It would seem that Hillingdon Council is saying two rather contradictory things here.
"However, levels will fall or rise subject to differing weather conditions (ice, snow, continuous rain and drought).
The snow and ice at the beginning of 2010 created an increase in water levels at the site which was managed by a daily release of water as and when the weather conditions allowed.
Whilst the water was being managed at this ‘higher’ level ... The Council agreed not to release any further water from March 2010 on the understanding that levels would be assessed and weather conditions monitored daily to ensure that any risk could be identified quickly and dealt with efficiently."
On one hand, they appear to be saying that the water levels were exceptionally high in the first part of the year because of the severe weather, and that water could only be released if the weather allowed.
And on the other, that it is safe to leave the levels high because the risk could be dealt with efficiently if the weather deteriorated.
It would also appear that LBH are admitting that there is a risk from maintaining the water at higher levels.
Mr Ingle states that "The water level is currently maintained at around 0.65m below datum." However, the attached figures show that the recorded water levels were higher than this for the entire year of 2010.
In December 2010 the Uxbridge Gazette published the following article about the flood risks

Cllr Ray Puddifoot, leader of Hillingdon Council, states that the water level was being maintained at 0.6 metres below the spillway. However, this is proved to be incorrect by LBH's own figures. Also incorrect therefore is his assertion that there would have to be a 'Noah's ark event' for there to be a flood, when in actual fact, the reservoir was close to capacity for most of the first half of that year.
