Recovery of the fish population of a municipal wastewater-dominated, north Texas creek after a major chlorine disturbance

This study evaluated the effects of a major chlorine disturbance on fish communities in Pecan Creek by the City of Denton's Pecan Creek Water Reclamation Plant. Fish communities in Pecan Creek were sampled using a depletion methodology during February, April, July, and November, 1999. February and April sampling events showed that the fish communities were severely impacted by the chlorine. Sampling during July and November showed fish communities recovered in Pecan Creek.
