Water Quality Reports

Water Quality Reports of Lake Glenville are currently provided on a quarterly basis courtesy of Equniox Environmental. Other reporting is conducted by FLG members and volunteers.

Friends of Lake Glenville’s Water Quality program is one of our organization’s key and most important elements of our mission. The program currently has three major parts: 

  1. Stream or in-flow water testing
  2. Lake water testing
  3. Lake sedimentation measurement.

A fourth part, fishing improvement, is being activated.

These programs are funded by FLG dues and donors and are only effective through the efforts of our generous donors and volunteers.

Stream or In-Flow Testing

Water samples are periodically collected from our five major in-flows and sent to a lab for chemical and turbidity testing. The purpose is to monitor and evaluate the quality of water flowing into the lake. Clean water coming in to the lake should provide clean water in the lake. The early seven years of stream testing was conducted using the macro-invertebrate methods. The follow on twelve years we have used sample collection and laboratory methods. Our data is referenced in the North Carolina State Little Tennessee Water Basin documentation.

Lake Water Testing

At the cornerstone of FLG’s mission to preserve and protect Lake Glenville is our work to monitor the lake’s water quality and implement the measures we can to ensure it remains one of the cleanest lakes in Western Carolina and is healthy and safe for all those who live, work, and play around it. Our partnership with Equinox Environmental allows us to do just that.

Historically, FLG has made water quality and the long-term health of Lake Glenville our primary purpose. To accomplish this, we rely heavily on regular testing of the lake and tributaries that feed into it. Over the years, our methods have evolved from dedicated individuals donating their time and expertise to outsourcing the scientific work for several years to Western Carolina University.

The onset of a global pandemic made it clear, however, that we needed a consistent and professionally managed strategy that would ensure this vital work could continue regardless of circumstance. In 2020, FLG was awarded a grant from Duke Energy to support and continue to improve FLG’s water testing program. That grant allowed us to establish a partnership with Equinox Environmental, an environmental consulting company focused on conservation and environmental responsibility. Equinox provides the consistency, expertise, and reliability we need to have a successful and on-going program.

How Can You Track the Results?

As part of that multifaceted partnership, Equinox performs testing and provides comprehensive reporting that helps educate our members and inform the local community regarding FLG’s work. These reports are made available to our membership and interested stakeholders by publishing them here on our website.

Forging a Path Forward

In order for FLG to truly preserve and protect Lake Glenville for generations to come, it’s imperative the work we do has the same longevity in both impact and effect. This is why the FLG Board recently engaged Equinox to establish a long-term Comprehensive Watershed Management Plan.

Visionary in its design, this plan provides a roadmap moving forward, guiding FLG toward a future where our work is proactive rather than reactive. Additionally, we will use this as a tool to work with key stakeholders like Duke Energy, Jackson County, NCDWR and others to continue the pursuit of FLG's goal to preserve and protect Lake Glenville.

Lake Turbidity

The purpose is to identify the sources of lake sedimentation and to attempt to quantify the turbidity contribution by each source. This work includes the identification of types and amounts of algae contributing to the lake turbidity. Secchi disk measurements are used to quantify the clarity of the lake waters. Once a year a secchi disk reading is reported to a national data base.

Fishing Improvement

Working with the state fisheries we want to identify and implement improvements for lake fishing enjoyment.
