Values reported on the enclosed DMRs represent the maxirrutm(or <br />minimum as applicable) montlily/daily values generated at each outfall during the quarter. <br />Also enclosed are monthly NOAA weather summaries for the reporting period, seep volume data for site 011, and <br />WET test report forms as applicable. Three outfalls were sampled for WET analyses during the quarter. Two <br />species acute tests were completed at outfalls 001 and 011 during the first quarter and a single species acute test (P. <br />promelas) was completed at outfall 002.
