The levels at Rutland Water have returned to normal following one of the wettest years on record but caution is still being advised.
Water company Anglian Water, which manages and maintains the reservoir, imposed a hosepipe ban last spring because of concerns the firm and the Environment Agency had over water stocks and the prospect of a drought.
The ban was lifted in June following heavy rainfall in April, May and June.
Anglian Water said 2012 had been the second wettest year for the Anglian region during the last 114 years.
The Met Office said the total rainfall in the UK during 2012 was 1,330.7mm, which was just 6.6mm short of the record set in 2000.
Anglian Water spokesman John Clare said the firm was “happy” with the levels at Rutland Water.
He said: “The stocks are very healthy and Rutland Water is well over 90 per cent full for obvious reasons.
“We are very happy with the situation.”
Overall, its reservoir levels are 87 per cent full and groundwater levels are above average.
But customers are advised to be “water wise” whatever the weather.
Anglian Water supplies water in Stamford, Bourne and the Deepings, the east of Rutland and Northamptonshire.
It was a similar picture for Severn Trent Water, which supplies water to the remainder of Rutland.
Its current water storage levels are at 96.6 per cent of their total capacity.
Severn Trent Water did not impose a hosepipe ban in the spring but advised its customers to be sensible.
The wet weather was not good news for everyone and there was a substantial amount of flooding in November, including The Meadows in Stamford.
