Nelson has entered tougher stage 4 water restrictions.
Even with recent rain, discharge levels which feed the reservoir are low.
A dry summer and a fall forecast of 60% of regular rainfall are all contributors to the stricter rules.
Colin Innes, Director of Public Works outlines some of the stage 4 protocol.
More sustained rain is required as recent gains could disappear within 2 weeks.
Innes says residential water consumption was down about a third compared to July but there is still stress on the system.
