According to Water NSW, Keepit Dam is now at six per cent capacity after a weekend of rain. It's risen by 3 per cent in just a week.

This is also 20 times higher than the level was at Christmas time in 2019, when it was at 0.3 per cent.

Lake Keepit park manager Leith Smith said visitor numbers had "easily doubled" over the weekend, with people enjoying more water-based activities.

"We saw a lot of boats come out ... and all the good fun stuff. With the water up at that percentage, there's enough room for water skiing, fishing and that sort of thing," Mr Smith said.

Lake Keepit Sailing Club vice-commodore Ian Pine is pleased with the higher level, but said the club was aiming to reach the 10 per cent mark.

"At the current level the water is fairly flat which means it spreads out over shallow water, and we have to make sure we don't get too exuberant and go into shallow water," Mr Pine said.

"The 10 per cent level is what we need to get to say things are back on track."

Mr Pine said if they did reach this level, it would mean the club would be able to lock-in upcoming events like the Keepit Kool Regatta, which had to be held at Copeton Dam last year due to low water levels.

"We're hopeful there'll be more inflow but we have to be realistic that we may have to plan to take the regatta away again," he said.

"But this year, with close to 6 per cent and hopefully just a tiny bit more rain, it gives us the confidence to plan the regatta and hold it at Keepit."

The vice-commodore confirmed that the three-day school holiday sailing camp in April would be going ahead with the water at six per cent.

"[Last year] we customised it to the water we had available, [but] now this will give us so much more scope and the different boats will have a bit more room ... and that'll make it more fun for everybody," he said.
