in this study were also much lower than typical urban area runoff coefficients which range from 0.2 to 0.7 for residential and commercial areas respectively, and are in fact comparable to those estimated for undeveloped areas. The small runoff rates from the golf courses is probably a function of the management practices on the golf courses which promote rainfall infiltration. These practices include regular soil aeration, addition of organic matter, maintenance of vigorous turf grovrth. In addition, golf courses do not have the severely compacted subsoil which is typical of many urban lawns. Although base flow did occur at all of the sites during the study period, it was negligible except at the Minikahda Club. The 1168 acre watershed above the course delivered over 564 acre-feet of water to the course, over half during non-rainfall periods. The watershed contains a large wetland complex upstream of the golf course. The wetlands apparently store water and release it after stormwater flows have abated. NUTRIENT AND PHYSICAL PARAMETERS A total of 67 rainfall runoff samples from the four golf course:? were collected during the ice free season in 1994. More rainfall events were sampled at the Woodhill site, 19, than any of the other sites. The Woodhill site had the fewest problems with the sampling equipment. In addition, because the runoff water entered a large pit where it was temporarily stored, adequate volume for collection was available during all sampled events. Conversely, at the other sites where samples were collected from an intermittent stream flow, the water depth in the conduit during small events was not sufficient to cover the intake strainer. As a result, only a few milliliters of water were collected, an amount insufficient for analysis. The fewest events, 11, were sampled at the Minikahda inflow site, mainly because of problems with the sampling equipment. The mean, median, range, and standard deviation of the parameters found in the runoff water are shown on Table 6. As the table shows, there was a wide range in the concentration of most parameters during the study period. For example the total phosphorus concentration ranged from 0.08 mg/I to 3.1 mg/I, and the total Kjeldahl nitrogen concentration ranged from 0.50 mg/I to 8.2 mg/I. The mean concentrations of total phosphorus, soluble reactive phosphorus, total Kjeldahl nitrogen, and nitrate & nitrite nitrogen from the golf course sites were higher than concentrations reported for urban residential or commercial areas (Brach, 1989). .However, the concentration of total suspended solids was lower. The mean concentrations of total phosphorus and soluble reactive phosphorus, 0.52 and 0.34 respectively, were significantly different (p<0.05). In addition, the sum of the ammonia nitrogen and the nitrate & nitrite concentrations were significantly less than
