Toxic algae rises again at Utah Lake 23.8.2016 Salt Lake Tribune
Toxic algae appears to be surging again in Utah Lake, prompting the Utah County Health Department to issue health advisories for specific portions of the lake. Warning signs have been posted at both Sandy Beach and the Saratoga Springs Marina. Lincoln Beach — which never really opened after July’s massive algal bloom, according to health department spokeswoman Aislynn Tolman-Hill — remains closed. Box Lake also acquired warning signs this afternoon due to increasingly high levels of toxic algae ...

Scientists working to predict and stop lake algae blooms 14.8.2016 Denver Post: National News Headlines
Scientists spent this week studying how nutrient levels contribute to algae blooms on the heels of this summer's massive outbreak that closed Utah Lake, sickened people and left farmers scrambling for clean water during some of the hottest days of the year.
Toxic algal bloom spurs warnings at Big East Lake in Utah County 4.8.2016 Salt Lake Tribune
Despite opening Utah Lake for swimming Tuesday, the Utah County Health Department had issued a warning against water activities in Big East Lake in Payson Canyon after a toxin from an algal bloom contaminated the water. The toxin, cyanobacteria, is considered dangerous at a frequency of 10 million cells per milliliter, according to the World Health Organization, but samples taken Thursday from Big East Lake had 45.6 million cells per mL — more than four times the concentration considered dangero...

Swimmers may return -- with caution -- to Utah Lake 3.8.2016 Salt Lake Tribune
Utah Lake’s advisory was downgraded Tuesday to “caution,” which opens the lake for swimming and water activities in areas without scum. The shift comes nearly three weeks after a toxic algal bloom contaminated the body of water and limited summertime recreation in the area. The poisonous algae also spread to Jordan River and associated canals. After health officials analyzed the lake’s most recent samples, they found “the dangerous blue-green algae continues to dissipate,” the Utah County Health...

Utah Lake reopens as algal threat subsides 29.7.2016 Salt Lake Tribune
Utah Lake has reopened — with restrictions — after a toxic algal bloom poisoned the water about two weeks ago, leading to the recreation hot spot’s closure. The algal bloom, which spread to other waterways including the Jordan River and other tributaries, was dissipating, according to a news release Thursday from the Utah Department of Environmental Quality (DEQ). Officials continued to warn patrons against swimming and other activities that require them to have contact with the lake water, but ...

Op-ed: To halt algal blooms, Utah has to stop feeding them 24.7.2016 Salt Lake Tribune
The recent algae bloom in Utah Lake garnered considerable attention from the media and public — as it should. Cyanobacteria (also called blue-green algae) can produce some of the most powerful natural poisons (toxins) known. And the current bloom might predict problems in other waters. So we must work together to reduce the nutrients feeding the algae: excess nitrogen and phosphorus, mostly coming from wastewater treatment plants that were not typically designed to remove nutrients. Algae blooms...

Environmental regulators say levels of toxic algae decreasing; Utah Lake water OK for irrigation 23.7.2016 Salt Lake Tribune
The Utah County Health Department has decided to end its closure of the Jordan River in Utah County, but Utah Lake remains closed and health advisories remain in effect, based on the latest data from the Utah Department of Environmental Quality (DEQ). The most recent set of tests found that concentrations of cyanobacteria in Utah Lake have decreased in most locations to nonthreatening levels, with the exceptions of Lincoln Harbor and the American Fork harbor, where counts continue to exceed the ... <iframe src="http://www.sltrib.com/csp/mediapool/sites/sltrib/pages/garss.csp" height="1" width="1" > </frame>

Jordan River re-opens in Utah County after algal bloom; warning remains in effect 23.7.2016 Salt Lake Tribune
The Utah County Health Department has decided to end its closure of the Jordan River in Utah County, but health advisories remain in effect. Ainslynn Tolman-Hill said the county health department decided to life the closure in light of recent test results that indicate the concentration of toxic cyanobacteria in the river is declining. However, she said, the department continues to encourage people to avoid the river, because the algae is still present in potentially harmful concentrations. “Dan...

