Nolan Creek: Watershed Based Planning and Assessment

A project that collected water quality data to characterize the creek and provide a basis for developing a watershed protection strategy.


Nolan Creek was identified as impaired because of elevated bacteria concentrations in 1996. In 2010, TCEQ determined that water quality standards for this water body should be reviewed before a development of a total maximum daily load (TMDL) was scheduled. Concerns about elevated levels of nitrate and phosphorus were also noted in 2010.
