| Houston Ship Channel | 1006 | Unnamed Tributary of Halls Bayou | From the confluence with the San Jacinto River in Harris County to a point immediately upstream of Greens Bayou in Harris County, including tidal portions of tributaries. Sub-Segment 1006D: Halls Bayou Below US 59 (unclassified water body).From the confluence with Greens Bayou up to US 59 in Harris County. Sub-Segment 1006E: Halls Bayou Above US 59 (unclassified water body).From US 59 upstream to Frick Road. Sub-Segment 1006F: Big Gulch Above Tidal (unclassified water body). From the confluence with Greens Bayou Tidal to Wallisville Road in Harris County. Sub-Segment 1006H: Spring Gully Above Tidal (unclassified water body).From confluence with Greens Bayou to US 90 in Harris County. Sub-Segment 1006I: Unnamed Tributary of Halls Bayou (unclassified water body).From the confluence with Halls Bayou to a point 0.13 miles upstream of Richland Drive in Harris County. Sub-Segment 1006J: Unnamed Tributary of Halls Bayou (unclassified water body).From the confluence of Halls Bayou (east of US 59 and south of Langley | The tidal portion of the Houston Ship Channel is heavily developed. The lower portion of the watershed includes the Cities of Deer Park, Channelview, Houston, Pasadena, and parts of unincorporated Harris County. Heavy industrial complexes line both sides of the channel in the lower part of the watershed. The eastern end of this segment is Carpenters Bayou, which has four tributaries: Tucker Bayou, Patrick Bayou, Boggy Bayou, and Glenmore Ditch. On the south shore of the western end of the watershed is the confluence with Greens Bayou which also received heavy barge traffic. Tributaries to Greens Bayou include: Goodyear Creek, Jordan Gully, Big Gulch, Spring Gully, Halls Bayou, and an unnamed tributary. The Halls Bayou area is predominantly residential and commercial with some light industry. The majority of the area is on sanitary sewer, however there are scattered on-site sewer facilities scattered throughout the watershed. | Of the four uses, aquatic, recreation, fish consumption, and general, for which 1006 (Houston Ship Channel Tidal) is designated none are fully supported. All of the tributaries to 1006 are designated for recreation and all were found to not support the recreation use due to elevated levels of bacteria. E. coli levels exceeded the criteria of 394 MPN 74% of the time (760 out of 1025 samples) and are listed as impaired in both the 2008 and Draft 2010 Texas Integrated Reports (IRs). Enterococci levels were found to exceed the criteria of 500 MPN in three assessment units, 1006_01, 1006_03, and 1006_05. | Watershed Map |
