This section provides more detailed information about the
physiographic, hydrologic and geological classification of the
region the watershed is in. Surface water features vary widely
throughout the state and are described here by Lake Regions—a
classification system of 47 lake region types rooted in physical
geography, soils, hydrology, biology, and chemistry. Such
information is useful for water resource managers to more
effectively manage water resources. By using data in the context
of these regional characteristics, management plans can be
developed for groups of lakes based on their regional
constraints. Lake region assignment is based on geographic
location (see map). Although described by thorough study, lake
region descriptions may be subject to change or modification in
the future.
