Info

is a variation of the Seminole word 'weekiwachee' (which means 'little spring' or 'winding river') neither the river nor the place name is identified on maps prior to 1838. A historical marker at mouth of the River reads: The Village of Bayport, located at the mouth of the Weekiwachee River sprang up in the early 1850's as a supply and cotton port. During the War Between the States, Union naval squadrons blockaded Florida's coasts to prevent goods and supplies from passing into and out of the State. By 1863 the East Gulf Blockade Squadron effectively closed the larger ports along the Gulf Coast. Small rivers, such as the Weeki Wachee became important trade routes. Shipping at Bayport attracted the attention of The Union Blockade Squadron which intercepted eleven blockade runners near there between 1862 and 1865. After the war Bayport became Hernando County's major outlet for lumber and agricultural products, and continued to serve as its transportation center until railroad service came to Brooksville in 1885." The center piece of Bayport appears to have been the Bayport Hotel which was in existence from 1842 until 1942 when it burned. Union solders escaped through Bayport following the Brooksville 1940 – Purchased by City of St. Petersburg for water supply. 1947 – First mermaid show opened on 10/13/47. 1959 – Purchased by American Broadcasting Corporation 1961 – Follow that Dream (Elvis Presley) filmed on site. 1982 – Buccaneer Bay Waterpark opens. 1984 – Purchased by Florida Leisure Attractions from ABC. 1989 – Purchased by Florida Leisure Acquisitions from Florida Leisure Attractions. 2001 – Purchased by SWFWMD, along with surrounding land. Attraction leased to current operators. 2003 – Attraction lease transferred to City of Weeki Wachee. Raid of 1864. Bayport was a productive fishing community during its heyday and a haven for smuggling during the prohibition era. As recent as 2000, the US Census Bureau continued to recognize Bayport as a Census Designated Place (CDP) consisting of 0.7 mi 2 with a population of 36. Arguably the strongest name recognition is associated with the tourist attraction that has existed at the head springs since 1947. For sixty years this attraction has been famous for the underwater mermaid shows and as a bathing place 6 . A chronology of events surrounding the attraction is given in the side bar. 2.2 Climate / Meteorology The climate of the Springs Coast is mild and greatly influenced by the Gulf of Mexico. Mean daily summer high temperatures are in the low to mid 90s and the winter means are in the upper 50s with an annual average temperature of (70 F). Annual precipitation 6 Chapter 64E-9, F.A.C. requires 500 gallons/day/bather and 100 ft 2 . Capacity is space limited at Weeki Wachee as median flows (1984-2004) are adequate to support over 200,000 bathers ____________________________________________________________________________________________ Proposed Minimum Flows and Levels for Weeki Wachee River Page 20 of 164 Watershed Characteristics
averages 55.8 inches at nearby Brooksville (1904-2004) and is largely the result of localized convective thunderstorms during the summer months when 31.7 inches (June through September) is normal. However, unlike runoff-dominated rivers this seasonal peak in rainfall does not translate into large differences in discharge (see Weeki Wachee Discharge). Additional rain accompanies winter frontal systems which result in a secondary peak in rainfall during February through April when another 9.8 inches can be expected. These cold fronts result in an average of 5 freezing days per year (1892- 2006) but can range up to 24/yr (1920). During the last century (1905-2005), a hurricane has passed within 65 nautical miles (nm) of the Weeki Wachee River at an average interval of 6.2 years. Table 2-2 and Figure 2-6 summarize the Category 1 or higher storms that have passed within 65 nm of Bayport during the past 100 years. Of particular note is the 27 year absence of activity between hurricane Gladys (10/1968) and hurricane Erin (8/1995).
