3. DRAINAGE NETWORKAs with many of Ontario's small agricultural watersheds, the Avon basin has had anintensive history of drainage engineering particularly in the early part of this century. Infact the main channel below Stratford is virtually the only remaining natural water course.The tributaries and that portion of the Avon River above Stratford have all beenchannelized at some time in the past.As can be seen from drainage intensity figures in Table 3, the greatest rural drainageintensity is found in the lower basin where poorly drained soils are found.Owing to the presence of storm sewers, the developed urban area is by far the mostintensely drained area in the basin. As a result, the urban area seems to contribute adisproportionately large amount of baseflow to the river. For example, the 1980 summerbaseflow at station 10 (Federal flow gauge - GD018) was estimated to be 0.35 m 3 sec -1(12.5 ft. 3 /sec.). In contrast, the estimated dry weather storm sewer flow for Stratford was0.10 m 3 sec -1 (3 .5 ft. 3 /s) and the sanitary effluent flow was 0.20 m 3 sec -1 (7.0 ft. 3 /s).* Thisimplies that the rural area above station 10, comprising 12,233 ha.(30,228 acres), yieldedonly 0.05 m 3 sec -1 (1.8 ft. 3 /s) during dry weather episodes.___________________* Characterization of Urban Dry Weather Loadings, SAREMP Technical Report U-3 (SeeSection 5.
