Investigating the Aftermath: Analyzing Fish Populations in Douglas Lake post-Hurricane Helene
East Tennessee scientists assess fish population after Hurricane Helene's impact
After seven months, researchers are finally diving into Douglas Lake in Dandridge, Tennessee to analyze the effects of Hurricane Helene on its fish populations. The Tennessee Valley Authority (TVA) fisheries biologists are examining the fish populations for the first time since the hurricane, with the goal of understanding the potential damage excessive debris might have had on the region's popular sport fish.
Scientists are employing a unique method to examine the fish: shocking the water to tense the muscles of all fish within a four-foot radius of their research boat. Once the fish float to the surface, they are meticulously examined, measured, and weighed before being safely released back into the water.
Preliminary data collected could indicate the impact the debris has had on the sport fish population in Douglas Lake. Comparisons will be made to similar surveys on the lake over the past 30 years to gauge any significant differences. A drop in fish numbers or fish with physical defects, parasites, or injuries could be cause for concern, particularly heading into the spawning season.
The health of Douglas Lake's fish populations is crucial, considering about 80% of the tourism in the area is attributed to sport fishing, bringing in hundreds of thousands of dollars annually.
"We have other events, of course. We have festivals. We have a lot of other things in Jefferson County, but the lake is our bread and butter," Skylar Hamilton, from the Jefferson County Tourism Department, said.
As cleanup efforts on Douglas Lake are almost complete, with over 112,000 cubic yards of debris removed from 351 miles of shoreline, the protection and recovery of the lake's fish populations remain vital for the region's economy.
