Lake Haupiri

Lake Haupiri is a small lake located inland from Nelson Creek, north of Greymouth. It is a popular place for trout fishing and boating. Lake Haupiri has, on its southern side, a significant community, and substantial dairy farming.

Lake Haupiri is a riverine lake. The main inflows to the lake are on the south and west sides. The main outflow of the lake is to the Haupiri River. The catchment surrounding Lake Haupiri consists of native forest, dairy farming, scrub, tussock and wetlands. Lake Haupiri’s maximum depth is 20 m. The West Coast Regional Council monitors one site on the lake, six times every year. One tributary on the south side of the lake (Heaphy Stream) is also monitored in conjunction with central lake sampling.

Scientific data for this lake

This dashboard shows information on the data collected by the regional councils and unitary authorities for two indicators of lake water quality and ecological condition: TLI (Trophic Level Index) and LakeSPI (Lake Submerged Plant Indicators). Select an indicator to see the historical results.

Water Quality

Trophic Level Index (TLI)

The TLI score is an indicator of lake health and is determined from a suite of water quality measurements.

Trophic Level Index (TLI) history for this lake

The TLI score for a lake is calculated from four water quality measurements – chlorophyll a, total nitrogen, total phosphorus and water clarity. If water clarity is unavailable, TLI is calculated using the other three water quality measurements. A higher score indicates poorer water quality.

Very good water quality. Trophic Level Index of 0-2. Microtrophic lake conditions.

Good water quality. Trophic Level Index of 2-3. Oligotrophic lake conditions.

Average water quality. Trophic Level Index of 3-4. Mesotrophic lake conditions.

Poor water quality. Trophic Level Index of 4-5. Eutrophic lake conditions.

Ecological Conditions

Lake Submerged Plant Indicators (LakeSPI)

The LakeSPI status describes the ecological condition of the lake and is based on plants present.

LakeSPI history for this lake

LakeSPI (Lake Submerged Plant Indicators) is a method of characterising the ecological condition of lakes based on the composition of native and invasive plants growing in them. A higher LakeSPI percentage result is associated with better ecological health:

LakeSPI	N/A
LakeSPI	{{spiData.details.Value}}%

The overall LakeSPI score is calculated using a Native Condition Index ('good' plants) and an Invasive Impact Index (introduced, non-native plants):

Native Condition	N/A
Native Condition	{{spiData.details.NativeIndex}}%

Invasive Impact	N/A
Invasive Impact	{{spiData.details.InvasiveIndex}}%	NA

A higher Native Condition value indicates better ecological condition, but a higher Invasive Impact value indicates invasive plants are negatively impacting native plant communities.
