Minimum Flows and Levels MFL polygons

The St. Johns River Water Management District (SJRWMD) which includes all or part of 18 counties in northeast Florida, maintains a District-wide effort to develop minimum flows and levels for the protection of water bodies, water courses, associated wetlands, and aquifers from significant harm caused by water withdrawal or diversion. The minimum flows and levels (MFL) program goal is to establish minimum flows and levels for prioritized ground and surface water resources and water dependent ecosystems and to assure water for non-consumptive uses. Minimum lake levels have been established for 123 (November 2011) of the 1386 systems in the MFL lake database.圣约翰斯河水资源管理区（St. Johns River Water Management District, SJRWMD）覆盖佛罗里达州东北部18个县的全部或部分辖区，正开展全区域范围内的工作，制定最小流量与水位（minimum flows and levels, MFL）标准，以保护各类水体、水道、关联湿地及含水层免受取水或分流活动引发的显著损害。最小流量与水位项目的目标是，为经优先级排序的地下与地表水资源以及水依赖型生态系统确立最小流量与水位标准，并保障非消耗性用水的供给需求。截至2011年11月，MFL湖泊数据库内的1386个湖泊系统中，已有123个确定了最低湖泊水位。
