<br />Benthic Invertebrates
<br />
<br />.,
<br />
<br />A systematic collection of benthic invertebrates at the stream
<br />stations was. not ul)dertaken. However, at each stream station. ben-
<br />thic organisms were collected and checked for gel)eral diversity.
<br />Stoneflies ,mayflies, caddis flies , beetles, flies, and o.ther un-
<br />identified organisms were present. These are pollution intolerant.
<br />or~anisms and indicate the Water quality is suitable for a normal
<br />benthic population. The objective of this study was to invedti-
<br />gate whether high nutrient levels were going .to be a water quality
<br />problem; nutrient levels in the range measured should not have'a
<br />deleterious effect on benthic organisms and all other water
<br />quality parameters measured were generally representative of high
<br />quality water.
<br />
<br />The only previous data collected was at the mouth of Williams
<br />Creek (see Appendix A) and showed it to be the most biologically
<br />productive str.eam sampled in. the Piedra drail)age.
