5203 |a"Water temperatures and transparencies (secchi depths) in Dauphin Lake, Manitoba were measured during the open water season of 1984 and 1985. Maximum measured inshore temperatures were 32.5°C and 27.0°C in 1984 and 1985, respectively. Diurnal temperature fluctuation decreased with increasing depth. Maximum daily fluctuation in 1984 was 14.5°C at 25 cm water depth. In 1984 water temperatures measured on the lake bottom at 25, 50, and 100 cm depths did not differ significantly. Water temperatures measured on the lake bottom at 50 and 100 cm in 1985 were significantly different. Mean daily temperatures were significantly warmer in 1984 than 1985. Secchi disc measurements ranged from 14-55 cm over both summers. Daily variation in secchi depth measurements was high, peaking at 34 cm on June 17, 1984. A mean secchi depth of 10 cm occurred in the fall of 1985. The large surface area, low mean depth and low-lying topography surrounding Dauphin Lake facilitates thorough wind-induced mixing of the water column. Water temperatures are usually homogeneous and are influenced by atmospheric temperatures. Wind-induced mixing is responsible for the resuspension of particulates in the water column and the resulting low transparencies"--Abstract, page v.
