Franklins Lake
Franklins Lake is currently struggling with critically low dissolved oxygen (DO) levels, and a combination of environmental factors has contributed to this decline. Prolonged periods of high pressure, minimal wind, and the seasonal breakdown of organic matter, including autumnal weed die-off and leaf drop, have created a scenario where oxygen levels are dropping faster than they can be replenished.
In normal conditions, wind plays a vital role in agitating the lake’s surface, allowing oxygen from the air to dissolve into the water. This mixing action is essential, especially during seasonal changes when plant material starts to decay and releases natural oils. These oils would typically be pushed to the edges by the wind, keeping the main body of water clear and able to absorb oxygen. However, with unusually calm weather and almost no wind, these oils have instead formed a film over the lake’s surface, effectively capping it and preventing adequate oxygen exchange.
The demand for oxygen in Franklins Lake is especially high right now. Fish and other aquatic organisms rely on DO for survival, and the decomposition of organic material also consumes oxygen, further straining the system. Without sufficient surface agitation, Franklins Lake cannot meet the oxygen demand below, putting fish and other life forms at risk. This situation is concerning, as it highlights the lake’s vulnerability to prolonged weather patterns and seasonal changes.
Due to these critically low dissolved oxygen levels, Franklins Lake will be closed until further notice. This measure is necessary to protect the aquatic life within the lake, as additional activity could further stress an already vulnerable ecosystem. Closing the lake allows us to monitor and manage the situation closely, giving the lake a chance to stabilize without added disturbance. We appreciate everyone’s understanding and patience as we work to address these environmental challenges and restore healthy conditions in the lake.
