Lake McQueeney is a reservoir on the Guadalupe River located 5 miles (8 km) west of Seguin in Guadalupe County, Texas, USA. It was formed in 1928 by the construction of a dam to provide hydroelectric power to the area. Management of the dam and lake was assumed by the Guadalupe-Blanco River Authority on May 1, 1963. The lake's prominent feature is Treasure Island, a residential area that has been subjected to major flooding in 1972, 1998, and 2002. Most of it is approximately 10 feet (3 m) deep, with deeper sections along the center channel of the river. It is a venue for outdoor recreation, including fishing, boating, and swimming, and is maintained at a constant level year round.
Fish and plant life
The lake has been stocked with species of fish intended to improve the utility of the reservoir for recreational fishing. Fish present in it include catfish, white crappie, sunfish, spotted bass, and largemouth bass. Vegetation in the lake includes cattail, pondweed, American lotus, spatterdock, rushes, water hyacinth, water lettuce, and hydrilla.
There are no public parks or free boat ramps on the lake's shore. Many private homes line the perimeter of it. In the center is an extensively developed island called Treasure Island on which many vacation and summer homes have been built.
