Determine how selenium concentrations are affected by dam operations. <br />IN 2.lb Determine/quantify the dynamics of major cations, anions and <br />nitrate/phosphate ratios resulting from dam operations. <br />IN 2.2 Evaluate feasibility of short term or long term changes of water temperature <br />through selective withdrawal, <br /> <br />Several activities are currently being conducted to address these information needs. <br />These include the flow release information collected at GCD by the Bureau of Reclamation; <br />the Bureau of Reclamation selective withdrawal study efforts; and the GCMRC <br />comprehensive water quality program that studies the effects of water quality on <br /> <br />November 5, 1998 <br />Second Draft - Do Not Cite, Pbotocopy, or DistrIbute <br /> <br />----------1 <br />: <br />! <br /> <br />107 <br /> <br />, <br />-' <br /> <br />~, <br /> <br />, <br /> <br />,. <br /> <br />" <br /> <br />~.' <br /> <br />,;. <br />'" <br />~ : <br /> <br />>, <br /> <br />(~ <br />r"' <br />:" <br />. <br />" <br />It <br />i: <br />( <br />:~ <br />~ <br />'" <br /> <br />,.' <br />.- <br /> <br />.'l". <br /> <br />t~7 <br />i} <br /> <br />,', <br />f~ <br /> <br />",: <br />,'.. <br /> <br />~~. <br /> <br />~., <br />\. <br />R <br />" <br />-;:1 <br />y~' <br />'.~ <br />,"' <br />~~ <br /> <br />i <br />... <br />'-":: <br />,:$' <br />roo, <br />
