Water levels at Llandegfedd could be too low for safe launching of boats for the PAC's privileged access event on the water, on October 21.
Special events organiser Mark Skinner is liaising with water officials in the run-up to the event.
"They say the reservoir is really low and the problem is launching boats from the pontoon," Mark said.
"If there's enough rain to get the boats off the pontoon we'll be fine. It all depends how much rain they get in South Wales."
Mark added if the event is cancelled applicants will be given the option of fishing a different day - subject to this being arranged - or having their money returned.
