Subject: Intermittent streams
Concentrations of nutrients, pesticides, and soil from agricultural runoff are
generally highest in small streams and drainage channels. In many cases such
streams flow intermittently, and remain dry between irrigation or storm events.
I'm looking for information on the ecology and regulatory status of intermittent
streams. Specifically:
(1) Do states, regions, USGS, etc. have an operational definition of
"intermittent"? For example, perhaps a stream would be classified as
intermittent if it flows less than, say, 90% of the time?
(2) Do any states, regions, agencies etc. have different designated uses for
intermittent vs. perennial streams?
(3) Are there any good reviews of the ecological significance of intermittent
streams? Are they critical habitat? What are the long-term ecological impacts of
agricultural runoff in intermittent streams?
