- This hydrology predicts the Powell water surface elevation to. fall below the minimum power pool elevation of 3490 feet by 2006 and to remain or fall below. power pool in 10 of the next 17 years. It also indicates on three occasions the water surface is. just at or near the dead pool elevation of 3370 feet.

- USPA Raises Minimum Deployment Altitude by Ed Scott One of the actions arising from last week’s meeting of the USPA Board will raise the minimum deployment altitude for C- and D-license holders in the Basic Safety Requirements from the current 2,000 feet to 2,500 feet. The board had discussed this idea at previous meetings, and it has now come to the conclusion that the change will save lives.

- focuses on the acceptable level of phosphates in pool water to minimize algae. growth. Several vendors of phosphate remover products state that the maximum level. should be 125 ppb (parts per billion) or .125 ppm (parts per million). Others state that. phosphates are not a concern until they exceed 1000 ppb or even higher.

- Swim while chlorine levels are still at safe levels. Swimming helps lower chlorine, but only try this if chlorine is at slightly high (4 ppm). Experts disagree on how much chlorine is dangerous to swimmers. Public pools often shut down at 10ppm, while some pools use a 5ppm limit to be extra safe.

How Do Swimming Touch Pads Work? Touch pads must be installed in the middle of the lanes and must be 0.3 meters above and 0.6 meters below the surface of the water. This equates to 11.81 inches above and 23.62 inches below the surface. The pads must not have sharp edges and must have a .25-inch, or 9.84-inch, black border.

Swimming Pool Dimensions The cross line on the + should be 0.5 meters (1.6 feet) long and 0.3 meters (1 foot) below the surface of the water. Similarly, a line down the middle of the lane — ending in a “T” at each wall — is often along the bottom of the pool. Each T stops 1.6 meters (5.3 feet) from the wall.

- Maintaining proper pH levels. pH Level is the acid/base content of water. The pH scale ranges from 0 to 14 with 7 being neutral. Ideally you should strive to maintain pH levels between 7.2 and 7.6 in order to prevent eye/skin irritation, pool surface and equipment damage. Total alkalinity is the measure of certain minerals in the water. These minerals act as buffering agents and allow you to readily control your pH.
