Every Gallon Of Water Removed From The Ocean, Reduces The Ocean Level
Research shows us that to reduce the ocean water level by one inch will require 2 trillion gallons of water to be removed and moved inland. Each 10 x 10 square mile lakes, which are 20 feet deep will hold just over 400 billion gallons of water. Therefor each lake will drop the ocean water level by 0.2 of an inch. If 5 lakes were built each year, this would combat the ocean water level rising. Any faster construction would lower the ocean level.
The global average rate of sea level rise has been increasing, from 0.1 inches (2.5 millimeters) per year in 1993 to 0.13 inches (3.4 millimeters) per year as of 2022, based on satellite measurements. This rate is roughly twice as fast as the long-term trend. From 2006–2015, the rate was even faster, at 0.14 inches (3.6 millimeters) per year, which was 2.5 times the average rate from most of the 20th century. From 2013–2022, the rate accelerated further to 0.182 inches (4.62 millimeters) per year. This is the fastest rate of sea level rise in at least 3,000 years.
If enough lakes were built, we could lower the water level of the ocean, however a high level of care would need to be taken not to lower it by too much.
There is data to show that a small percentage of the coastal areas of the United States will be under water by 2050. This has been spoken about for years, but it s stating to become a reality. Inland lakes can stop this from happening.
There are plans to build large inland lakes in Australia, Africa and the Middle East. The level of the ocean can easily be lowered by several feet by this effort. Can will need to be taken to prevent ocean intake pipes, boat ramps etc. from becoming out of the water. An international plan to build over time will ensure that the ocean water level does not drop to rapidly.
Rivers discharging into the ocean will deposit fresh water further out into the ocean, so care will need to be taken not to upset the ecosystems due to this. Increased river harvesting will keep the current discharge rates after the oceans drop.
