Johns Lake Quality Indicators
Over the years, the Johns Lake Improvement Association (JLIA) has dealt with numerous potential problems and threats to Johns Lake. JLIA has recently identified five Quality Indicators that will be monitored and reported in the newsletters moving forward. They included Lake Levels, Water Quality, Invasive Vegetation, Drainage, and Habitat.
An easy to understand reporting tool has been developed using a stoplight approach with a brief explanation for each quality indicator. The JLIA will use data provided from the county and other organizations and will make some subjective measurements. The intent is for lakefront owners to be able to easily see where the JLIA feels issues involving the lake need attention or additional discussion in the newsletters.
Let’s all continue to do our part to keep Johns Lake an enjoyable place to live!
Improving
The lake level has receded somewhat from the recent high level but significant rainfall or future hurricanes could push it too high. With reduced rainfall at this time, the trend here is improving.
Also, we are hopeful that the county will maintain the drainage canal to Lake Apopka after their study is completed. A county study is underway to do an assessment and recommend options to address this important issue.
Stable
Water quality has been steadily improving during the past ten years according to county testing. Long-term, frequent participants in lake sports activities (skiing, wake-boarding) have reported a significant improvement in water clarity.
Improving
Hydrilla, Cuban Bulrush, and other invasive species are an ongoing concern for Johns Lake. The county will continue to treat as needed and additional grass-eating carp will be added to the lake to augment their efforts. This quality indicator is constantly changing and a combination of weather and treatments can affect the status either way.
Being Studied
Johns Lake drainage (aka outfall) is an ongoing concern. Recent water levels are higher than previous years and there is a concern that the current outflow is not sufficient. We will keep you posted on this issue.
Stable
Even with the new developments around Johns Lake it is still a vibrant habitat for wildlife. We have otters, alligators, turtles, bald eagles, osprey, ducks and many other species of water fowl. And, as always, the lake is a premier fishing site.
