The purpose of the study was to obtain baseline data on water, sediment and biological conditions for use as comparison standards when evaluating future mining development in the area. The water and sediment chemistry in the lower reaches of Cache Creek reflect the characteristics of and appear to be influenced by groundwater drainage from mineralized areas. The quality criteria of the water downstream from the mixing zone of Cache Creek on the Ketza River shows no impact on the environment"--Abstract, page i. |
