Here are a few photos showing views of buoys in the river drifting in the strong current.

Small buoys afloat at Bicentennial Park

A large amount of vegetation floats down the river and can accumulate on objects in the river, as it did on the anchor chain of a large buoy.

Buoy at East Spillway

The East Spillway is a secluded area up river where people like to gather. This is a problem because they often play with rocks in the shallow water—rocks that San Marcos Salamanders like to hide under. A buoy was added to advise visitors to: LEAVE ROCKS ALONE FOR CRITTERS THEY ARE HOMES. A Sally Salamander graphic wraps around the sides of the buoy.

Buoys in flood conditions

Heavy rains caused flooding that raised the river almost 5 feet—the buoys survived!
