in April 2023 indicate that the scheme had had little to no effect on the communities prior to this latest sampling event. This could be attributed to the frequent rainfall during summer, as these flow conditions reduce the influence of the HEP scheme activities. This is evident in the significant improvements in the macroinvertebrate community health at the impact sites, while the control site was in average to above average health. Consequently, based on the current (and previous) survey

in the Taranaki region. The highest median enterococci count was recorded at Ohawe (40 enterococci cfu/100 ml). Median enterococci counts at all other beaches were equal to or less than 9 cfu/100 ml. Out of the 217 samples collected for both SEM and for additional monitoring purposes, 95% were below the Alert level. Of the few samples which entered the Alert and Action guideline category (5%), the vast majority (9 out of 11) had been influenced by rainfall and/or freshwater. The

likely to be contaminated. In these circumstances, sampling is to be undertaken again within 24 hours to see if the situation is continuing. If the second result is also above 280 then ‘Action’ mode is triggered. That is, it is when there are two consecutive samples above 280 enterococci per 100 ml that it is considered public health is potentially compromised. This involves notifying the Taranaki District Health Board. As discussed below, high flows in streams and rivers following rainfall
Review of the status of freshwater quality in Taranaki
periphyton proliferate. In particular, the duration of low, warm, and slow flows in the presence of strong sunlight is a controlling factor.

This
