On account of the much larger size of the watershed, however, only the larger streams were tested. The results of the analyses are given in the tables appended to this report. Suspended Matter--The samples collected on June 19th were all turbid on account of the heavy rainfall that occurred two days before, as the following figures show: SUSPENDED MATTER IN SAMPLES OF WATER FROM THE GUNPOWDER SUPPLY. The turbidities of the samples collected in the upper portion of the watershed near Whitehall were higher than those collected from some of the smaller feeders further south, indicating, what seems to be a general fact, that the smaller streams clear up more rapidly after a rain than the larger streams. On June 19th there was a general increase in the turbidity of the water downstream. Thus, the Little Falls branch at Whitehall had a turbidity of 80; the West Branch, near Whitehall. 90; the Gunpowder River below Phoenix. 110; the Gunpowder River above Warren, 120, and the Loch Raven Reservoir at the flam, 280. On July 7th, after several days of dry weather, this same increase in turbidity downstream was noticed, but the figures were all materially lower, ranging from 4 and 5 at Whitehall to 55 at the Loch Raven Dam.
