In March 2009, Gorge Road School pupils had the chance to explore what lives in the streams of the Waituna Catchment. The main purpose was to see where koura were living, as they are a good indication of stream health.

Of the four sites that were checked out by the school, two of them had koura.

Both these sites were ones that had little modification.

At the Moffat Stream on Moffat Rd, kokopu were caught in the minnow traps and at the Waituna Stream site at Pirie's on the Kapuka North Rd, there was a banded kokopu and an inanga (the main whitebait species) caught.
