Crews use an excavator transfer to maneuver stones close to the Nice Salt Lake Causeway to lift the berm by 4 toes in July 2022. Gov. Spencer Cox ordered Friday that the berm be raised one other 5 toes to assist with rising salinity considerations. Utah Division of Forestry, Hearth and State Lands
Utah Gov. Spencer Cox signed a brand new government order Friday, calling on the Utah Division of Forestry, Hearth and State Lands to lift the Nice Salt Lake causeway berm by 5 toes, in an effort to enhance salinity situations which are "threatening the Nice Salt Lake ecosystem."
The order particularly calls on the division to lift the berm, which is situated by a 180-foot breach within the causeway — from 4,187 toes to 4,192 toes — in an effort to cease the rising salinity ranges within the southern arm of the lake. The division had already raised the berm by 4 toes final 12 months due to this problem.

"The Nice Salt Lake is essential to our surroundings, ecology and economic system and we should do every thing we will to guard it," Cox mentioned in a press release Friday. "We have been blessed with vital snowpack to this point this winter, and this government order will enable the state to maneuver shortly to extend the lake degree within the south arm by capturing spring runoff. We do not need to miss this chance to safeguard the lake."
The order additionally calls on the Utah Division of Pure Sources and the Utah Division of Environmental High quality to organize a berm administration plan to information future changes to berm peak. The order is ready to run out as soon as the plan is adopted and carried out.
Kim Wells, a spokeswoman for the Utah Division of Pure Sources, defined that it is a "fairly straightforward course of" to lift the berm, which she mentioned is anticipated to occur inside the subsequent week. She added that the timing of Friday's order comes at an essential time within the Nice Salt Lake ecosystem.
Brine shrimp cysts start to hatch within the spring, enjoying an important position within the ecosystem. They're thought-about a "helpful meals supply" for the ten million migratory birds that journey via the lake yearly, in accordance with the Utah Division of Wildlife Sources. The division additionally notes that brine shrimp are additionally helpful to the economic system when they're harvested on the finish of yearly.
However brine shrimp must have the proper situations to thrive.
"Balancing out that salinity is crucial proper now," Wells mentioned. "In order that's precisely what we're attempting to — simply seize every thing we will to stability that salinity and guarantee that we're defending the ecosystem."
Elevating the berm close to the causeway is without doubt one of the early options to a rising downside with the drying lake. The Nice Salt Lake reached a brand new all-time low lake degree final 12 months, and specialists mentioned that the southern arm has gotten saltier because the lake shrinks.
The southern arm is often much less salty as a result of water from the Jordan, Bear, Ogden and Weber rivers movement into it. One attainable motive for the change is that the northern arm's water is heavier and is pushing larger concentrations of salt into the southern arm, division officers mentioned final 12 months.
Crews raised the berm in an effort to cease the northern arm's impression, and restore the traditional stability of salinity between the 2 arms. That is what is occurring once more lower than a 12 months later.
Wells mentioned it is unclear how lengthy it's going to take to see any advantages from the emergency measure. Nevertheless, they may increase the berm forward of this 12 months's spring runoff, which is anticipated to be a lot better than final 12 months's or the 12 months earlier than due to a stronger snowpack on high of wetter soil moisture.
"We're simply attempting to seize these freshwater inflows coming in and we're attempting to maximise the advantages of the spring runoff within the south arm," she mentioned. "We have had an amazing snowpack this 12 months, we're reaping the advantages of water, and if we go away the berm on the elevation it's now, we're shedding that water to the north arm and we're not in a position to seize the advantages of that spring runoff."
