Description:Excerpt from Attempts to Guide Small Fish With Underwater Sound One of the most uncertain and difficult problems in providing for the safe passage of migratory fish around high dams is created by the migration of the young salmon to the ocean from upstream spawning grounds. Experiments indicate that turbine and spillway hazards at one dam may cause a considerable loss of these small fish. This loss becomes of increasing concern when multiplied by each new dam under construction or proposed for the Columbia River. When this potential threat to the resource first became known, the Fish and Wildlife Service initiated studies to develop methods of providing safe downstream passage for fingerlings. Basic to the accomplishment of this objective is a knowledge of their distribution in the river. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
