Spring calving is nearly complete, and livestock producers continue to be concerned about stock water supplies. Topsoil moisture supplies were rated 17 percent very short, 29 percent short, 51 percent adequate, and 3 percent surplus. Subsoil moisture supplies were rated 38 percent very short, 39 percent short, 22 percent adequate, and 1 percent surplus. Producers averaged 4.6 days suitable for fieldwork last week.
