摘要：	In 1999, the portion of the St. Johns River bounded by SR 528 and SR 46 was placed on the MFLs Priority Water Body List of the St. Johns River Water Management District (the District) (Figures 1-1 and 1-2). In May 2004, recommended MFLs were developed by the District for the St. Johns River at SR 50, in the approximate middle of this portion of the river (Mace 2004). With a comprehensive regional watershed model (HSPF), along with historic flow and stage records for the period of record (1959-2000), a baseline model of current conditions was developed (CDM 2004). Following multiple model runs with different withdrawal scenarios, the District determined that 50 million gallons per day (mgd) could be withdrawn upstream of SR 50 without exceeding the MFLs, recognizing that withdrawing 50 mgd during periods of low flow would represent a worst case scenario (CDM 2004). Since 2004, the Mace (2004) report has been updated (Mace 2005). The Mace (2005) report has been further updated and includes the addition of an infrequent low flow and level for the St. Johns River at SR 50 that has been added to the MFL criteria (personal communication with SJRWMD on September 22, 2006). This new information is not included or discussed further in this report. In addition, peer review comments were received on the Mace (2005) and HSW (2004) reports. Also, important new literature regarding the St. Johns River has been published that directly relates to the MFL work. This report provides an update based on this new information, literature sources and peer review comments. / Supplementary Notes: Sponsored by Saint Johns River Water Management District, Palatka, FL. / Availability Note: Order this product from NTIS by: phone at 1-800-553-NTIS (U.S. customers); (703)605-6000 (other countries); fax at (703)605-6900; and email at orders@ntis.gov.
