Floodplain aggregate mining in western Oregon

Mining Engineering, 1999, Vol. 51, No. 12, pp. 6-14
Schnitzer, E.F.; Wampler, P.J.; Mamoyac, S.R.

In several cases, breaches occurred between the gravel pit and the river. Initial evaluation of several sites that experienced these breaches showed that impacts to the river system were complex and varied significantly from site to site.
