Cleaner, tastier lake water

NORMAN — A prototype oxygen infusion experiment at Lake Thunderbird could be a breakthrough for municipal water supplies throughout the country. The east Norman lake, the primary source of Norman’s water supply, is showing better oxygen dispersion in target areas.

That’s significant in that low oxygen levels lead to less decomposition of organic materials like phosphorous.

As the water cools in the fall, nutrient-rich water rises and feeds algae, which contributes to taste and odor problems as the lake “turns over.”

The experiment being carried out by the lake’s operators, the Central Oklahoma Master Conservancy District, was funded by federal stimulus dollars. If the results continue to be positive, the Supersaturated Dissolved Oxygen System, or SDOX, could be installed at reservoirs with similar quality issues.
