<br />.'~ r' I . _ <br />I..U I / <br /> <br />" <br /> <br />The microscope slide artificial substrate samplers were used to collect <br />algal samples. At both stations the clearly dominant alga was <br />Navicula sp., which constituted 71 and 94 percent of the algae observed <br />at the Masters and Ft. Morgan sites respectively. Among the other <br />common diatoms at the Masters site were Synedra sp., Cyc10te11a sp., <br />and Diatoma sp., along with the green alga U10thrix sp. The only other <br />relatively common alga at the Ft. Morgan site was Dip10nia smithii. <br />The SOl's for the slides at the Masters station ranged from 1.0 to <br />2.2. At the downstream site the range was between 0.2 and 1.8. <br /> <br />The low SOl's obtained from both the macroinvertebrate and the algal <br />samples are indicative of an enriched, i.e. eutrophic condition. Although <br />the actual number of organisms collected in the samples was relatively <br />low, an SOl of less than three is usua11~ considered indicative of a <br />trend toward such enrichment (Otto, 1974). This fully confirms the <br />results of the algal assays.' <br /> <br />Suitability of Reservoir for Recreation and Fishery <br /> <br />The following factors were considered in appralslng the probability of <br />primary body contact sports with respect to bacteriological conditions: <br />(1) the water CJJa1ity meets the proposed State standards for primary <br />contact sports, (2) the only current standard not met during the <br />recreation season is the fecal streptococcus standard. However, there <br />are indications that the fecal streptococci that are present are not <br />of human or domestic origin and therefore, may be of little sanitary <br />significance. This would have to be verified with a sanitary survey. <br />On the basis of the above, it appears the factors favoring the future <br />suitability of the reservoir for primary contact recreation outweigh <br />those that would prevent its development. Primary contact recreation <br />development should be retained in the plan. <br /> <br />The results of the temperature simulation indicate that the reservoir <br />would support a warmwater fishery. They also show that a put-and-take <br />co1dwater tailwater fishery could usually be maintained for about 10 <br />months of the year. In some years there could be some oversummer <br />survival of co1dwater fishes in such a tai1water fishery. <br /> <br />23 <br />
