Abstract or Summary
  • "The project objectives were to determine the possibility of raising the subterranean water in adequate amounts by installation of an underground weir; to determine what type of structure would be most feasible; and to formulate a biological evaluation program if the first two objectives were accomplished. Tex Creek, tributary to Murderers Creek which flows into the South Fork John Day River, was chosen as the study stream because of its history of steelhead use and loss of young due to intermittent flow in slimmer months. The Tex Creek study was designed to test subterranean structures that might raise and direct subsurface water into the stream channel to prevent intermittent summer flow...The all-plastic structures which extended across the valley floor were effective in raising subsurface water, while the shorter barriers located across the stream channel only were not...A trap was operated at the mouth of the stream to record upstream and downstream migrant fish. Observations indicated that the majority of adult steelhead arrive in Tex Creek during May." (Abstract from Authors)
