BIG BOGGY CREEK
BIG BOGGY CREEK. Big Boggy Creek rises three miles southwest of Bay City and two miles west of the Colorado River in the Bay Prairie of Matagorda County (at 28°55' N, 95°59' W) and runs southeast for twenty-three miles to its mouth on the Gulf Intracoastal Waterway, just off East Matagorda Bay (at 28°44' N, 95°50' W). The stream is intermittent in its upper reaches. Before the construction of the waterway the creek emptied directly into the bay. Big Boggy Creek forms Boggy Lake about a mile before its mouth. As it nears the coast it forms the western border of Big Boggy National Wildlife Refuge. Upstream the terrain is low-rolling to flat and locally dissected, surfaced by deep to shallow sandy and clay loams that support grasses and hardwoods. Near the coast the terrain changes to a saltwater marshland that supports diverse plant and animal species including waterfowl, shrimp, and numerous grasses.
