Join the Ciudad Soil and Water Conservation District for the Rolling River Presentations at the Los Ranchos Growers' Market on Saturday, November 9 with live demonstrations at 9:30am & 11:00am of watershed action. The Rolling River is a working model of a watershed, mounted on a trailer that is transported to schools and special events. The trailer is filled with sand-like recycled plastic that can be molded into nearly any type of landscape and outfitted with miniature forests, farms, and cities. Hidden plumbing allows the rivers to actually flow, wetlands to appear, and lakes to rise and fall in response to simulated flood and drought cycles. The Ciudad Soil & Water Conservation District uses their Rolling River to demonstrate a variety of environmental concepts while illustrating the special challenges faced in very ‘urban’ watersheds.
