Digitized edition from print [produced by Environment and Climate Change Canada]. Includes bibliographical references (page 19). "A monitoring program was conducted in May 1988 to establish the baseline conditions of sediment quality in Johnson Creek which is adjacent to a proposed lead/zinc/silver mine. Sediments in Homestake Creek, an adjacent drainage, were found to be high in metal content. The high metal levels are likely a result of previous mine activity in the drainage. The sediment results are discussed in the context of trend monitoring considerations"--Abstract, page i.
