Drought Restriction map
The map links Postal Sectors (based on centre point location) to Water Resource Zones 2025 (WRZs) and MOSL Drought Restriction levels which consider the Water Company drought level, specified by wholesalers by WRZ and the EA Drought Level status, taken from the latest EA dry weather and drought briefing. Each MOSL Drought Restriction level provides a view of the water demand request to customers (i.e. voluntary reductions, temporary use bans, non-essential use bans or Emergency Drought orders) and also the wider context to these requests. Reasons for demand reduction requests are aligned with both the Water Company drought levels and the EA’s view of previous rainfall ie prolonged dry weather, drought, severe drought or emergency drought, but also in some cases can relate to other considerations such as River levels in sensitive catchments. Details on how the MOSL Drought Restriction levels align to the Water Company Drought Levels and the EA Drought Levels are provided in the table below the map. This map aligns with data provided on the Drought Restriction dashboard.
