Information used in this indicator has been compiled from surface water resource consents and estimates of permitted surface water takes in the Waikato region. Check out our map showing the density and distribution of consented surface water takes in our region.
Waikato Regional Council estimated the number of permitted users with a model requiring information on both the number of people and animals in each surface water catchment. Check out the methodology of the model for calculating the ‘permitted’ water use as described for surface water catchments in Technical Report 2007/47.
Data for this indicator were collected from surface water resource consents and estimates of permitted surface water takes up to 2015.
The amount of surface water available for use from a waterway is set in the Regional Plan in Table 3-5. The location of the assessed waterways can be seen here on the water allocation maps.
We compare a waterways’ amount of ‘available’ surface water with the amount allocated in summer and winter (the maximum that can be used by consented offset by any returned water and permitted takes). From this we can estimate the level of stress surface water resources are under and how it varies from winter to summer.
We divide monitored surface water resources in our region into three categories of ‘stress’:
This provides us with a guideline to identify potential problem areas which may need more intensive monitoring. Most of the monitored surface water areas in our region are under medium to high stress in summer and low stress in winter.
