Caseys Creek - Baseline Water and Sediment Quality 2017
Caseys Creek is one of a number of small spring-fed streams in the Blenheim area. It has a relatively small surface catchment, but receives water through emerging
groundwater and several stormwater discharges from residential areas located along both sites of the waterway. Stormwater discharges are predominantly affecting the water quality of the lower reaches, while the upper reaches of Caseys Creek are more influenced by the surrounding agricultural and horticultural land use.
The stream has been significantly modified over the years. Most notably, the stream channel has been straightened for almost the entire length of the waterway.
In 2017 a study of water quality was carried out to provide a baseline to allow assessment of changes to water as a result of planned residential development in the upper reaches of Caseys Creek.
