<br />I <br />I <br />I <br /> <br />averaged 3103 acre feet for the ten most recent years of <br />diversion. Records more than 5 years prior to the beginning <br />of the study period are not locally available from the <br />Division of Water Resources. Snow survey records, however, <br />indicate that the long term average would be slightly higher, <br />so for the reconstruction loan repayment period, I believe <br />that the average diversions will probably be about 5% higher <br />than the tabulated average. <br /> <br />I <br />I <br />I <br />I <br /> <br />f. Water quality. <br />(1) All project waters are diverted from either Crystal <br />Creek (formerly called' Lost Creek) or Chicken Creek, both <br />tributaries to the Mancos River. Water quality is excellent, <br />suitable for potable water supply with a minimum of <br />treatment. The water transportation system is stable and <br />non-eroding so the water normally arrives at the reservoirs <br />pure and crystal clear. . <br /> <br />I <br />I <br />I <br /> <br />(2)(3)&(4) are not applicable <br /> <br />(5) Sedimentation. As noted above, the transportation system <br />is stable and the water diverted from the tributaries is <br />normally clear. There is a sl10rt period during peak spring <br />snowmelt when the water becomes cloudy, but not muddy. <br />Sedimentation is so very slight that it should never pose a <br />problem to the Bauer Lakes system. <br /> <br />I <br />I <br />I <br /> <br />6.Chapter ~ Plan of Development <br />a. Physical Plan. There are no anticipated changes in the <br />physical system or in the operation of the Water Company. <br />Each reservoir has a superintendent to monitor fillings and <br />releases, inspect and report on physical aspects of both dams <br />and the delivery and measuring structures, etc. This method <br />has proven to be quite satisfactory in the past, and their <br />combined salaries of $420 per year is the best bargin around! <br /> <br />I <br /> <br />b. Geologoc investigation. The dam is founded on a stable <br />sandstone formation. The sandstone is fairly coarse grained <br />and moderately pervious. The formation is gently undulating, <br />with an overall dip of about 5 degrees to the South- <br />southwest. <br /> <br />I <br />I <br />I <br />I <br />I <br /> <br />There is a slight foundation seepage, which has been <br />collected and measured through a series of 4 vee-notch weirs. <br />The volume is extremely minimal, with the total seepage from <br />the 1850 foot length of the downstream area peaking at 0.046 <br />cfs (20 gpm) during maximum storage. It is anticipated that <br />flattening the upstream slope and mantleing the sandstone <br />infiltration bed even deeper should lessen this low volume <br />even further. <br /> <br />Since the dam will not be raised, the water surface not be <br />raised, and blanketing of the 3:1 slope should lessen what <br />little percolation that there is now, I feel that further <br />geologic investigation is unnecessary.
