Aquatic weeds and water delivery are typically not a good combination. When weeds are growing in CAP’s 336-mile closed system, they tend to slow water flow by causing excess friction. When the vegetation dies, it floats to the surface and eventually restricts water flow to the pumps by clogging the trash racks. If our rake systems can’t keep up, the pumps will shut down due to vibration, cavitation, or just a lack of water. In many water conveyance systems, drying out the canal or using a good dose of aquatic herbicide is used to control or eliminate weed growth. However, CAP delivers water to municipal and agricultural customers 365 days a year, so drying out the canal isn’t possible and chemical treatment can’t be used. So at CAP, we invite a special guest to the salad bar!
