La Nana Bayou Watershed

La Nana Bayou
La Nana Bayou

La Nana Bayou is a 32-mile freshwater stream that extends from the confluence of the Angelina River south of Nacogdoches in Nacogdoches County to the upstream perennial portion of the stream north of Nacogdoches in Nacogdoches County. Routine water quality monitoring began in 1996 and led to the inclusion of La Nana Bayou on the Texas 303(d) List in 2000 as being impaired for bacteria. It remains impaired for not meeting its primary contact recreation standard. Concerns for elevated ammonia-nitrogen, nitrate-nitrogen and total phosphorous exist in the downstream portion of the bayou.

TWRI is establishing a baseline of information and completing an initial analysis for the La Nana Bayou Watershed that will allow for future WPP development by:

  • Characterizing potential causes and sources of pollution through water quality and watershed-related data gathering and assessment
  • Collecting additional targeted, intensive water quality monitoring data to refine existing water quality information and fill data gaps
  • Engaging watershed stakeholders through public participation programs including general education program delivery and meeting with key stakeholders to understand water quality issues and determine a preferred restoration approach

Institute works with partners to improve water quality in East Texas


The Texas Water Resources Institute, Texas Commission on Environmental Quality and the Angelina and Neches River Authority will host a meeting Nov. 22 in Lufkin for anyone interested in water quality impairments in Jack, Cedar, Hurricane and Biloxi creeks, tributaries of the Neches River below Lake Palestine.


The Texas Water Resources Institute in collaboration with the Texas Commission on Environmental Quality will host two meetings Nov. 21 in Woodville and Jasper for anyone interested in joining a partnership to improve and protect water quality in the Sandy and Wolf creeks.


A Texas Watershed Steward workshop on water quality related to the Neches River will be held from 1-5 p.m. May 21 in Jasper. The workshop will be held at the Jasper County Courthouse Annex, 271 E. Lamar St. It will be presented by Texas A&M AgriLife Extension Service and the Texas State Soil and Water Conservation Board in cooperation with the Texas Water Resources Institute.
