<br />Flow Relationships to Non-consumptive <br />Attributes (cont.) <br /> <br />· Base flows for native species <br />- Examples of functions they provide <br />. Provide conditions for benthic invertebrate production <br />. Provide conditions for feeding and growth of fish <br />. Provide sufficient over winter habitat <br />. Secondary benefit -provide suitable conditions for <br />wade fishing <br />- Primary determination based on habitat or <br />wetted area analysis that supports native and <br />desired non-native fish and also includes <br />benthic invertebrates <br /> <br />Assessing Flow Needs: Quantification <br />Approach and Methods <br /> <br />. Quantification by stream class based on overall ecosystem function <br />(ELOHA) <br />. Strengths: <br />- Relatively rapid <br />- Broad coverage <br />- I ncorporates diverse expert opinion <br />. Weaknesses <br />- Natural daily flows are necessary, but may not be available <br />- Lacks site specificity <br /> <br />31 <br /> <br />32 <br /> <br />16 <br />
