Data such as daily rainfall, regional reservoir stocks, river levels and demand is monitored and you can see our current position against historical and seasonal trends and fluctuations.
The majority of the figures are produced either as a % of total capacity (in the case of reservoir stocks) or as Ml/d which is megalitres per day. 1 megalitre is equivalent to 1 million litres.
Here's a summary of the Watsit report data:

| Notes | % Rainfall (provisional) this month across the Yorkshire region compared to long term average | Reservoir stocks this week vs last week | Key river levels across our region | Regional demand in megalitres a day |
