Frankton Bay and Lake Hayes - contact recreation results
Frankton Bay – Lake
Wakatipu
Otago Regional
Council (ORC) water quality samples taken from Frankton Bay
at Lake Wakatipu have returned a reduced level of the
bacteria E. coli. Results from the sample on Monday 26
February shows 16 E. coli/100 ml. This result means that
Frankton Bay is once again suitable for swimming and contact
recreation. This is a significant reduction from the
previous week’s result, which showed E. coli levels at
921/100 ml. Swim warning signage will be removed from
Frankton Bay today.
Government water quality
guidelines for recreational swimming areas are that those
with less than 260 E. coli/100 ml should be safe, whereas
water with more than 550 E. coli/100 ml indicates a
potential health risk. The cause of last week’s high
E.coli level is still under investigation
Lake Hayes
Following two successive weeks where
cyanobacteria levels have reduced, swim warning signage will
be removed from Lake Hayes today. On Monday 19 February, the
level of cyanobacteria had reduced to a biovolume of 1.32
mm3/L, down from an initial reading the previous week of
3.96 mm3/L. This week, on Monday 26 February, test results
show that cyanobacteria levels had reduced again to a
biovolume of 1.05 mm3/L. Lake Hayes will continue to be
monitored for cyanobacteria on a weekly basis.
ORC would like to remind people recreating in or around Lake Hayes to familiarise themselves with cyanobacteria, and know what to look for before going for a swim or exercising your dog in or around the Lake.
