A Baseline Biological Study of Upper Silver Creek  by J.S Griffith, F.L Rose, G.W. Minshall and C.Y. Faler 1982

In October of 1981, the fish population of the TNC portion of Silver Creek was sampled to assess its status and especially evaluate changes that may have occurred since the implementation of catch-and-release regulations in 1077. Since size and depth of the stream necessitates elaborate efforts to quantitatively estimate fish abundance, the researchers instead collected trout from throughout the upper stream system to evaluate growth, condition and hook scarring.  . . . describes results..
