Can Bubble Wrap Save Water? Examining the Potential of Covering Lake Mead to Reduce Evaporation

Lake Mead, located on the Colorado River, is one of the largest reservoirs in the United States. It provides water for millions of people in the southwestern part of the country. However, due to a combination of factors including drought, climate change, and increased demand for water, the lake has been experiencing declining water levels. One of the major contributors to water loss is evaporation, which accounts for about 30% of the lake’s water loss. As a result, there have been proposals to cover part of the lake with large sheets of bubble wrap to reduce evaporation.

The science behind evaporation

Evaporation is the process by which water is converted to water vapor and released into the atmosphere. The rate of evaporation depends on several factors, including temperature, humidity, wind speed, and the surface area of the water. The higher the temperature and wind speed and the lower the humidity, the higher the rate of evaporation. On the other hand, the greater the surface area of the water, the greater the amount of water lost to evaporation.

The Idea of Covering Lake Mead with Bubble Wrap

The idea of covering part of Lake Mead with bubble wrap to reduce evaporation is based on the principle of reducing the surface area of water exposed to the atmosphere. By covering a portion of the lake with bubble wrap, the amount of water exposed to the atmosphere would be reduced, thereby reducing the rate of evaporation. The bubble wrap would also act as an insulator, reducing the amount of heat transferred from the water to the atmosphere, which would further reduce the rate of evaporation.

However, there are several challenges associated with this proposal. One of the biggest challenges is the cost of covering such a large area of the lake with bubble wrap. Another challenge is the effect of the bubble wrap on the lake’s ecosystem. The bubble wrap could potentially block sunlight from reaching the water, which could negatively affect the growth of aquatic plants and the survival of fish species.

Previous studies on covering water bodies with bubble wrap

The idea of covering bodies of water with bubble wrap to reduce evaporation is not new. Several studies have been conducted in the past to test the effectiveness of this approach. One such study was conducted by researchers at the University of California, Berkeley, who covered a small pond with bubble wrap and observed a 50% reduction in evaporation. Another study conducted in Australia showed that covering a small reservoir with bubble wrap reduced evaporation by 30%.

However, it is important to note that these studies were conducted on small bodies of water, and the effectiveness of this approach on a large body of water such as Lake Mead is still uncertain. In addition, the cost and environmental impact of covering such a large area of the lake with bubble wrap would need to be carefully considered before implementing this proposal.

Conclusion

In conclusion, covering a portion of Lake Mead with large sheets of bubble wrap could potentially reduce the amount of water lost to evaporation. However, the effectiveness of this approach on a large body of water is uncertain, and the costs and environmental impacts would need to be carefully considered before implementing this proposal. There are also other approaches to reducing evaporation, such as increasing water depth, using chemical treatments, and implementing water conservation measures.
