Water quality, chemistry and streamflow were analyzed in 1911/1912 and a chart showing measurements is included. “A dense growth of timber covering most of the drainage basin serves to retard surface erosion and to lessen the force of the floods. The gradient of the stream is steep, and fluctuations in stage are sudden and large, rises of a foot an hour for twelve or more hours being not uncommon.” (p.48) ER -
