WALLA WALLA, Wash. – A herd of goats arrives today, Friday, May 6, to remove weeds and other vegetation growing on levees that border the creek shoreline extending from the Mill Creek diversion dam downstream to the metal division works foot bridge near the Mill Creek Office. The first phase of grazing (about 400 goats) is planned for the south side of the Mill Creek channel near the diversion dam, across the creek from Rooks Park. The goats will be contained within electric fencing while working in the vegetation-maintenance zone, accompanied by professional herding dogs and shepherds.
