Although no direct measurements of turbidity were made, the study reservoirs sometimes became highly turbid in the spring and early sum- mer during snowmelt runoff. Occasional increased turbidity, of varying duration, was observed at other times of the year during and after rainstorms. Afternoon breezes, common during the summer, occasionally created turbid conditions along the shoreline through wave action. In general, Lake Spaulding tended to have the greatest Seechi disk trans- parency and Icehouse the lowest (Figure 5). Icehouse showed greatest transparency in July, while Spaulding and Beardsley were clearest in August. The greatest primary production (photosynthesis) in most months occurred in the upper 10 m, with little or no production below 20 m (Figure 2. 3. and 4). In June and July, the oxygen maxima appeared to correspond with the carbon production maxima in Icehouse. Such a relationship was not observed in other months or in the other reservoirs. In nearly all months for each reservoir, primary production was in- hibited at the surface. Depth of maximum carbon production also corresponded to the depth of the thermocline in June and July in.
