This short report contains information on Waller Creek's estimated population, fecal coliform levels, land use distribution, mean baseflow, total phosphorus, and other water quality indicators.Water chemistry and biological data from Waller Creek were reviewed in order to evaluate temporal and spatial trends on this urban stream. The results of site analysis of variance indicated little discernable difference among sites and variability was high for conventional water chemistry constituents. Temporal trends were inconsistent with no notable degradation or improvements. Benthic macroinvertebrate surveys showed some significant site differences that appear to relate primarily to flow and possibly to nutrient enrichment. These surveys documented decreasing water quality over time; however, this result is apparently an artifact of the final survey, which took place after a long dry period. Overall, Waller Creek has low water quality and biological integrity when compared to other Austin area streams (worse than 75 percent of the watersheds for most measures).Waller Creek Working Grou
