The outcomes of what Nolan refers to are published in the ASTM Standard Methods. These will be under effluent testing, 48 hr, 24 hr, etc acute and chronic tox assays using daphnae, chironomids, etc. There are other effluent testing protocols for testing impairment, most are standard methods under

Took a course one time taught by John Cairns, Ph.D. of VA Tech at the U. of Michigan. His entire push was to use macroinvertebrates, etc. as more important tools of monitoring Water Quality in not only Streams, Rivers, but also Lakes. So, find publications from him. I'm sure in all of the indic

The closest thing you are going to get is the following: Oligotrophic lake eutrophic lake hypereutrophic lake There are a ton of "intermediate" states. Also, categories like marl ponds, peat bogs, fens.. many to most of these are defined on the very things you question. However, the idea of i

Its also really depend on the nature of you question. "good" "fair" or "poor" for human consumption criteria (you can use EPA guidelines for this propose) or "good" "fair" or "poor" for environmental assessments. It takes years if not decades for lakes to respond to anthropogenic/natural alteration
