Although oxygen levels can be critical for aquatic life, experience <br />with similar streams inditates that more than adequate levels of dis- <br />solved oxygen are found yearlong in the Encampment. Levels will remain <br />near or even above saturation levels, somewhere around 9.0 - 10.0 mg/l. <br />'The lower limit for trout ~roduction is 6.0 mg/l. <br /> <br />. d. Other Chemical Parameters <br /> <br />Table 2 is a summary of six chemical analyses, over a two year period, <br />for a number of locations ih the Upper Encampment drainage. Th~ data <br />indicates low concentrations of all constituents - well within existing <br />'drinking water standards. <br /> <br />V. BACTERIOLOGICAL PARAMETERS <br /> <br />Existing bacteriological data is very 1 imited and inconclusive. <br />The data, and the low level of impacts in the drainage, suggest that <br />it easily meets the Colorado State Standards for Class BI Fisheries. <br />In addition, it meets established Public Water Supply standards; i.e. <br />it is sui tab 1e for public \Ia tel' supply if treated. Based on exper- <br />ience with similar streams, backgl"ound ("natural) bacteria levels are <br />probably high enough to exceed safe levels for drinking without treat- <br />ment. Livestock grazing probably increases the bacteria levels during <br />low flow periOdS qf the summer, There are likely n0 measurable indi- <br />cations of human i-mpact on the hacteria levels, since human use is <br />limited to occassional hiket's and fishermen. <br /> <br />....'.NJ ",',,',' :>,' '. . . <br />~1i{~~J1 .,:fi',~,<~~ 'i .'. , <br />~t:~/~:~:~/,:/. : <br /> <br />('1'\11") "I" , <br />,.",''-' .:. <br /> <br />.
