SILVERTHORNE, Colo. (AP) - High waters have prompted the closure of parts of Blue River in Summit County.
Silverthorne authorities closed part of the river indefinitely for recreational watercraft near Silverthorne.
The closure does not affect kayakers, but police strongly urged them to avoid bridges because of possible low clearance.
Silverthorne Police Chief Mark Hanschmidt tells the Summit Daily News there have been "several close calls" with recreational watercraft.
Warning signs have been placed at river access locations. The river remains open north of Silverthorne, but officials said only experienced boaters and rafters should enter the river because of high flows.
Denver Water on Friday said it might not be able to prevent flooding on the Blue River below Dillon Reservoir as high mountain snowpack continues to melt.
