1 <br />' years, this water right is expected to be out of pri- <br />' ority from July to September, but in 1977 it would have <br />been out of priority from April to September. <br />The 10-acre-foot capacity pond provides for water <br />' storage during the term of permit; two ponds are anti- <br />' cipated for subsequent permit terms. Average with- <br />drawals are not expected to exceed 50,000 gpd during <br />the term of permit and are likely to be on the order of <br />15,000 gpd. <br />~ 1 <br /> <br />1 <br /> <br /> <br /> <br />1 <br />1 <br />1 <br />1 <br />1 <br /> <br />Water from the freshwater pond(s) is either treated to <br />meet potable and sanitary water requirements, used and <br />then treated as sanitary waste water, or it is with- <br />drawn for dust suppression in the mine in which case it <br />then becomes mine water. <br />Total water withdrawals from the North Fork during <br />Water Year 1983 were approximately 10 acre-feet. Most <br />of this water withdrawal occurred from late October <br />1982 to late July, 1983. Water use during the period <br />of late July through the end of the water year was from <br />water storage as the mine's water rights were out of <br />priority. Low flow in the North Fork during Water Year <br />1983 was 36 cfs on December 12 and again on February <br />15. The maximum withdrawal at the intake is 450 gpm <br />with both pumps operating. This is less than 3% of the <br />observed low flow in the river during Water Year <br />-26- <br />
