THE WITHLACOOCHEE RIVER AT DUNNELLON HAD BEEN STEADILY RISING SINCE
JULY, AND ON SEPTEMBER 15 REACHED FLOOD STAGE. THE CAUSE OF THE HIGH
WATER ALONG THE WITHLACOOCHEE RIVER AT DUNNELLON IS DUE TO EXCESSIVE
HYDRILLA GROWTH (FROM THE RIVER BOTTOM TO THE WATER SURFACE) ALONG A
4.5 MILE STRETCH OF RIVER BETWEEN US 41 AND LAKE ROUSSEAU. THE
HYDRILLA IS ACTING LIKE A DAM AND HOLDING WATER BACK, CAUSING WATER
LEVELS TO RISE. HOWEVER, DUE TO RECENT AND FORECAST DRY CONDITIONS,
THE RIVER HAS NOW FALLEN INTO ACTION STAGE, WHERE IT IS CURRENTLY
EXPECTED TO REMAIN.
