Many people believe Enchanted Lake is polluted and brings brown water to Kailua Bay when the sand berm at the beach park is opened. While brown water does flow through the lake, it is not the source of this sediment-laden water. Does it come from the wetland then? No, it is also just a conduit, although it does filter some of it out before it gets to the lake. So where does this brown water come from? All we need to do is follow the dirty water upstream.
- Olomana Heights home lots,
- Home construction sites along the Old Kalanianaole Highway with inadequate erosion controls.
- The City’s storm drain sinkhole repair project on Kanapuu Street.
From the settling basin, the water flows into the hardened culvert all the way to the Kaelepulu Wetland Bird Preserve, and quickly enters Enchanted Lake on its way to Kailua Beach.
