MOUNTAIN ISLAND LAKE, N.C. (WBTV) - Some homeowners near Mountain Island Lake are looking for answers. Lake levels reached into homes, flooding and damaging property.
Some people feel Duke Energy didn’t give them enough advanced warning and they want to know what was Duke Energy doing? Why didn't the utility control the water levels?
"I would say that this storm and the amount of rainfall and the rate that the rain came was beyond our normal experience operating these plants,” said Michael Brissie. “And this is top four amount of rainfall that we've managed in 100 years of the system and so some of the numbers are unproven and did exceed our initial estimated."
Brissie, who is a General Manager of Hydro Operations, says the storm that passed though the upper Catawba near Morganton and Hickory on Saturday afternoon and evening dumped more than eight inches of rainfall. All that water from the upper Catawba made its way down the river.
“And as we worked through our predictions throughout the day on Sunday the volume of water continued to increase beyond our initial estimates,” said Brissie. “Going into the storm all of our lakes were at their target elevation. Saturday afternoon we began drawing them down. Mountain Island was down to 96 feet – four feet below full pond – which would be a good position for a normal storm. As I said this was a much larger storm than we’ve had experience with in the past and that’s why you see the rainfall that you do and the elevation rise.”
Some of the folks forced to evacuate their homes near Mountain Island Lake told WBTV that they didn’t get much notification that their homes were in danger of being flooded.
Brissie says Duke Energy did post updates to their websites and notified Mecklenburg County Emergency Management.
According to Duke Energy, at 9:30 Sunday morning they notified Mecklenburg County Emergency Management that Mountain Island “would exceed 102.5 feet.”
Duke says at 10:45 a.m. they updated their web message to say 104 feet.
The utility says at 1:40 p.m. their web message changed and said “not to exceed 105 feet.”
At 4 p.m. they said “it will not exceed 106 feet.”
But Duke Energy says at 6 o’clock Sunday they reported that the lake “will exceed 106 feet.”
“We updated our forecasting and lake levels and flooding levels as soon as we get them. There was a whole lot more water than we’re used to managing coming at us yesterday as well as inflows from additional rainfall throughout the day that affected what our forecasted numbers were,” said Brissie. “Once those numbers were revised, we communicated that to local emergency services to notify the public with any means they see necessary.
A spokesperson for Mecklenburg County Emergency Management gave WBTV the time line of when and how the county alerted residents.
