Shade Ball Implementation in California

The implementation of shade balls in California was a significant step towards addressing the state’s severe drought conditions. The shade balls, essentially black plastic spheres, were deployed in a large-scale effort to reduce water evaporation from a major reservoir.

The Reservoir and Shade Ball Deployment

The shade balls were deployed in the Los Angeles’s main reservoir, the Los Angeles Aqueduct. This reservoir, known as Lake Arrowhead, was chosen due to its large surface area and its crucial role in supplying water to the region. The massive scale of the project involved the release of 96 million shade balls into the reservoir. This immense number of shade balls was intended to cover the entire surface of the reservoir, effectively creating a giant, floating shade.

The Release Method

The shade balls were released into the reservoir using a unique and efficient method. They were transported to the reservoir in large, specialized trucks. Each truck carried thousands of shade balls, which were then poured directly into the water. The release process was carefully orchestrated to ensure that the shade balls were evenly distributed across the surface of the reservoir.

Benefits of Shade Balls

Shade balls, floating, black, plastic spheres, offer a range of benefits for water reservoirs, particularly in the context of drought management. Their primary function is to reduce water evaporation, but their impact extends to improving water quality and reducing operational costs.

Reduced Water Evaporation

Shade balls act as a barrier against sunlight, preventing it from reaching the water’s surface. This significantly reduces the rate of evaporation, a crucial factor in conserving water, especially during periods of drought.

A study by the Los Angeles Department of Water and Power (LADWP) found that shade balls reduced evaporation by 85% in the city’s largest reservoir, the Ivanhoe Reservoir.

The reduced evaporation translates to significant water savings, allowing for a more efficient use of available water resources.

Improved Water Quality

Shade balls also play a role in maintaining water quality. By blocking sunlight, they inhibit the growth of algae, which can negatively impact water quality. Algae blooms can release toxins into the water, making it unsafe for drinking or recreational use.

The LADWP study noted a significant reduction in algae growth after the implementation of shade balls in Ivanhoe Reservoir.

This reduction in algae growth contributes to a healthier and more sustainable water supply.

Cost Savings

The implementation of shade balls can lead to substantial cost savings. The reduced evaporation translates to lower water treatment costs, as less water needs to be treated.

The LADWP estimated that the shade balls at Ivanhoe Reservoir would save the city $25 million in water treatment costs over a 10-year period.

Furthermore, the use of shade balls can also reduce the need for expensive and energy-intensive water augmentation measures, such as desalination, further contributing to cost savings.
