observed at the top of the weir. There were elevated flows at the time of the inspection due to heavy rainfall previously. The lamprey baffle was viewed during the inspection on 4 October 2023 as the flow in the river was lower than the previous inspection. It was noted that no rocks had been installed above the lamprey baffle to further reduce flow, but this was no longer needed as the required timeframe for lamprey passage (1st June to 30th September) had passed. Tree debris was observed

samples were collected for analysis. One abatement notice was issued in relation to untreated silt and sediment discharges leaving the site due to heavy rainfall inundating the capacity of the silt and sediment controls. Four samples were obtained and analysed in conjunction with this incident. Follow up inspections found the abatement notice had been adhered to. These discharges were deemed unlikely to have any significant adverse effect on receiving waters as discharges were temporary in

Pollution minimisation The Taranaki Regional Council recommends the following service station requirements as best management practices. Check this information when operating your service station and when establishing or upgrading daily site operational procedures. If all of the items on the list are fully addressed then the potential for
Douglas fir
especially in the South Island. On favourable higher altitude sites, Douglas-fir exhibits a significant growth advantage over other species. A high proportion of the tree’s wood is heartwood, which is non-durable in ground contact. Consequently, it is most commonly used for structural purposes in engineering and construction. Siting Douglas-fir grows well over most of the country in areas which receive moderately high rainfall (1000 to 1500mm annually). Growth is generally best on moist,
