Lake Kainui (Lake D)

Horsham Downs, Waikato

Lake Kainui is located within the Kainui peat bog in the Horsham Downs area. Due to its locality, the lake is highly peat-influenced, giving the water a brown/tea-coloured appearance. This lake is popular for water skiers during the summer months. An access key to the boat ramp can be obtained from Waikato District Council.

Cyanobacterial samples are also taken during the swimming season.

This site is monitored for 12 weeks over the summer period (the start of December to the end of February).

Source Information

Waikato Regional Council monitors water quality at popular swimming spots throughout the Waikato region.

Water quality data on Swim Guide is sourced from the LAWA Can I Swim Here? website. www.lawa.org.nz/swim

At this site, water is regularly tested for levels of E. coli during the summer months. This faecal indicator bacteria is used to indicate the level of harmful pathogens in the water.

See information on recreational water quality monitoring in New Zealand in the LAWA factsheet: https://www.lawa.org.nz/learn/factsheets/coastal-and-freshwater-recreation-monitoring/

Beach sites are shown as a GREEN swim icon if the latest E. coli test result was in the range of 0 - 550 E. coli / 100 mL.

Beach sites are shown as a RED swim icon if the latest test result exceeded 550 E. coli / 100 mL or if this site frequently exceeds the standard or there is a temporary water quality issue outside the routine testing programme (e.g. sewage overflow).

See information on the standards for recreational water quality monitoring in New Zealand in the 'What do the swim icons mean?' LAWA factsheet.

LAWA recommends for all sites, to avoid swimming for 2 - 3 days after significant rain, even for sites that normally have good water quality.

A good rule of thumb is to check that you can see your toes in knee deep water.
