March 19 2008 identified several assessment units in the Lower Leon Creek as being impaired based on the stateâ s contact recreation bacteria and high aquatic life dissolved oxygen use criterion In response to these conditions the TCEQ Total Maximum Daily Load Program in partnership with the San Antonio River Authority SARA initiated a project to verify depressed dissolved oxygen and develop information necessary to support a bacterial E coli Total Maximum Daily Load TMDL in the Lower Leon Creek Segment 1906 The specific objectives of the Leon Creek Segment 1906 TMDL for Dissolved Oxygen and Bacteria Impairments TCEQ contract number 582 8 80193 were to 1 Collect targeted 24 hour dissolved oxygen data in order to verify the water quality impairment and overall organic loading 2 Collect targeted bacterial data in order to establish source of impairment and over loading 3 Conduct modeling and assessment activities required to allocate loading 4 Provide technical assistance to the TCEQ in the evaluation of actions necessary to achieve the recommended loading allocations and 5 Document compile and summarize technical analyses in reports to the TCEQ There were two phases to this project Phase I addressed dissolved oxygen deficiencies in Leon Creek Phase II addressed excessive bacteria concentrations View Report Bacteriological Assessment of the Lower San Antonio River Citizens in the lower portion of the San Antonio River Watershed have expressed concerns about bacteria levels in the San Antonio River and asked that the San Antonio River Authority address their concerns Many felt that the City of San Antonio was the principle source of the bacterial concerns on the lower San Antonio River Segment 1901 However since water quality data showed that the stream standard for contact recreation was generally being met at sites on the San Antonio River from I 37 in Bexar County to FM 791 in Karnes County it was likely that the concerns identified in the lower portion of the River had other sources Therefore this study was designed to concentrate its limited resources on Segment 1901 Segment 1901 encompasses the area from the confluence with the Guadalupe River in Refugio and Victoria Counties to a point approximately 600 meters downstream of the FM 791 bridge near Falls City Texas in Karnes County Limited fecal coliform bacteria data has identified several areas where the State stream standard for contact recreation has occasionally not been met in this segment and the segment has been placed on the Texas 2002 Clean Water Act Section 303 d List of impaired water bodies This study was designed to collect and analyze surface water samples from the lower San Antonio River in order to identify reaches that may or may not be meeting the State stream standard for contact recreation and attempt to identify the source s of bacterial contamination View Report Inventory of Fishes at San Antonio Missions National Historical Park SAAN Under contract to the National Park Service biologists of the San Antonio River Authority Environmental Services Department conducted a series of fish collections at representative sites along watercourses in or adjacent to the San Antonio Missions National Historical Park properties in Bexar and Wilson counties Texas Fishes were collected from October 2003 to September 2004 at five sites along the San Antonio River and at three tributary sites utilizing electro fishing and seining techniques Fish community composition habitat and water quality were evaluated The survey collected 27 species totaling 4912 individuals Non native species collected during this survey made up 37 of all species collected and 36 of all individuals collected The survey was able to document 69 of the fishes previously collected from the Upper San Antonio River and collected four species Notropis Buchanani Notropis texanus Notropis amabilis Tilapia zilli not previously listed by the San Antonio River Authority No darter species or species of management concerns were collected The San Antonio River Authority developed an inventory of fishes collected from streams within or adjacent to San Antonio Missions National Historical Park properties as a project deliverable to the National Park Service View Report Linking Freshwater Inflows and Marsh Community Dynamics in San Antonio Bay to Whooping Cranes From 2002 through 2009 faculty and students from the Department of Wildlife and Fisheries Sciences at Texas A M University conducted field laboratory and modeling studies to investigate the diet behavior and habitat of the whooping crane Grus americana at Aransas National Wildlife Refuge ANWR Texas During this period the research team also conducted complementary studies of environmental conditions in San Antonio Bay The project was called the San Antonio Guadalupe Estuarine System SAGES project and was funded primarily by the Guadalupe Blanco River Authority and the San Antonio River Authority with additional support provided by the San Antonio Water System and the Texas Water Development Board The U S Fish and Wildlife Service provided in kind support through lodging the use of boating facilities and other logistics View Report San Antonio River

    Settlement Fertile soil open range and the San Antonio River continued to attract settlers from Nueva España in the 1700s followed by settlers coming west from the United States in the early 1800s German Czech and Polish immigrants established tight knit farming communities throughout the area including the first organized Polish settlement in the United States Panna Maria in Karnes County As the 19th Century progressed so did the River Basin Railroads were built more settlers arrived and large scale agricultural production began Bexar County The headwaters of the San Antonio River are in Bexar County and the River is the reason for the area s early settlement Spanish soldiers established a presidio in 1716 making the first civil settlement possible in 1731 From 1718 to 1731 the missionaries established their five compounds and acequias to convert the Indians to Christianity and an agricultural way of life When the first Anglo Americans arrived in 1821 the little town of San Antonio de Béxar was home to about 2000 Mexican colonists and soldiers In the 1830s the battle for Texas independence from Mexico began marked by the fall of the Alamo in 1836 and ending with the defeat of Santa Anna at San Jacinto that same year After Texas became a state in 1845 the number of European and Anglo settlers increased dramatically and the county s population and economy accelerated Today San Antonio is the 7th largest city in the United States and its colorful history charming River Walk and rest red missions make it a popular tourist destination After Mexico won independence from Spain in 1821 the new government began secularizing the missions Most mission property was distributed to the Indian inhabitants or sold to private parties by 1794 However Mission Espíritu Santo remained in Franciscan hands until 1830 Missions Bexar County est 1718 Mission San Antonio de Valero The Alamo est 1720 Mission San José San Miguel de Aguayo est 1731 Mission Nuestra Señora de la Concepción est 1731 Mission San Juan Capistrano est 1731 Mission San Francisco de la Espada Wilson County est 1731 Rancho de las Cabras Goliad County est 1749 Nuestra Señora de Loreto Presidio La Bahía est 1749 Mission Nuestra Señora del Espíritu Santo de Zúñiga Wilson County When the Spanish established the chain of missions along the upper San Antonio River they also established ranches to supply cattle goats sheep mules and horses to the missions Many of those ranches were in the area now known as Wilson County where ranching is still a major part of the economy Anglo American German and Polish settlers began arriving in the 1850s and an act of the Texas legislature established Wilson County in 1860 After the courthouse burned in 1883 county officials hired the noted architect Alfred Giles to draw up plans for the present day courthouse in Floresville Today Wilson County is a leading producer of peanuts and in the industrial arena provides oil and gas field services and produces structural clay products and
