The water that flows through the narrows of site five works its way around a small peninsula of soil and rock which supports an abundance of grasses.
Water collects in a large, deep, stagnant pool.
The pool appears to have been established by erosion that occurs during the heavy runoff of winter. A very steep undercut bank on the north side provides evidence of the pools origin. The depth of the pool is usually greater than 1m. DO levels tend to be low here which creates a low diversity of organisms. The path around site six and seven opens up into a large deposit of gravel offereing students excellent access to the water.
