Limnological tower
Limnological tower at Rutland Water
- ... that limnological towers (example pictured) can be used to predict algal blooms that may have an adverse effect on drinking water quality? "The main difficulties encountered when treating algal blooms in British reservoirs are recorded (Collingwood 1976) as being through filter blockages, reduced filter runs, taste and odour problems and through variable pH . The possibility of encountering similar problems at Rutland Water was therefore foreseen and after consultation with the Water Research Centre (W .R .A . 1971; Lack & Collingwood 1975) the design features previously described (Harper 1978), such as the provision of two draw-off towers with multiple draw-off levels and the limnological tower, were included to help deal with these problems ... Temperature, fluorescence and oxygen percentage saturation can be continuously monitored at 2m depth intervals on the limnological tower . The results are transmitted by telemetry to the Control Room below the dam and read on visual display units . This provides instantaneous information on thermocline formation and on vertical distribution of algae." from Ferguson, A. J. D.; Harper, D. M. (1 March 1982). "Rutland water phytoplankton: the development of an asset or a nuisance?". Hydrobiologia. 88 (1): 117–133. doi:10.1007/BF00008304. ISSN 1573-5117.
- ALT1:... that in the 1960s limnological towers made from 4-inch (100 mm) water pipe were constructed in the Great Lakes to study water conditions? "In the spring of 1961 the Great Lakes Institute established 6 meteorological observation towers in three of the Great Lakes ... The tower shaft was made of standard 4-in black water pipe" from Deane, Roger E. (1 April 1963). "Limnological and meteorological observation towers in the Great lakes". Limnology and Oceanography. 8 (1): 9–15. doi:10.4319/lo.1963.8.1.0009. ISSN 1939-5590.

for ALT0, as the more compelling IMO. The article is new enough and long enough. The hook facts are cited inline, the article is neutral and I detected no copyright or plagiarism issues. The image is freely licensed. --K.e.coffman (talk) 02:14, 14 November 2019 (UTC)
