surface inlet “beehive” was installed adjacent to the existing manhole in the low area. The two manhole structures were connected by 12 feet of 12 inch PVC pipe installed at a slope of 1.0 %. The flow line of the 12 inch pipe was installed 30 inches above the flow line of the 24 inch drain pipe to minimize backflow. The area was graded to divert water Into the new manhole, after which the former catch basin was sealed up. MEADOWBROOK GOLF COURSE The sample station at the Meadowbrook Golf Course was established near the discharge end of the 12 inch concrete drainage pipe which bisects the course. Runoff from 93.7 acres of the golf course drained through the concrete pipe above the sample station, (Table 1). The concrete pipe was used as the primary measuring device to estimate water flow. WOODHILL COUNTRY CLUB The sample station for the Woodhill Country Club was installed in the pumping station at the south edge of the course. Approximately 30 acres of the course drain to the lift station, (Table 1). The pumping station consisted of a 83 inch x 142 inch x 82 inch deep concrete pit, into which a 3 horsepower pump was installed to lift water into a 6 inch discharge line. The pump was equipped with a float system to start and stop the pump at predetermined water level changes. A tipping bucket rain gauge was installed on the site to trigger the sampler during rainfall events. The data logger was set to initiate the sampler with a minimum of 0.1 inches of rainfall In a 5 minute interval. MINIKAHDA CLUB Two sample sites were established at the Minikahda Club, one at the discharge end of a 36 inch corrugated metal pipe at the north end of the course to determine the quality and quantity of the water entering the golf course from the 1168 acre watershed upstream of the course. A second station was established in a driveway culvert 50 feet from the dowrisream end of the golf course property, where the open channel reenters the storm sewer system. This station was established to determine the quantity and quality of runoff leaving the golf course. The downstream site received runoff from 137 acres of the course (Table 1). 8
