From This Day in Texas History
In 1838, the keelboat David Crockett, reportedly the first large craft to navigate the Colorado River, arrived at the head of “the raft on the Colorado.”
Early in the 19th century, the river’s slow current caused a logjam, or “raft,” which by the late 1830s blocked the river 10 miles above its mouth at Matagorda.
The Crockett, which had averaged more than 60 miles a day, stopped at the head of the raft, where its cargo of cotton was unloaded and carried by wagon to Matagorda.
Removing the log jam in the 1920s caused the development of an enormous delta that reached across Matagorda Bay to Matagorda Peninsula.
In 1936 engineers dug a channel through the delta.
