Great Salt Lake's brine shrimp population booms, majorly impacting future of Utah, wildlife, and the

Brine shrimp, a crustacean native to the Great Salt Lake and recently named the official state crustacean, has seen an incredible population growth over the last year, symbolizing hope for the Great Salt Lake and serving as evidence of the state's efforts to improve the lake's health.

So they aren’t SEA monkeys, they are lake monkeys?
I’m devastated

[deannelson]

Yeah it definitely had everything to do with the new water control measures they put in and nothing to do with the gigantic flush of new water from the massive snowpack last year!

[oneanddonetzone]

Move over crazy cat lady… The Brine shrimp lady is in town!

something you might not have heard... the the sand at the Great salt lake is actually the one little bone brine shrimp have
do you know you can take dry "sand" from the shore ... their put a flower in a jar cover it with the "sand" and it will suck the moisture out of the flower and preserve it permanently forever

Oh ugh, I remember when I was a kid that the dead brine shrimp would float to the top and it would stink up Salt Lake City something awful.

[BillGreen]

Darn kid setting their sea-monkeys free in the lake. Now look what you've done.

[blueabattoir]

Brine Shrimp will achieve sentience on March 15, 2024. You have been warned.

Not only cysts but high-quality cysts.

This was a typical knee-jerk reaction to the record flooding of 1983 (Glen Canyon Dam was nearly lost). A 'solution' was found by 'experts.' This is happening today, too. 'Solutions' to completely normal 'problems' that the short-sighted use to 'correct' nature. Carbon is natural, pollution is not. But climate change:

Great Salt Lake is split into a north arm and south arm by a railroad causeway. The two arms have differing color, chemistry, biology, and lake surface elevation (see article by J.W. Gwynn in Survey Notes, 2002, v. 34, no. 1, p. 1). The history of this disunion begins with a railroad shortcut, followed by periodic construction projects necessitated by the dynamic character of Great Salt Lake. A feature associated with the railroad causeway, known as the boxcar seawall, is an intriguing piece of this story.

An outstanding feat of American railroad engineering is the 102-mile-long Southern Pacific Railroad Lucin Cutoff stretching from Ogden to Lucin, Utah. It bypassed the circuitous 1869 Promontory Summit route, where the Golden Spike was hammered, by going straight across Great Salt Lake. The Lucin Cutoff took just over two years to construct and was fully operational by 1904. The segment crossing the open waters of Great Salt Lake was the most challenging, including more than 8 miles across Bear River Bay and more than 20 miles from the Saline railroad siding to the Lakeside settlement.

The original Lucin Cutoff included three rock embankments constructed in the lake: the Bagley Fill across Bear River Bay, the Rambo Fill on the westernmost side at Lakeside, and the Saline Fill at the southern end of the Promontory Mountains, all totaling nearly 15 miles. The 12 miles between the Rambo and Saline Fills was spanned with the longest wooden trestle bridge in the world, now dismantled and reclaimed. Fifty years after construction, the deteriorating trestle required extensive upkeep and an expensive overhaul loomed.

Because rail traffic could not be disrupted, the idea of restoration was abandoned in favor of sidestepping the trestle with a solid-fill causeway to be placed 1500 feet north of and parallel to the trestle, connecting the Rambo and Saline Fills. The causeway took three years to build and was completed in 1959. The amount of material handled was nearly a third of that excavated for the Panama Canal.

A year after completion, the causeway had sunk about a foot into the soft sediments of the lakebed, and nine years later had sunk 3 more feet. It continued sinking a few inches each year thereafter. The diminishing freeboard, or distance between the lake level and the top of the causeway, was not an immediate concern because the lake level remained low, at least for the first two decades after construction. Then, from October 1981 to April 1987, the lake rose more than 13 feet, to nearly 4212 feet above sea level, a high not seen in more than a century.

Storms over Great Salt Lake can generate waves greater than 8 feet in height, and due to the high salinity of the water, the waves are denser and have higher energy than ocean waves. Storms can also produce a storm surge on the lake, pushing the water against the shore or causeway and, in effect, raise the lake level 1 or 2 feet. By 1983, waves began to overtop the causeway, scouring and eroding the protective riprap.

A prompt solution was required, so it was decided that the best initial step to maintaining the causeway was a “boxcar seawall” to act as a breakwater. The seawall was intended to defend the north side of the causeway, which bears the most intense impact from storm waves.

In August and September of 1983, the Southern Pacific Company placed 1430 surplus boxcars, hopper cars, and gondolas (low-sided, open-topped cars) along the edge of the embankment, creating a barrier between the causeway and lake. The wheel and axle assemblies were removed from the cars, and the ends of the roofs were cut out leaving only a center strip in the middle third. The cars were placed end-to-end in a shallow ditch between the causeway and a small berm and then filled with quarried rock.

Raising the elevation of the entire causeway began the same year the seawall was built and continued until 1987, requiring millions of tons of stone. Crushed limestone was used to raise the causeway more than flush with the top of the boxcars, as much as 10 feet in places. The remainder of the seawall was concealed with boulders weighing one ton or more, dubbed “armor stone, ” to shield the causeway from erosion.

The boxcar seawall provided crucial protection during the time needed to raise the causeway, sheltering it for years and easing disruptions to train traffic, even as the lake continued its rapid rise. The seawall signifies yet another large-scale engineering success in the challenging and enduring history of the path across Great Salt Lake.

Sea Monkey's yes those things are so cool. here in California we have them in Mono Lake. thanks for sharing...

[bobhaugland]

So if brine shrimp are the only thing that can live in the Great Salt Lake, what do they eat?

[tstahler]

Note to self, buy sea monkey stock! 😂

[MileDesertRat]

Is there a correlation between brine shrimp, seagulls, grasshoppers, and Mormons?

[emanuelcarr]

Utah is doing some amazing things right now! Keep up the outstanding work over there!

[thelastdefenderofcamelot]

I failed to hatch mine. Not sure where I went wrong.

[Navitus]

The lady on the left was so enthusiastic about this topic that was great.

[filiplaskovski]

Looks like this is where the brine shrimp eggs come from :)

[Mambo]

They fr just take all the eggs out the lake and then sell them…

[mm-ytsf]

never thought i'd hear "high quality cysts"

[jamiegallier]

Surprise! Animals thrive better in the environments they evolved in.
