Lake Monitoring
The objective of this program is to
sample 132 of
Iowa’s recreational lakes and to characterize current water quality.
Because temporal variation in Iowa watersheds is great, a five-year study
was planned to
yield a stable and reliable assessment of Iowa lakes and lake watersheds.
The DNR contracted with Iowa State University to sample each lake
three times during each of the five study years (2000 through 2004).
