Lake UpdateWe saw an initially slow rise during the spring season of water in the lake, and are now seeing fluctuating water levels that are very responsive to rainfall and temperatures. Currently, the lake is still low and several feet from the floating "T-dock" down by the water. A team of scientists from Radford University has been studying the lake since last fall with a geological engineering perspective. We had mentioned how they implemented a tracer dye test this past winter and early spring in hopes of determining exactly where the outflow of water through the bottom of the lakebed is going. This test yielded telling results - the fluorescein dye did not show up conclusively in any of the major surface streams near the mountain top, including Pond Drain (originally thought to be the main outflow of water from the lake). What this means is that the water may be held up underground for some period of time, perhaps in a reservoir of sorts, or that the water may flow through the fissures in the lake bottom further down under the mountain and surface streams. The scientists hope to repeat the dye test again in the future, surveying for the dye in underground streams and points near the foot of the mountain.

Please remember to use caution and respect when exploring the lake and lake bed. The pontoon boat has been outfitted for the scientists, divers and their equipment. DO NOT DISTURB ANY RESEARCH EQUIPMENT OR BOATS. Although the lake is low, the water is still very deep, up to 40 feet in some areas. Swimming in the lake is AT YOUR OWN RISK, and we do not encourage swimming or fishing at this time.
