The Park staff has drawn down the water level on Olson Lake at Rock Cut SP. There is now a ring of mudflats around the lake, and the east end is all mud, with some low wet spots here and there. Yesterday, 10/12, I found 4 White-rumped Sandpipers, 6 Wilson’s Snipe, 2 Pectoral Sandpipers, and 1 Lesser Yellowlegs, plus nearly 40 Killdeer. There were also 3 American Pipits on the mudflats.
There are still shorebirds moving through, so we should keep an eye on Olson Lake to see what might show up.
