Depending on your "definition" of "high flow volume"... back in 1986, when Fantail was actively discharging rather great volumes of water, we looked for and could see absolutely no change in activity or discharge by such nearby (yes, across the river, but very near) features as Hillside and Seismic, nor in the nearby springs on the Fantail side of the river. I'm sure there are other examples. Scott Bryan In a message dated 9/28/2010 5:02:14 P.M.
