That stream-specific site is wonderful. Looks like French Hill Brook is quite healthy (at least by central NJ standards). Sadly, my stream, Big Bear Brook, is most often rated as moderately impaired. On a good day we find many scuds and hydropsychidae, and a few leeches, asian clams, midges and the occasional riffle beetle. We work in a program called StreamWatch. We do our next sample in mid July. Maybe I'll take you up on the bug ID offer. Thanks.
