Book excerpt: BPA proposes to fund the construction of a fish passage improvement project on Bear Creek in Grant County, Oregon with the Oregon Department of Fish and Wildlife. Bear Creek enters the mainstem John Day River at river mile 258.5. At stream mile 0.3 Bear Creek crosses an irrigation diversion, entering Hall Ditch. At times Bear Creek is completely diverted into Hall Ditch. A second diversion from Bear Creek is located 200 feet below the area where Hall Ditch and Bear Creek intercept. As a result of these two diversions, in late summer Bear Creek is essentially dry at the project site. In addition, the diversions are fish barriers at low flow. The objectives for the proposed project include the following: prevent flow from Bear Creek (a Clean Water Act Section 303(d) listed stream for temperature) from mixing with Hall Ditch water; prevent fish from leaving Bear Creek and entering Hall Ditch; ensure fish passage at the project site; and upgrade an existing fish screen to National Marine Fisheries Service's (NMFS) fish screen standards. A number of measures will be implemented to meet these project objectives. The proposed action would prevent mixing of Bear Creek and Hall Ditch waters, and prevent fish from entering Hall Ditch by siphoning (siphon bypass) Hall Ditch under Bear Creek. The proposed project will remove existing, older diversions and plug up the screened irrigation canal currently used by the landowner. The existing diversion structures will be replaced with a fish-friendly diversion. In addition, a NMFS-approved fish screen and a water meter will be installed in the abandoned canal to allow fish passage and monitor water withdrawal by the landowner.
