Abstract

Nehru Focus Catchment is located in the upper reaches of the Arrowsmith Catchment. It is roughly bounded by Sunset Road in the north, the north-south Kadathinni Hills to the east, the Three Springs - Eneabba Road to the south and Reed Road in the west. It changes in elevation from 372 metres Australian Height Datum (AHD) at roughly the intersection of Nehru Rd the Kadathinni Hills to the east and 220 metres AHD near the outlet of the catchment into the Arrowsmith River.

The total area of the catchment is just over 7,400 hectares.

One of the prime areas of focus identified in the catchment was the extensive area of salinity developed in the valley floor. Salinity has occurred in the Upper Arrowsmith since the 1960's. An area south of Hydraulic Road exhibits the most obvious area of salinity. Farmers' comments suggest that the area was always moderately damp, but was originally crop, (there was evidence of working lines in the area). However, since the early 1960's, (which were reasonably wet) the area has been seasonally wet and has become too saline for cropping.
