<br />11 Impacts represent changes from the
<br />absolute values.
<br />21 Conditions expected in the future without additional Federal development of the Bonneville Unit.
<br />31 RecOllllended plan.
<br />41 Existing conditions.
<br />51 A zero indicate8 no change.
<br />61 All temporarily disturbed landscape would be rehabilitated to the extent practical.
<br />71 Habitat units is a combined measure of quantity and quality of habitat.
<br />81 Not affected by any project alternative.
<br />91 The values given for the Fifth Water Pumped Storage, Sixth Water Flow Through, and Sixth Water PUlllped Storage Alternatives
<br />are for Diamond Fork iDmediately below Monks Hollow Reservoir. The values given for the 1964 Dl'R Altemative are for Sixth Water
<br />Creek iDmediately below Sixth Water Reservoir and DiaIIIond Fork below Three Forks. For the No Power Altemstivs, the values given are
<br />at Syar Tunnel outlet. In addition, the values given apply to both conditions of water withdrawal frOlll the enlarged Strawberry res-
<br />ervoir.
<br />J!21 Average. monthly tempe.ratu:re in August.
<br />111 Average of spot measurements taken throughout the yea:r.
<br />121 Oiasolved oxygen levels would be slf.&htly lower at times than -lMder the recOlDlllended plan.
<br />TII A significant reduction in turbidity and sediment transport would result because project reservoirs would act as aediment
<br />traps-:- and existing i:rrigation flows would be placed in a closed system and would no longer carry a large historical aediment load.
<br />141 A slf.&htly adverse impact over existing conditiona would result frOlll high surging flows i6 Diamond Fork between Dyne
<br />powerPlant and Hayes Reservoir.
<br />151 Temperature ranges 'given are predicted to occu:r when cold water ia withdrawn frOlll the enlarged Strawbe:r:ry Re.ervoi:r.
<br />When -;arm water is withdrawn, expected temperature rangea would be 170 to 19" C for each reservoir under each alternative.
<br />161 First number represents water fluctuation under projected initial operating conditions, whereaa nUlllber in parentheaes
<br />represents fluctuation under maximUlll conditions.
<br />171 Total nUlllber of direct and indirect jobs (in person-years) from project construction.
<br />TIfI Population influx during peak construction year.
<br />191 Animal unit Months.
<br />201 Ratings prepsred by the Forest Service.
<br />2f1 Recreation-days (net annual use and increase expected in 1992).
<br />221 A net 10S8 of developed recreation uae and an unidentifiab).e net loss of disbursed recreation use would result with
<br />this aIternative. Further surveys would be required to identify specific disbursed recreation loases.
<br />11/ Available data indicate that with current Rec18lll8-tion design and construction practicea, the proposed features _y
<br />be safely built and operated.
