A FEW wet weeks have seen Leslie Dam's capacity rocket up to about 30%, just in time for the school holiday campers.
A spokeswoman from SunWater said the level of the dam has almost doubled since this time last month.
"This is promising for irrigation customers in the Upper Condamine region,” she said.
"If we continue to see good inflows into Leslie Dam, there is a chance Upper Condamine irrigators' announced allocation could be increased from 0% in the coming months.”
The spokeswoman said SunWater monitored weather forecasts to help predict inflows to dams.
"This information helps us gauge what inflows we may expect for our storages and to provide downstream residents and community information about predicted outflows from our dams,” she said.
"Weather forecasts are also used to help plan our infrastructure maintenance works.”
Caretaker of the Washpool campgrounds at Leslie Dam Tony Brewer said lower dam levels did have an impact on visitor numbers.
"No doubt we don't get as many visitors when the dam is low; fisherman especially, they want to see the dam full,” he said.
"It's a lot higher than it has been, and water from the recent falls is still trickling into the dam from the catchment area,” he said.
"That won't happen for much longer though, without more rain.”
Mr Brewer said the campground was at about average capacity for this time of year.
"We've got about 15 separate sites in at the moment,” he said.
"The school holiday crowds haven't really shown up yet, but I'd expect that to change over the weekend and into next week.”
Camping at the dam's edge were regulars from Ipswich, Ray and Tracey Kavanaugh.
Mrs Kavanaugh said there was a huge difference since her last visit at Easter.
"I think it was at about 12% then,” she said.
"It's probably gone up six feet since we got here a week ago.”
Connolly Dam is full and overflowing, but at only 2500 megalitres, is almost 104,000 megalitres less than the capacity of Leslie Dam.
A Southern Downs Regional Council spokesman said the dam is full and that is ideal.
"On September 8, the capacity was at 72.7% so the recent rains meant an increase in capacity of 27.3%,” he said.
"For town water services, we don't need any more rain at this moment, but we'd ideally require more rain whenever the level falls below 75%.”
