Inglis River

While not tributaries of the main river system, Sisters Creek and Seabrook Creek are notable minor creeks which form part of the Inglis-Flowerdale catchment area. Annual rainfall ranges from about at the coast to greater than in the upper reaches of the catchment, some inland from Wynyard. Forestry plantations dominate the landscape in the western region of the catchment, with intensive agriculture land-use in the north and eastern regions. Because of the steep and confining nature of the topography around the Inglis and Flowerdale rivers, both have retained substantial native forests that tend to buffer the rivers from both land-use activities. ==Environment and wildlife==

A 2003 water assessment report determined that the upper Inglis and Flowerdale Rivers and their tributaries are in generally good ecological health, however the middle and lower reaches of the Inglis River have less healthy macroinvertebrate communities. The poorer health of these communities suggest that they have been impacted by sedimentation from upstream forestry operations, gravel pits and poor stream-side agricultural land management practices. Measures to help mitigate further environment issues may include fencing off rivers to prevent livestock from accessing waterways and re-vegetation of river banks to prevent further erosion. Other aquatic threatened species in the Inglis-Flowerdale catchment includes the endangered giant freshwater crayfish, and the Australian grayling. Poor remediation processes at the time, which involved removing the roots of the trees, has led to significant soil erosion and remains to be an issue for local agricultural landholders – more than a decade later. ==See also==
