The Alachua County boundary extends to the ordinary high water line (normally the shoreline), which is 141 feet (43 m) above mean sea level. It forms the headwaters of the Santa Fe River, exiting from a "little" northern area (Little Lake Santa Fe) emptying into the Suwannee River.
A high water mark is not necessarily an actual physical mark, [4] but it is possible for water rising to a high point to leave a lasting physical impression such as floodwater staining. A landscape marking left by the high water mark of ordinary tidal action may be called a strandline and is
Bulkhead line is an officially set line along a shoreline, usually beyond the dry land, to demark a territory allowable to be treated as dry land, to separate the jurisdictions of dry land and water authorities, for construction and riparian activities, to establish limits to the allowable obstructions to navigation and other waterfront uses.
Florida: Georgia: Marker on Chattahoochee riverbank is actually a few feet above and west of true tripoint at high-water line. [2] Alabama: Georgia: Tennessee: Tri-State Corner. Marker on dry land at surface level and unmarked on lake in cavern directly below.
Water drains from the lake into the Floridan Aquifer through the sinkholes. These are usually partially or completely plugged with sediments, but collapse when groundwater levels drop [citation needed], allowing lake water to funnel into the aquifer, which can completely drain the lake. This has occurred on numerous occasions.
A series of canals and high capacity pumps allowed the water to be introduced for irrigation and flooding or to discharge it when necessary. The phosphate laden water created a hypereutrophic condition resulting in algal blooms, robbing the lake water of oxygen and sunlight necessary to sustain plant life on the lake bottom. Over the decades ...
Following is a list of dams and reservoirs in Florida. All major dams are linked below. The National Inventory of Dams defines any "major dam" as being 50 feet (15 m) tall with a storage capacity of at least 5,000 acre-feet (6,200,000 m 3 ), or of any height with a storage capacity of 25,000 acre-feet (31,000,000 m 3 ).
Mean high water (MHW) is the average of all the daily tidal high water levels observed over a period of several years. It is not the same as the normal tidal limit. In the United States this period spans 19 years and is referred to as the National Tidal Datum Epoch. [7]
