Abstract

This report was prepared under a contract between Limno-Tech, Inc. (L TI) and the Southwest Florida Water Management District (SWFWMD) for a diagnostic assessment study of the Upper Hillsborough River watershed. The Hillsborough River drains more than 695 mi2 of predominantly agricultural lands in Pasco, Polk, and Hillsborough Counties. The present investigation focused on a 650 mi2 area encompassing the northern and central drainage segments of the Hillsborough River Watershed (Figure E-1). Of particular concern to this investigation is the Hillsborough River reservoir, which is designated as a Class I water based on its use as a potable water supply. Water quality in the reservoir is characterized by low dissolved oxygen, and high concentrations of nutrients and metals. Seasonally occurring algal blooms are mitigated by the routine application of copper sulfate-based algaecide by the City of Tampa.
