Oakdale Lake Water Quality Improvement & Community Education Program

Hudson, NY

Great Ecology was contracted by the Columbia Land Conservancy and the Friends of Oakdale Lake to develop a water quality improvement plan for the 5-acre Oakdale Lake in Hudson, NY. Great Ecology managed extensive water quality assessments and developed a Citizen Scientist led water sampling program to understand existing conditions, track water quality changes on an annual basis, and collect other important data points such as mapping previously unknown stormwater outfalls in the watershed.
Data collected by volunteers was merged with additional sediment and benthic invertebrate sampling completed by Great Ecology to understand existing conditions and potential sources of water impairments. These studies revealed that Oakdale Lake contained excess nutrient loads as a result of runoff from the surrounding watershed, resulting in significant algae blooms leading to die-off of submerged aquatic vegetation (SAV) and depletion of oxygen. To address these issues, Great Ecology developed, and continues to support the implementation of, a multiple-year water quality management plan utilizing various methods such as barley straw application, SAV harvesting, and air diffuser usage.
As part of this project, Great Ecology has had the fantastic opportunity to connect with the Hudson community through educational sessions, town halls, and interactive field trips for local schools. This includes developing informational signage regarding lake conditions and management actions. Additionally, we have helped the Friends of Oakdale Lake coordinate with local public and private stakeholders to improve and maintain water quality, and identify future project opportunities for projects that may be eligible for public and private grant support.

Community Engagement for Project Success

Community engagement was not just a client priority for this project, but a critical success factor in meeting project goals within budgetary constraints. To support the project, Great Ecology trained and oversaw local volunteers in multi-season water quality sampling and used this data to develop the lake management recommendations.
Outside of the water, our team hosted local school children for interactive learning sessions where students learned about managing water quality, lake ecology, and filled barley straw bags used as part of the management plan.  We also hosted public meetings with the local Hudson community to discuss both the results of the testing program and our proposed management recommendations. To help the community better understand the current conditions and management options, we created a number of graphics for display in Hudson's public library.
