Giardia usually has a 1-3 week incubation period. If it hits you while you are still out, it probably isn't Giardia.

~1000 Typical swimming pool contamination
~100 Giardiasis is plausible
~10 Minimum needed to contract giardiasis
~1 Some wilderness water outside California
0.12 Some San Francisco water
0.108 Worst Sierra Nevada water
0.030 Some Los Angeles Aqueduct water
0.013 Mt. Whitney at Trail Camp
0.003 Mt. Whitney at Whitney Portal
The highest concentration of Giardia cysts was 0.108 per liter of water in Susie Lake, south of Lake Tahoe. The next highest was 0.037 per liter near Long Lake, southwest of Bishop. Samples taken in the Mt. Whitney area varied from 0 (most sites) to 0.013 (Lone Pine Creek at Trail Camp) per liter. The concentration was 0.003 per liter in Lone Pine Creek at Whitney Portal.
Recall that San Francisco water can contain a concentration approaching 0.12 cysts per liter, a figure now seen to be higher than that measured anywhere in the Sierra.
