Caddo Lake is a 25,400 acre (103 km²) lake and wetland located on the border between Texas and Louisiana, in northern Harrison County and southern Marion County in Texas and western Caddo Parish in Louisiana. The lake is named after the Southeastern culture of Native Americans called Caddo or Caddoans, who lived in the area from the 16th century until their expulsion in the 19th century. It is an Internationally protected wet land under the RAMSAR treaty and is the largest natural fresh water lake in the South, and the largest Cypress forest in the world. It used to be Texas' only natural lake until it was artificially dammed in the 1900s.[1]

[edit] Formation
According to Caddo legend, the lake was formed by the 1811 New Madrid Earthquake. There may be some truth to the legend, as Reelfoot Lake in Tennessee was formed by that earthquake, but most geologists now feel that Caddo Lake was formed gradually rather than catastrophically. The lake was formed, either gradually or catastrophically, by the "Great Raft" a 100 mile (160 km) log jam on the Red River in Louisiana.
[edit] History
Caddo was first seen by Native Americans in the 8th century, but substantial development would only begin with invention of the steamboat and US annexation of both Louisiana and Texas in the 19th century. The cities of Port Caddo, Swanson's Landing, and Jefferson in Texas and Mooringsport in Louisiana, had thriving riverboat ports on the lake. Gradually as the log jams where removed in the lake and the Red River by Captain Henry Miller Shreve and then by the Army Corps of Engineers, the lake changed shape and eventually fell over ten feet destroying the East Texas ports and their riverboat industry.
Industry once again came to Caddo Lake with the discovery of oil beneath it. The world's first over water oil well was completed in Caddo Lake in 1911. The Ferry Lake No. 1 was erected by Gulf Refining Company. The well bottomed at 2,185 feet and produced 450 barrels per day.
Oil derricks sprang up throughout the lake, around the turn of the 20th century, further damaging the fragile ecosystem. The oil industry left Caddo for richer fields at Kilgore and other locations in Texas. Texas tried to preserve parts of Caddo in 1934 by establishing a State Park, constructed by the WPA. The establishment of the Longhorn Army Ammunition Plant on the shores of Caddo, in the mid 20th century, polluted large portions of the surrounding wetlands until its closure in the 1990s.
[edit] Preservation efforts
In 1993 Caddo Lake preservation entered a renaissance, with the announcement that 7,000 acres (28 km²) of Caddo purchased by the Nature Conservancy were to be merged with the 483 acre (2 km²) Texas Caddo Lake State Park to be become the Caddo Lake State Park and Wildlife Management Area. In October 1993 Caddo Lake became one of thirteen areas in the United States protected by the Ramsar Convention. As of 2003 Caddo Lake flora and fauna consisted of: 189 species of trees and shrubs, 75 grasses, 42 woody vines, 216 kinds of birds, 90 fish and reptiles, and 47 mammals. One of these species, Crataegus opaca or mayhaw fruit is collected from the water to make a jelly that is considered one of the finest in the world. Forty four of Caddo's native species were either endangered, threatened or rare. From 2001 until 2003 Caddo Lake residents fought a legal battle with the City of Marshall, Texas over water rights.
Voices advocating preservation of Lake Caddo included rocker Don Henley, frontman for The Eagles.
[edit] Current threat
The lake is currently "under siege by a fast-spreading, Velcro-like aquatic fern, Salvinia molesta, also known as Giant Salvinia." Accidentally introduced to the lake by boaters, the noxious weed doubles in size every two to four days, rapidly killing off life below the surface. Most of the growth of the weed is currently on the Louisiana side, where officials have been focused on recovering from damage caused by Hurricanes Katrina and Rita in 2005.[2]
Efforts at removing the weed have included biological means via beetles that normally eat the weed but cannot survive the Texas cold and now include herbicide.
[edit] Texas Bigfoot
Since 1965 Texas' Caddo Lake has had hundreds of Bigfoot 'sightings' according to the Texas Big Foot Research Center (TBRC) as told on the Travel Channel 2006 Documentary "Bigfoot."
