Professor Nigel Wright is a civil engineer at Nottingham Trent University.
The expert in flood management told the BBC it will take a few more days until the water is reduced to an acceptable level.
Image source, Tilly OwenHe said: "You can't let the water out of the reservoir too quickly because that can just cause flooding problems downstream.
"They're trying to get the water out of the reservoir as quickly as they can without causing further damage
"In the meantime, shoring the dam so it does not collapse."
Mr Wright said it's "unlikely" the dam will be repaired and is more likely to be replaced.
He said this long-term work shouldn't stop residents from returning home - as long as the water levels are safe.
A woman evacuated from Whaley Bridge made a video of the repair work from her mother's house, which is in an elevated spot near the dam.

RAF Wing Commander Gary lane has described the RAF's efforts to seal the breach in the dam as like building "a big Lego block".
It's a difficult task because crews need to drop the stone into centimetre square areas, he said.
They have to get as low as possible as dropping from a height could put more strain on the dam, he explained.

Lynn and Matt Lingard have been staying with a family member since coming back from a shopping trip in Stockport yesterday and being told they couldn’t return to their home.
They said they were initially told they could not retrieve their two dogs Sooty and Sweep from their house but returned to the cordon in the evening and were allowed to quickly grab them.
“I think if we’d lived any further inside the exclusion zone they wouldn’t have let us do it," Matt said.
Lynn added: “Unfortunately, we couldn’t get all out pets out. We still have two rabbits there with no food.
"We had to make a choice. They might be OK, they might not be. It’s heartbreaking.”
