEP and our staff this fall. The map is available in meters and feet.
Engineering Peer Review Study: Our engineering consultants at VHB met with community members with local knowledge of the Dead River pollution control device (“dam”) operations and maintenance. VHB has nearly completed their peer review of the previously completed E-Pro engineering study from 2002-03. Their review focused on assessing consistency in methodology, data sources, and study results with current engineering best practices, as well as suggestions for future modeling or investigations.
Agricultural Surveys: In mid-July, our environmental consultant Ecological Instincts completed their agricultural field survey to verify land cover types for their land cover analysis. Assessing land cover helps determine the extent of nutrients and sediments that could be entering the lake from the watershed.
Grant Funding Updates: The Town of Wayne has been conditionally awarded a Maine DEP 604(b) grant of $80k from the proposal that 30 Mile submitted in May for the Androscoggin Lake Watershed-Based Plan Development Project. 30 Mile will be managing this grant and overseeing the work to be completed.
Monitoring Buoy: Please do not approach the buoy. This buoy is anchored and its mooring line contains sensors that can be damaged if snagged.
On August 5th, we deployed a continuous monitoring buoy at the deep hole monitoring station of the lake. It collects data around the clock at the surface and bottom of the lake. This buoy will not replace our bi-weekly monitoring and sampling efforts, but will provide additional data, notifying us exactly when changes in the lake occur. It will also predict when and where toxins could be present and concentrating along shorelines, based on wind and wave information. This buoy is contracted by Subtidal.
On August 14th, the buoy was removed due to malfunctions. A new buoy will be installed tomorrow. For updates on when the buoy’s dashboard will be available and for additional details relating to this work, visit the Androscoggin Bloom page.
