| Contents Notes | Sediment content of spawning areas in 108 Creek increased over a 6-year period as logging progressed in the watershed but did not change appreciably in the following 3 years as cutting shifted away from the main stream. Marked changes in sediment content of Kadashan Creek spawning areas also occurred although logging has not yet begun. The geological, hydrological and biological characteristics of the two streams differ widely. The effects of sediment content changes upon the production of pink salmon fry in the two streams can't be effectively separated from the effects or other environmental variables. An analysis of the relationship between fine sediment and intra-gravel oxygen in the two streams was inconclusive. |
