    Surface Water Management Plan Water Resources | City of St. Louis Park Proposals are due 4:00 p.m. April 24, 2017 Executive Summary City of St. Louis Park Surface Water Management Plan Executive Summary Located in Hennepin County just west of Minneapolis, the 10.7-square-mile City of St. Louis Park is a fully developed suburban community. The population of St. Louis Park is approximately 48,000 residents, making it the 20th largest city in Minnesota. St. Louis Park contains a variety of physical and water resources including several wetlands and small lakes, wooded areas, parks, and recreational lands, as well as the Minnehaha Creek corridor. Two watershed management organizations (WMOs) cover St. Louis Park, each with its own governing body: the Bassett Creek Watershed Management Commission (BCWMC) and the Minnehaha Creek Watershed District (MCWD). This local Surface Water Management Plan (SWMP) was prepared in accordance with Minnesota Statute 103B.235 and Minnesota Rules 8410 and is intended to replace the 2009 plan. The purpose of this SWMP includes objectives outlined in Minnesota Statute 103B.201 for metropolitan water management programs. According to the statute, the purposes of these water management programs are to: • protect, preserve, and properly use natural surface and groundwater storage and retention systems; • minimize public capital expenditures needed to correct flooding and water quality problems; • identify and plan for means to effectively protect and improve surface and groundwater quality; • establish more uniform local policies and official controls for surface and groundwater management; • prevent the erosion of soil into surface water systems; • promote effective groundwater recharge; • protect and enhance fish and wildlife habitats and water recreational facilities; and • secure the other benefits associated with the proper management of surface and groundwater.

  • Reclamation of Tailings Ponds
    Journal American Society of Mining and Reclamation, 2012 Volume 1, Issue 1, COMPARISON OF HYDROLOGIC CHARACTERISTICS FROM TWO DIFFERENTLY RECLAIMED TAILINGS PONDS; GRAVES MOUNTAIN, LINCOLNTON, GA1 Gwendelyn Geidel2 Abstract: This study compares and evaluates the hydrologic characteristics between two kyanite ore process tailings ponds that were reclaimed with different reclamation strategies; one reclaimed with an impermeable membrane and the other with an open, surface reconfiguration (OSR) methodology. During the extraction and processing of kyanite ore from the Graves Mountain mine, Lincoln County, Georgia, fine grained tailings were produced. The tailings were transported by slurry pipeline to various tailings ponds which were created by the construction of dams using on-site materials. The first study site, referred to as the Pyrite Pond (PP), was constructed and filled during the 1960’s and early 1970’s. In early 1992, the PP was capped with an impermeable membrane, covered with a thin soil veneer and vegetated and in 1998 the upslope reclamation was completed. The second tailings pond, referred to as the East Tailings Pond (ETP), was constructed and filled in the 1970’s and early 1980’s and was reclaimed in 1995-96 by surface reconfiguration and the addition of soil amendments. Piezometers and wells were installed into the two tailings ponds and also in close proximity to the tailings ponds. While the initial study was aimed at comparing the two reclamation strategies, it became apparent that the ground water was a dominant factor. Results of the evaluation of the potentiometric surface data for varying depths within each tailings pond indicate that while both tailings ponds exhibit delayed response to precipitation events suggesting infiltration effects, the delay in the ETP deep wells and PP wells could not be adequately described by a surface infiltration model.
