Monitoring the lake’s suitability for swimming (contact recreation)
Can we swim in Lake Hayes?
Lake Hayes is monitored during the summer months, with information published on the LAWA (Land, Air, Water Aotearoa) website.
To check if the lake is safe for swimming, the levels of the bacteria E. coli are measured.
This graph shows the overall risk grades for the last three summers - 2015/16, 2016/17 and 2017/18.
Two new monitoring sites for 18/19 season
We think the E. coli monitoring site may be too close to the resident duck population, which is skewing the test results.
We also know this is a popular spot for tourists to feed the ducks.
This means that the very high E. coli readings in the summer of 2018 are not likely to be representative of bacterial count in the whole lake.
This is why we’re installing two more E. coli monitoring sites at other points in Lake Hayes.
