1 The area of the Sudbury watershed used in making up these records included water surfaces amounting to 1.9 per cent. of the whole area from 1875 to 1878,
inclusive, and subsequently increased by the construction of storage reservoirs to 3.0 per cent. in 1879, 3.4 per cent. in 1885, 3.9 per cent. in 1894 and 6.5 per cent.
in 1898. The watershed also contains extensive areas of swampy land, which, though covered with water at times, are not included in the above percentages of
water surfaces.
