Abstract/Description or Keywords | In 2008, the BC Conservation Foundation collected baseline stream productivity data to determine nutrient and productivity status of Gold Creek, a major tributary to Alouette Lake. Monitoring of water chemistry, algal growth, temperature and discharge was conducted throughout the summer growing months, July to September, while fish size and abundance were sampled in October. Resulting analysis of water chemistry and algal accumulation clearly indicated ultraoligotrophic conditions. Ortho-phosphorus and total dissolved phosphorus values were below detection limits (1 and 2 ug/L respectively) on all sampling dates, and total phosphorus values were also at lower detection limit levels (2 ug/L). Overall, nitrogen was in excess of biological requirements, indicating a phosphorus-limited stream ecosystem. Chlorophyll a concentrations were all below 1 ug/cm2 which indicated low primary productivity, consistent with the near absence of phosphorus in the water chemistry sampling. The numbers of trout fry at each sampling site appeared to be very low, less than 5 fry per 100m2 . |
