Excessive rain causes flooding on local road
Chattanooga has received more than four inches of rain since Friday and an inch and a half yesterday. With all this rain, creeks in our area are rising, causing flooding issues on some roads.
On Aster Avenue, in the Lookout Valley area, flood water has closed the road. The water on Aster Avenue should be emptying into Lookout Creek, but instead it is backed up, causing inconveniences for residents in the area.
Lookout Creek is under a flood warning until late Wednesday night, but the water is falling at this time.
Those living along Aster Avenue tell us it is common for the area to flood, but it does not usually reach anyone's home.
One person who has lived here for 7 years said the water has been in her backyard many times, but never up to her house.
"Usually it comes almost to that tree right there, up close to the road. It comes to that tree almost usually because usually there's barrels right there," explained longtime resident, Patrick Graham.
The water is lower now than it has been in previous floods, but may rise more after today's rain.
Graham said this is probably the third time just this year that the water has backed up and flooded the road.
It happens after heavy rain, multiple times a year, and takes 3 or 4 days to recede.
Unfortunately, his family is very accustomed to the flooding.
"Since the 60s, we've been here since the 60s. My great grandfather built this house, so we've been here through all the floods," Graham said.
Through the years, the street has changed appearances due to the flooding.
"There used to be houses out there. They used to be all the way up and down it. My grandparents used to live further down in about the middle of it," stated Graham.
Other people decided to stay in the neighborhood, but have taken action to prevent flood damage.
"The two houses on the end are jacked up now. They are off the ground pretty high," Graham pointed out.
Flooding is not only happening on Aster Avenue, but several flood warnings are active in our area.
Unlike flash flooding that happens immediately, flooding in rivers and creeks occur over time. They crest after the rain has stopped as runoff in the drainage basin slowly moves down into the creeks and then larger rivers.
TVA is working hard to manage the main Tennessee River system with their dams to minimize any flooding.
The Chickamauga Dam is spilling at 973,000 gallons per second. Only 173,000 gallons per second can be used for power generation. The rest is spilling for flood control.
TVA makes adjustments to their river forecasts and flow rates every 6 hours to keep the entire system running smoothly.
