<br />18 <br /> <br />CLARKSON ET AL. <br /> <br />Because year cIass strength of the larger native fishes likely was variable in response to <br />historical pre-dam environmental conditions, operations under this new scenario would not <br />necessariIy have to optimize conditions in all years. Opportunities wouId exist in some years <br />to adjust operations specificalIy to suppress non-native fishes (e.g., flushing flood flows, <br />temperature changes to preclude reproduction, etc.), benefit other natural resources, or for <br />other purposes. As bioIogical information becomes more reliable and species responses more <br />predictabIe, the system shouId be fine-tuned to sustain both natural and human resource <br />demands. While the time frame to compIete this process will be protracted, we believe the <br />stated goals and objectives are realistic and can be successfully attained. <br /> <br />Literature Cited <br /> <br />Andrews, E.
