Main 3-4 Rouge Storm Water Management Area

Hydrology.  At the one Main 3-4 stream gage at Plymouth Road (US7), the mean streamflow recorded in 2002 was the lowest recorded since 1994 and was 54 percent of the 1994 through 2001 average.  The mean streamflow during the 2000 monitoring period remained the highest recorded since 1994.  In the Main since 1994, 2000 remained the wettest season on record and 2002 was the driest season on record.  The precipitation total in 2002 was 73 percent of the long-term average precipitation total for 1994 through 2001.     





Water Quality.  Continuous DO and water temperature monitoring was conducted at Plymouth Road (US7) and Rotunda Drive (US8) in 2002.  Plymouth Road (US7) has been monitored continuously since 1994 and continuous monitoring at Rotunda Drive (US8) began in 2001.  DO concentrations in the Main 3-4 SWMA have typically been poor since 1994 with the DO frequently dropping below the State water quality standard of 5 mg/L, particularly during warm summer months.  Trend analysis indicates that conditions are steadily improving at Plymouth Road (US7) during both wet and dry weather conditions.  In 2002, 73 percent of the recorded DO at Plymouth Road (US7) and 89 percent at Rotunda Drive (US8) met the 5 mg/L State standard.  Continuous temperature monitoring did not exceed a maximum temperature of 29.4°C (85°F). 





E. coli.  In general, E. coli bacteria levels have been poor in the Main 3-4 where a substantial percentage of measurements taken since 1994 have been above the State water quality standards for both total and partial body contact recreation.  Overall, concentrations of E. coli bacteria are improving in the Main 3-4 with the possible exception of the three most downstream locations.  Conditions at the three sites directly downstream of the Puritan Fenkell retention treatment basin (RTB) have shown substantial improvement during wet weather.  Generally, although improving, bacteria levels are still not meeting State water quality standards for partial body contact recreation of 1000 cfu/100 ml.
