CHAFFEY Dam has risen to its highest total this year thanks to last week's snow and rainfall above Nundle.
On Wednesday, it was revealed the dam finally cracked the 15 per cent mark this week for the first time in 2020.
The main water supply for Tamworth has risen by more than half a per cent capacity in the past week, according to new figures from Tamworth Regional Council.
In the 24 hours to July 1, almost 40 megalitres - or 16 Olympic swimming pools worth - of water flowed into the dam from the Peel River, according to data from Water NSW.
Council's weekly water report showed an average of 11.64 megalitres was released from Chaffey Dam per day. This figure includes water gushing down the pipeline to Tamworth's water treatment plant.
In the past seven days, Tamworth residents smashed the Level 5 target water consumption of 16.1 megalitres a day, thanks to the cooler weather.
Locals used an average of just less than 14.8 megalitres of water per day.
Dungowan Dam also had a surge in capacity over the past week, rising more than five per cent to reach 67.4 per cent capacity.
The dam is owned by Tamworth Regional Council and is the city's back up water supply.
Split Rock Dam had a small drop in water level. But even at 4.6 per cent capacity, the huge dam holds enough water for the townships of Barraba and Manilla, which are both on the minimum 'permanent water conservation measures'.
All villages and towns in the Tamworth local government area are on this base level except for Tamworth, Moonbi and Kootingal.
Chaffey Dam had been hovering around 13 to 14 per cent full in recent months, despite widespread rainfall in the Tamworth region during the first half of this year.
Although the rise is a promising milestone for the often dwindling dam, it's not enough to become complacent with water restrictions.
Tamworth is still on the highest Level 5 water restrictions, along with Moonbi and Kootingal.
It is understood that won't change until the water supply climbs all the way to 25 per cent full.
Even then, the city will only drop to Level 4 restrictions. Restrictions will go down another level with each additional 5 per cent gained after reaching 25 per cent.
