This project was undertaken as a baseline study of aquatic plant species and water quality in a set of six state parks lakes selected by the Pennsylvania Bureau of State Parks. Inventories were conducted at these lakes during the field season of 2014. Water quality parameters were measured in these lakes by staff from Pennsylvania Department of Environmental Protection’s Clean Lakes Program between 2007 and 2015. Specimens of all species observed were collected and deposited in the herbarium at the Morris Arboretum of the University of Pennsylvania. For various reasons cited in this report, the value of conducting detailed aquatic plant species/water quality analyses at these lakes was very limited. Nonetheless, this project accomplished its main goal of serving as a plant diversity baseline against which future studies can be compared.
