Arroyo de la Cruz Fecal Indicator Bacteria TMDL


Problem Statement - Waterbodies in the Arroyo de la Cruz watershed are impaired due to exceedance of E. coli water quality criteria. Consequently, the Basin Plan general toxicity objective is not being protected. However, the nature of the impairment appears to be quite moderate and exceedances of E. coli water quality criteria are not routine. This project identifies the causes of impairment and describes solutions to achieve water quality objectives and protection of beneficial uses.
