Sargent is a fishing, boating, and water sports community with a variable population, as most of its inhabitants are weekend commuters from larger cities such as Houston, Austin, and San Antonio. Sargent is on Farm Road 457, five miles northwest of the Gulf of Mexico and twenty-four miles southeast of Bay City in the eastern corner of Matagorda County. Approximately 500 permanent residents live in the Sargent area, while on holiday weekends the population may swell to as high as 5,000. The Sargent area, with its proximity to the Gulf of Mexico, East Matagorda Bay, the Intracoastal Waterway, and Caney Creek, is home base to many commercial and sport fisherman and shrimpers. Red drum (aka Redfish), Spotted Seatrout (aka Speckled Trout), Flounder, Blue Crab and shrimp are among the local favorites.
In addition to the local fishing, one of the unique appeals of Sargent is that many of the homesites are waterfront. Several developments, such as Caney Creek Estates became established in the late 1950s and early 1960s. Following the widespread damage caused by Hurricane Carla in 1961, other developments such as Downey's Caney Creek, Caney Court, and Caney Creek Haven were established, including new waterfront lots created by the digging of manmade canals off Caney Creek and the Intracoastal Waterway.
Many waterfront lots were originally sold as campsites. Much of Sargent still has a fishing camp influence with many recreational vehicles present, although the majority of developed homesites now have permanent dwellings. Also prevalent are the many private wooden piers and docks, where modern recreational watercraft can be docked. Most piers also have electric fishing lights that allow night fishing, particularly during the colder months where Spotted Seatrout are known to feed as they migrate inland. 
Sargent Beach, where multiple rows of beach houses in the 1960s eventually succumbed to continual beach erosion, has received more attention to preserve what remains of this relatively narrow island bordered by the Gulf of Mexico, the Intracoastal Waterway, Mitchell's Cut into East Matagorda Bay, and the San Bernard River far to the east.
Mitchell's Cut is basically the continuation of Caney Creek. Caney Creek is almost long enough to be a river and has often has brackish water, even a few miles inland. The "Pass" runs into the gulf and is 1/4 mile down the cut, past the entrance to East Matagorda Bay. The "cut" is a favorite fishing site for families, and anglers. Many favorite local boat park onshore, anchor and wade in various fishing spots are in this area, such as "Leroy's Hole." Occasionally, an incoming blue ocean current will run into the 50-foot-wide (15 m) pass at the beach-front for excellent fishing.
The cut also allows boat passage to the gulf for offshore fishing and shrimping, and is vital to the live bait and shrimp sales for the community. The "Cut" (known as the Caney Creek Gulf Cut, or Mitchell's Cut) is the only pass from Freeport to Matagorda and has obvious importance to East Matagorda Bay, Sargent, and the people who live in the general area. The shore line between Sargent's pass is a stretch of land between the gulf and East Matagorda Bay and part of the Matagorda Peninsula. The pass allows for drainage of water from Caney Creek past the Intracoastal Waterway, into the gulf or East Matagorda Bay, especially in times of large rainfall in the drainage basins adjacent to Caney Creek. There are a multitude of shifting tides, water depth, and new sandbars throughout the year. A common problem is a sand bar that runs across the cut about 100 yards out and affects the bigger shrimp boats on a low tide.
Coastal Technology Corporation from Austin, Texas received a grant from the Port of Bay City Authority (two different grants totaling $340,000) to study improving the pass.
The most notable effort to protect Sargent Beach was obtaining funding for and completing development of a granite breakwater revetment designed and installed by the U.S. Army Corps of Engineers in the early 1990s. This substructure is designed to help prevent beach erosion and protect inland homes from storm surge in the event of a tropical cyclone making landfall near the area.
In early 2017 construction began on a pier built with concrete pilings extending into the Gulf at Sargent Beach. The pier project, first proposed in 2013, was funded by the federal Coastal Impact Assistance Program (CIAP) and administered by the U.S. Fish and Wildlife Service. The structure will be a 10-foot wide pier, extending 500 feet into the Gulf, terminating with a 140 ft wide T-Head. The pier surface will be built 17.9 feet above mean low tide.
Sargent was named for George Thomas Sargent (1791-1875). Sargent and his family relocated to Texas from England in 1834. In 1838 they established permanent residence in Matagorda County, where Sargent became a major landowner. George T. Sargent and his daughter-in-law, Sarah Ann, drowned in a hurricane in 1875. They are buried in a small family cemetery located in Caney Creek Estates and maintained by local residents. The site was awarded a Historical Marker by the Texas State Historical Commission in 1986. 
The community is within the Van Vleck Independent School District.
