DREDGING
Dredging is the process of removing sediments and silt from the bottom of a body of water. Dredging Utah Lake will deepen the lake, remove nutrient-loaded sediments, and create clearer, cleaner water.
WHAT WILL WE ACHIEVE?
DEEPEN AVERAGE
DEPTH 3-6 FEET
SHAPE UNDERWATER TOPOGRAPHY (BATHYMETRY)
IMPROVE WATER TEMPERATURE AND CIRCULATION
INCREASE WATER HOLDING CAPACITY BY 405K FEET
WHY DREDGING?
For Utah Lake, dredging means removing the fine sediments from the top 8-12 inches of the lake bottom and removing nutrient-loaded sediments comprising 18-36 inches of lake bottom. Removing sediments will deepen the lake, reduce forces that can disturb the lake bottom, and change the underwater landscape to better circulate and cool the water.

HOW MUCH HAS TO GO? IT DEPENDS
By reducing surface area of the lake and removing invasive species, we can reduce water loss to save billions of gallons of water annually.
HOW MUCH HAS TO GO? IT DEPENDS.
The depth of dredging will vary in different parts of the lake based on engineering design and data from core samples. Some areas may be dredged by as little as 18 inches, while other areas may be dredged deeper to create deeper-water channels.
1 BILLION CUBIC YARDS TAKES TIME.
Current designs suggest that to deepen the lake to the desired levels, upwards of one billion cubic yards of material will be dredged. To maintain the lake’s water balance, we estimate that it will take approximately 12-15 years to move all the materials.

“The nation’s coastal, ocean, and freshwater resources are critical assets, which must be protected, conserved, and restored … Dredged material is a resource, and environmentally sound beneficial use of dredged material for such projects as wetland creation, beach nourishment, and development projects must be encouraged.”

DRIVEN BY SCIENCE.
POWERED BY PASSION.
We’re working with world-class scientists and engineers to save Utah Lake after more than 150 years of degradation. Our plans are informed by proven technology and data to ensure a responsible, sustainable path forward for the lake and surrounding area.
