Nearly one accident a day is being recorded since the pool was opened to the public sparking claims that children at being put at risk.
The Drift Park pool opened 68 days ago and 64 incidents have been reported to Debighshire County Council, ranging from minor bumps to more serious accidents.
Cllr Joan Butterfield who represents Rhyl West, said the number of accidents recorded was high.
She said: "If they have had been slips and spills then it sounds like a reflection on the finish of the pool. We need to know if there are problems as we should not put our children at risk."
Fellow ward councillor Ian Armstrong stressed the pool was safe and fully attended by staff.
He said: "Kids run around all the time and accidents do happen."
The pool closed last week following an incident of vandalism which left a sharp edge and an inch thick hole across the floor of the popular attraction.
A county council spokeswoman said: "These figures equate to less than one incident a day and are considered low, especially in light of the fact that there can be anywhere in the region of 500 visitors to the pool a day.
"When the Drift Park was being refurbished, Denbighshire County Council and Leisure Services decided to run a manned pool with full lifeguard cover unlike other open air paddling pools such as Craig y Don, Llandudno, for which there will be no data on the number of incidents which have occurred there."
