For lake index site monitoring volunteers observe, measure, and record environmental data
as well as collect water samples. Lake index site monitoring is done away from the shoreline,
so it requires the use of a boat, canoe, or kayak. Environmental data that is recorded is very
similar to those recorded by screening and baseline monitors and include parameters such
as air/water temperature, wind conditions, wildlife present, Secchi disk depth, and overall
perception of the condition of water body. During each sampling event two water samples
are collected and sent to the State Health Lab in Pierre for analysis. There, parameters such
as pH, Ammonia, Nitrates, TKN, and total Phosphorous are determined. Locations are
sampled twice a month between

April and November. However, due
to the hours kept by the State
Heath Lab samples must be
collected during the day, Monday
through Thursday, so that they can
be analysed within 24 hours of
their collection. Because of these
conditions, Lake Index Site
Monitoring is a best fit for those
who own thier own watercraft and
have a flexible schedule on
weekdays.
