5 Colo. Code Regs. § 1003-5-3.1
Spas will be a maximum of four (4) feet deep. Wading pools will be a maximum of eighteen (18) inches deep in the center and twelve (12) inches at the sidewalls. The public pool shall be designed and constructed so that efficient and safe control of the area and bathers can be accomplished and so that the recirculation of water in the pool is not impeded. The slope of the bottom of any portion of the pool having a water depth of less than five (5) feet shall not be more than one (1) foot in twelve (12) feet and said slope shall be uniform.
In portions at the break where the shallow end (water five (5) feet deep or less) goes into to the deep end of the pool, the slope shall not exceed one (1) foot in three (3) feet. Walls of a pool shall be either (a) vertical for water depths of at least six (6) feet or (b) vertical for a distance of three (3) feet below the water level below which the wall may curve to the bottom.
Depth markers shall be a minimum of four (4) inch numerals in a contrasting color on the deck, and four (4) inch numerals in a contrasting color on the vertical wall at or above water level. The dimensions of the pool in the diving area shall conform to the following table. (This drawing does not show shallow portions of the pool.)
Note: L4 Is a minimum dimension to allow sufficient length opposite the board. This may of course be lengthened to form the shallow portion of the pool.

L1, L3, L4, combined represent the minimum distance from the tip of board to pool wall opposite diving equipment.
At least fifteen (15) feet of free and unobstructed head room including free from electrical wires and fixtures, shall be provided above diving boards. Horizontal separation of ten (10) feet shall be provided between the center line of diving boards and side walls except this may be reduced to eight (8) feet for surface boards less than 1/2 meter above water surface.
The minimum depth of water in areas dedicated for competitive events shall be four (4) feet. Attached wading areas shall be separated from the main pool(s) by a safety barrier or buoy line attached to the side walls. Separate wading pools shall be completely fenced with a three (3) foot high fence.
