<br />SUMMARY AND RECC. E:N'DATIONS
<br />
<br />1.
<br />
<br />As Williams Creek emerges from the Wilderness, the nutrient
<br />levels increase. The only apparent source is runoff from
<br />irrigated pastures adjacent to the stream and reservoir.
<br />
<br />2.
<br />
<br />high, with phosphorous being
<br />Nitrates instead of phos-
<br />factor preventing a large
<br />nitrogen-phosphorous ratio
<br />
<br />The measured nutrient levels are
<br />the greatest individual problem.
<br />phates appear to be the limiting
<br />scale nuisance algae bloom. The
<br />.. 'is low.
<br />
<br />3.
<br />
<br />To date, nutrient enrichment has .resulted in a highly productive
<br />fishery with some nuisance aquatic vegetation .and color changes
<br />appearing during 1976. Further nutrient input would almost
<br />certainly be detrimental.
<br />
<br />4.
<br />
<br />Other data and observations such as pH, dissoived oxygen, and
<br />color complement the nutrient data in suggesting an enriched
<br />situation.
<br />
<br />5.
<br />
<br />At lea~t a one time monitoring of the lake each year should be
<br />continued. Discussion with the Division of Wildlife and Colorado
<br />Water Quality Control Division should be initiated to discuss
<br />possible solutions to the problem should it worsen.
<br />
<br />6.
<br />
<br />Chapter IV contains the data analysis and oasis for the above
<br />statements.
