BEARGRASS CREEK WATERSHEDThe Beargrass Creek Watershed is probablythe most diverse watershed in terms ofgeographic area and land usage. The entirearea covers approximately 61 square milesand is divided by three major sub-basins —the Muddy Ford, the Middle Fork and theSouth Fork.All three sub-basins flow from suburbanareas that were developed — and continueto develop since the early 1960s. They flowthrough many older neighborhoods, such asthe Highlands, Germantown, Phoenix Hilland Butchertown before they cometogether and flow into the Ohio River justabove the downtown Louisville area.I 71I 71Brownsboro RoadI 265I 64BroadwayFrankfort AvenueI 264Shelbyville RoadI 264I 65I 64Bardstown RoadTaylorsville RoadI 64LouisvilleInternationalAirportI 264Bardstown RoadI 265DixieHighwayI 65PrestonHighwayOuter LoopI 265Bardstown RoadI 265Big Rock in Cherokee Park — one of Louisville’smost familiar landmarks — sits at the edge ofthe Middle Fork of Beargrass Creek.51997-98 MSD ANNUAL REPORT


BEARGRASS CREEK WATERSHEDPurplePhaceliaPhaceliabipinnatifidaThe Beargrass Creek Watershed represents a sampling ofpractically every water quality problem that can be imagined,including: combined and sanitary sewer overflows; packagewastewater treatment plants; septic tank seepage; urbanstormwater run-off (non-point source pollution fromstreets, lawns and parking lots); erosion and sedimentationproblems; and flood management. The entire watershed,including the piped sections in the City of Louisville, receivesstormwater and wastewater flow from residential, commercialand industrial customers. Approximately three miles ofthe open sections of the creek were piped or channelizedfrom the 1930s to the 1960s.During the past 20 years, most of thepackage wastewater treatment plantsalong Beargrass Creek have been removedby MSD trunk sewer construction. Thesame trunk sewers have also eliminated almost all the septic tanks in thewatershed, although a few still exist.Future water quality initiatives in the watershed will focus on combined sewer andsanitary sewer overflows; flooding; non-point sources pollution and natural streamcorridor restoration. There are currently 63 combined sewer overflows andapproximately 32 sanitary sewer overflows in the Beargrass Creek Watershed. Withmore than 80 miles of open drainage channel, creeks and smaller tributaries, theaccess of non-point source pollution in the form of storm run-off is almost endless.TOP RIGHT: Workers wrestle aconcrete junction casting intoplace at the site of the newcombined sewer overflowtreatment facility on the SouthFork of Beargrass Creek, alongNewburg Road across fromBellarmine College.ABOVE: Beargrass CreekWatershed team leader, LoyisoMelisizwe, inspects the newGreenway walk along the mainstem of Beargrass Creek, justsouth of Upper River Road. TheGreenway provides a tranquilnatural setting in the midst ofthe city.These issues will be harder to address; will take longer to correct; and will cost more. For instance,petroleum products that are deposited on roadways and parking lots will be much more difficultto collect and treat than the flow from a single pipe to a treatment plant. In addition, the use ofherbicides and fertilizers isgrowing and increasing thenegative impact on streamquality and aquatic life. Correctingthese problems must beginwith public education andparticipation in identifying themost cost-effective solutions.THE BEARGRASS CREEK WATERSHED TEAM: Left to right — Blaine Dargavel,Travis Shepard, Jackie Jones, Roy Flynn, Clinton Smith, LoyisoMelisizwe, Troy Smith, Joe Eigel, Mike Holley, Carolyn Williams,Cathy Cornish, Raymond Jefferies, Craig Jones and Ron Henderson.61997-98 MSD ANNUAL REPORT
