Abstract
The fourth of seven educational learning modules for the IDAH2O Master Water Stewards citizen-science water-quality monitoring program focuses on habitat assessment, which is conducted only once a year, at times of low flow, like August or September. Learn about high and low flows and how either affects a stream's structure and habitat, a bank's visibility and the accessibility of rocks or other substrates in the bottom of a stream. By module 4's end, you'll have produced descriptions that will be valid for a year.