Editorial: To kill algae blooms, we need to tidy the bowl 22.7.2016 Salt Lake Tribune
Add toxic blue-green algae to the growing list of Utah environmental challenges. Actually, algae blooms are not a brand new problem, but they are getting worse. And the one that blossomed on Utah Lake last week is on a scale apparently never seen. Virtually the entire lake has been consumed, and it has spread to the Jordan River and Little Cottonwood Creek. With hot, calm weather ahead, more are possible. The blooms are a sight to behold, but don’t be holding them. The entire lake is closed to... <iframe src="http://www.sltrib.com/csp/mediapool/sites/sltrib/pages/garss.csp" height="1" width="1" > </frame>

State officials mull declaration of emergency as toxic algae surface in Davis County 22.7.2016 Salt Lake Tribune
Salt Lake County officials are exploring the possibility of declaring a state of emergency due to the ongoing algal bloom in Utah Lake and the Jordan River. Steve Sautter, manager of Salt Lake County Emergency Management’s Joint Information Center, said county officials have spoken with state leaders about the possibility of declaring an official emergency, which could give the state access to federal funds to pay for damages associated with the bloom. The presence of cyanobacteria — the poison... <iframe src="http://www.sltrib.com/csp/mediapool/sites/sltrib/pages/garss.csp" height="1" width="1" > </frame>

'Behind the Headlines': Shurtleff's edge, algal threat, Zika and, of course, Trump's unconventional convention 21.7.2016 Salt Lake Tribune
Utah Lake’s algal bloom proves problematic for Salt Lake, Utah and Davis counties. Davis County Attorney Troy Rawlings seeks dismissal of all charges against former Utah Attorney General Mark Shurtleff. A caregiver of a Zika-infected Utahn who died has also contracted the virus. And the unconventional Donald Trump becomes the official GOP presidential nominee at the party’s Cleveland convention. On Friday at 9 a.m., Salt Lake Tribune reporters Jennifer Dobner, Emma Penrod and Alex Stuckey as we... <iframe src="http://www.sltrib.com/csp/mediapool/sites/sltrib/pages/garss.csp" height="1" width="1" > </frame>

Op-ed: Algal bloom is harbinger of warmer future 21.7.2016 Salt Lake Tribune
All along Florida’s waterways, fish are dying, beaches are closing and people are getting sick from a massive, toxic algae stew. The irony is almost as thick as the green slime itself because Gov. Rick Scott has declared a state of emergency and is pleading with the federal government, which he dutifully loathes as a conservative, for assistance to cope with algal blooms connected to global warming, which he denies. Of course the disposition of Utah’s political leaders is similar, and so is the...

Additional waters closed as 'unprecedented' Utah Lake algal bloom moves north 20.7.2016 Salt Lake Tribune
Algal monitoring efforts continue to move northward as state environmental officials strive to get a handle on what the largest algal bloom in Utah Lake’s history means for Utah water quality. This is the first known instance where a bloom originating in Utah Lake has affected the Jordan River and other downstream systems. And concentrations within the bloom are exceptionally high, with some samples surpassing tens of millions of cyanobacteria — the so-called toxin-producing algae — per millilit... <iframe src="http://www.sltrib.com/csp/mediapool/sites/sltrib/pages/garss.csp" height="1" width="1" > </frame>

Farmers fear for crops as Utah Lake algae threat spreads to Salt Lake County 19.7.2016 Salt Lake Tribune
Stephanie Cannon’s tomatoes may go dry this week if algae from Utah Lake make their way into her irrigation canal. “I wouldn’t feel uncomfortable about watering my lawn with” irrigation water from the canal, said Cannon, a commercial tomato grower and president of the Upper Canal Irrigation Co. in Millcreek and Holladay, “but I don’t want to put it on our tomatoes.” State water officials announced Sunday that algae from Utah Lake, where a toxic algal bloom was discovered last week, appear to hav... <iframe src="http://www.sltrib.com/csp/mediapool/sites/sltrib/pages/garss.csp" height="1" width="1" > </frame>

DEQ warns against using water from Jordan River system and Utah Lake 18.7.2016 Salt Lake Tribune
Access to the Jordan River and lower Little Cottonwood Creek has been limited because aerial and ground surveys show elevated levels of a harmful algae in them, the Utah Department of Environmental Quality said Sunday. In addition, Utah Lake, which also contains a toxic algal bloom, remains closed, DEQ spokeswoman Donna Spangler said in a news release. The bloom covers 90 percent of the lake. There will be no estimate for at least a week on when the water in the lake, river and related canals ca... <iframe src="http://www.sltrib.com/csp/mediapool/sites/sltrib/pages/garss.csp" height="1" width="1" > </frame>

Algae covering 90 percent of Utah Lake is dissipating but becoming more toxic, possibly moving 17.7.2016 Salt Lake Tribune
The toxic algal bloom in Utah Lake is getting smaller but possibly more dangerous, officials say, as poisonous cyanobacteria cells release higher levels of toxins into the water as they die. Officials are also testing water in the Jordan River and canals fed by Utah Lake to determine whether the bloom is spreading, and farmers have been urged to avoid using irrigation water that comes from the lake.
