Abstract

In this study the diatoms show that Lily Lake had higher alkalinity and trophic status during the mid-Holocene. It is likely that the lake level was lower during this time also. At the same time the pollen shows an expansion of prairie vegetation to the lake watershed. At the end of the " prairie period " lake trophic status and alkalinity declined and forest expanded
