A. Buoy Locations and Design. The parks and recreation director, in accordance with regulations established by the park board, is authorized and directed to designate locations in the water areas of Silver Lake when and where safety buoys are reasonably necessary for the public safety, welfare, health and peace. The designated locations of safety buoys shall be determined upon taking into consideration hazardous conditions such as shallow water, rocks or snags, population at and about the lake, time and location of pleasure boating, swimming, bathing, fishing, diving and other water uses upon said lake.

Safety buoy location designations when located upon a map and approved by the park board shall establish the boundaries of speed control areas; swimmer only, or swimmer restricted areas; vessel prohibited, or vessel-type restricted areas; or other water use restriction zones within the lake. Such boundaries shall become effective when the buoys, as designated, are installed.

The parks and recreation director is authorized and directed to design buoys to accomplish the contemplated regulatory purposes in accordance with the State Uniform Waterway Marking System. Designs when approved by the city shall become the standard for construction for use in any lake in the city.

B. Signs or Other Signaling Devices. The director of parks and recreation, consistent with regulations adopted by the park board, may install such signs and signaling devices as will properly apprise water users of the water use regulation. It shall be deemed sufficient notice for any sign bearing general information to be placed only at the points of public access in Silver Lake where they shall be visible from both shore and water.

C. Privately Installed Water Use Regulation Equipment—Diving Flags. Individuals may maintain divers’ flags which shall be used only in the manner and at such places as are authorized by this chapter. A diver’s flag shall be a red flag, five units of measurement on the hoist by six units of measurement on the fly, with a white stripe having a width of one unit of measurement crossing the red diagonally. The flag shall have a stiffener to make it stand out from the pole or mast. A unit of measurement shall be not less than two inches. (Ord. 1183-85 § 5, 1985.)
