(fact sheet #1 of the Shoreland Management and Lake Classification Series) BACKGROUND Wisconsin is home to 15,000 lakes of varying types: from massive flowages to small town millponds, from highly developed urban lakes to undeveloped fiwildernessfl lakes. Lake basins are formed due to endogenous geological processes like tectonism and volcanism and exogenous activities like landslides, glaciation, solution, river and wind action. This paper. The majority of lakes on Earth are fresh water, and most lie in the Northern Hemisphere at higher latitudes.
