In October, volunteers planted 1500 Peacock Larkspur bulbs in the Corvallis Watershed. All were planted across the watershed road from Shiver River property. Shiver River’s boundary with the City doesn’t follow the watershed road all of the way to the water treatment plant. It parallels the road in some places, but is in the middle of some dense underbrush and trees.
