Water Planning Data for Region P (Lavaca)
Arenosa Creek
From the confluence with Garcitas Creek in Jackson/Victoria County upstream to its headwaters along the northern boundary of Victoria County.
- High water quality/exceptional aquatic life/high aesthetic value - ecoregion Stream (Bayer et al. 1992); Benthic macroinvertebrates (Bayer et al. 1992 and Davis 1998)
Garcitas Creek
From the confluence with Lavaca Bay in Jackson/Victoria/Calhoun County upstream to the Arenosa Creek confluence in Jackson/Victoria County.
- High water quality/exceptional aquatic life/high aesthetic value - ecoregion Stream, Dissolved oxygen (Bayer et al. 1992); Benthic macroinvertebrates (Bayer et al. 1992 and Davis 1998)
- Threatened or endangered species/unique communities - one of only a few locales in Texas where Texas palmetto occurs naturally (Ortego 1999); diamondback terrapin (Ortego 1999)
Lavaca River
From the confluence with Lavaca Bay in Calhoun/Jackson County to a point 5.3 miles downstream of US 59 in Jackson County (TNRCC stream segment 1601).
- Biological function - extensive freshwater wetland habitat displays significant overall habitat value (Bauer et al., 1991)
- Threatened or endangered species/unique communities - diamondback terrapin (SOC) (B. Ortego, 1999, pers. comm.)
West Carancahua Creek
From the confluence with Carancahua Creek in Jackson County upstream to the FM 111 crossing east of Edna in Jackson County.
- High water quality/exceptional aquatic life/high aesthetic value - ecoregion stream; high water quality, diverse benthic macroinvertebrate community (Bayer et al., 1992)
West Mustang Creek
From the point where East Mustang Creek and West Mustang Creek join to form Mustang Creek in Jackson County upstream to FM 1160 in Wharton County.
- High water quality/exceptional aquatic life/high aesthetic value - ecoregion stream; diverse benthic macroinvertebrate community (Bayer et al., 1992)
