Lake Monitoring
In 2006, the Watershed Assessment Branch resumed sampling lake, reservoir, and pond waterbodies after an
absence of activity since 1996. Using the rotating Watershed Basin Schedule, much like TMDL sampling, and
the targeted Wadeable Stream Monitoring, sampling occurs on targeted lakes (within the watershed group for
that year) four times during the summer months (May-August). The number of stations per lake varies and is
generally proportional to the size of the lake or the number of major branches or arms of the lake. The
components of sampling include a vertical water chemistry profile (including the physiochemical properties,
nutrients, and turbidity measurements), chlorophyll-a and fecal coliform sampling, Secchi depth, and some
limited habitat and disturbance observations.
