Matagorda County was founded in 1836. Matagorda County is named for the canebrakes which once grew along the coast. Matagorda is a Spanish word meaning thick bush. As of 2010, the population of Matagorda County is 36,702.

Matagorda County receives annual rainfall averages of 42 inches. Several historic storms affected the area and large amounts of rainfall are not uncommon in this area, even if they are not associated with hurricanes. For example, a tropical storm produced 10 inches of rain in 1921 and another storm produced nearly 12 inches in 1922 in a short period of time. A one-day rainfall accumulation was recorded at 21 inches in October 1983.

Matagorda County entered the regular National Flood Insurance Program (NFIP) in April 1971. ,
