Habitat

It has been raining steady and heavily for 3-4 weeks on and off. The water levels are high and the creek width is wider, to the point that it was difficult to measure both the depth and width accurately. The creek bank is very soft and unstable, to the point that it was unsafe and too difficult to gather enough macro-invertebrates to give an accurate ready of abundance and bug score. We found a few sensative species, a couple of water boatman and no tolerant species at all.
