| 520 | 3 |a"Water chemistry and biological indices did not indicate that the domestic sewage effluent entering Lynx Lake through an unnamed creek was having a detectable effect. It is theorized that nutrient regeneration within this type of small lake is a natural occurrence and, as evidenced in Erickson Lake, the control lake, can support algal blooms of 100 µg/1 chlorophyll-a. Although blue-green algae made up a dominant portion of the phytoplankton in both lakes, the overall variety of phytoplankton was greater in Lynx Lake. Zooplankton standing crop was also greater in Lynx Lake and this may be attributed to the more diverse phytoplankton flora. It is felt that due to the naturally high productivity of these lakes and the development of anoxic conditions during the late summer, fish habitation would be restricted to the upper region of the water column"--Abstract, page i. |
