  • Chapter 1: the Everglades to the 1920S Introduction
    Chapter 1: The Everglades to the 1920s Introduction The Everglades is a vast wetland, 40 to 50 miles wide and 100 miles long. Prior to the twentieth century, the Everglades occupied most of the Florida peninsula south of Lake Okeechobee.1 Originally about 4,000 square miles in extent, the Everglades included extensive sawgrass marshes dotted with tree islands, wet prairies, sloughs, ponds, rivers, and creeks. Since the 1880s, the Everglades has been drained by canals, compartmentalized behind levees, and partially transformed by agricultural and urban development. Although water depths and flows have been dramatically altered and its spatial extent reduced, the Everglades today remains the only subtropical ecosystem in the United States and one of the most extensive wetland systems in the world. Everglades National Park embraces about one-fourth of the original Everglades plus some ecologically distinct adjacent areas. These adjacent areas include slightly elevated uplands, coastal mangrove forests, and bays, notably Florida Bay. Everglades National Park has been recognized as a World Heritage Site, an International Biosphere Re- serve, and a Wetland of International Importance. In this work, the term Everglades or Everglades Basin will be reserved for the wetland ecosystem (past and present) run- ning between the slightly higher ground to the east and west. The term South Florida will be used for the broader area running from the Kississimee River Valley to the toe of the peninsula.2 Early in the twentieth century, a magazine article noted of the Everglades that “the region is not exactly land, and it is not exactly water.”3 The presence of water covering the land to varying depths through all or a major portion of the year is the defining feature of the Everglades.

  • Historical Resources
    Application for Corridor Extension Historical Resources Historical Resources Although the Green Mountain Scenic Byway CME considers the proposed corridor eligible for designation on the strength of its recreational and natural resources, the corridor extension could be designated on the strength of its historical resources. The City of Mount Dora has created a Historic Preservation Review Area which is located within a larger National Register of Historic Places District. The entire Review Area is included within the proposed corridor extension. The extension connects the historic downtown of Winter Garden with the historic downtown of Mount Dora. Narrative The colonization of Florida by the Spanish proved disastrous to the Native Americans. Waves of epidemics of infectious diseases introduced from Europe crashed upon the Native Americans. Between 1565, the year that the Spanish founded St. Augustine, and 1595, when serious Catholic missionary attempts began, it is estimated that the Timucua speaking population had plummeted from about 150,000 to about 50,000. To add to the devastation of disease, savage raids by Creek and Yamasee Indians, often supported by Carolina colonists, further reduced the population. By 1700, the Timucua had been reduced to about 1,000 people. The remaining Timucua attempted to seek refuge from the raids at St. Augustine, but by 1753 only 136 Timucua remained. When the British took Florida from Spain in 1763, the few that were left were expelled from the St. Augustine area. A pitifully few Timucua moved south and tried to settle on the Tomoka River. It is possible that their descendants eventually joined the Seminoles. The Seminoles were originally part of the Creek Confederacy.

The natural flow regime of the contributing river is considered to be the baseline for assessing the effects of withdrawals. Development of the percent-of-flow approach has emphasized the interaction of freshwater inflow with the overlap of stationary and dynamic habitat components in tidal river zones of larger estuarine systems. Since the responses of key estuarine characteristics (e.g., isohaline locations, residence times) to freshwater inflow are frequently nonlinear, the approach is designed to prevent impacts to estuarine resources during sensitive low-inflow periods and to allow water supplies to become gradually more available as inflows increase.
