(KRON) — More than 1,000 pounds of fish passed away at Lake Elizabeth in Fremont today, a city authorities informed KRON4. Officials stated fish in the lake were taking a breath one-fifth of their regular oxygen degrees.
Fremont Director of Communications and Legislative Affairs Geneva Bosques stated the fatalities are because of the warmth. There are generally fish fatalities as the climate heats up, yet today’s fatalities were greater than normal, she stated.
“The fact that we are not getting the afternoon and evening cooldowns we historically experience here in Fremont is exacerbating the problem and not allowing the water temperature to drop and partially improve overnight,” a tweet from the City of Fremont stated.
Bosques stated the warmth brought the oxygen degrees from its regular degree of 5.0 to listed below 1.0. Fish generally die when degrees go down listed below 2.0.
City personnel looked out to the scenario on Wednesday. Staffers started tidying up the dead fish that day and have actually proceeded making rounds throughout the week.
Bosques stated the lake is simply 4 feet deep at its inmost locations. More water was included in the lake to preserve the water degree and reduce water temperature level.

On Thursday, an outdoors expert examined the scenario. The city is evaluating to see if various other variables like algae and germs go to play.
“The City will continue working with our consultant and partners to come up with long-term options and solutions that can help us manage these extreme weather and climate change impacts including the use of pumps and other devices to assist with improved water circulation and monitoring. There are also long-term capital projects being discussed that could increase the depth and flood capacity of the lake,” the city published.
The city includes 300-1,000 pounds of catfish and trout to the lake every April for a angling occasion.
