Zone Name:	Mayfield - Hinds	Current Status:	(Yellow)
Allocation Limit:	148 million m3/yr	Valid date:	23 June 2007
Approach:	50% land-based recharge

Recharge component

Method of estimation

Background notes

The Mayfield-Hinds area benefits from the border dyke irrigation scheme, where extra water is applied from a surface water source. Some wells around SH1 have become more or less reliant on the recharge caused by this scheme.

New applications to take groundwater that is linked to a surface waterway may be subject to surface water restriction and/or allocations.
