While browsing the local on-line news, I came across this 'explanation' provided by a neighborhood spokesman to a homeowner, which was then turned over to a reporter. The HO believed a toxic algae-killer substance was the cause of a fish kill. I paste it here as I found it {all crammed together}.

The treatment chemical isn’t the problem, according to the biologist. Rather, the algae decomposing burns up the oxygen in the water making the water to low on oxygen to support the fish. The chemical isn’t directly killing them. The same thing happens in nature all the time when algae blooms out of control and consumes all the oxygen in the water. The fountain in the pond helps to deoxygenate the water when algae decomposes, unfortunately this time it appears that it was not fast enough. Algae is a worldwide problem that is aggravated by the overuse of fertilizers that is present in runoff. Unfortunately, with Spring here and everyone working on their lawns, things like this can happen. Frankly xxxxxxxx to never experience kills like this again mankind has to stop using fertilizers in excess. Xxxxxxx summed it up succinctly in his comment. We are the cause of the algae, which would have killed the fish if left untreated. The fountain was supposed to reoxygenate the water as it ran, but unfortunately the algae decomposes at a higher rate than oxygen could return. The company did not even use a half dose from the recommended dosing. We see this issue in our oceans as well. So if you want to never see this again, convince residents to stop fertilizing. Remember that a lot of the water in the pond is runoff.

I see a number of problems, on several levels. The spokesman actually typed his reply. He wasn't quoted speaking verbally, off-the-cuff. The reporter didn't bother cleaning up the errors before publication.

This mis-information is so rampant these days, then picked up by the press and 'reported'. It's obvious the spokesman has picked up 'bits-n-pieces' and attempted to offer an explanation but he's got his facts mixed up and others just wrong. Then attempts to connect-the-dots to reach a conclusion that doesn't make sense.

GIGO...
 
Apart from "The fountain in the pond helps to deoxygenate the water when algae decomposes" I don't see any disinformation. Should be "oxygenate" but its corrected later on, so probably just a typo.

One could criticise the style, but you don't have to look very hard to find much worse examples of disinformation.

Check out the current "Brake fluid question" thread, right here in our own virtual neighborhood, for instance.
 
Had a similar issue with a semi-private lake. Trout were floating like old pop bottles. My friend's family contacted the local news, it became the 5 o'clock story. The cause turned out to be a natural algae problem, nobody specific really to blame...

Didn't stop the news from turning it into a big time TV story, but there was really nothing at the bottom of it. It's a semi natural occurrence. (with the help of fertilizer runoff)
 
Not sure if it is algae or something else, but the salt water bays on eastern Long Island (NY) have been loaded with brown tide in recent years. Many attribute it to runoff from the many new homes built on previously undeveloped wetlands and near-wetlands.

The water looks like coffee with a touch of milk. Water visibility is probably less than 3 feet in many areas. The shellfish industry is pretty much dead in those areas. Fish still are present, as they have to eat. Quite a bit different than it was several decades earlier. That is progress for you.
 
Can't just blame fertiliser for the algae...it's nutrients of all descriptions, regional overloaded sewage plants, septics, leaves and grass washed down drains...and don't forget fertiliser runoff.

Then expect to have a pristine fish filled waterhole rather that nutrient laden algae pond slime at the foot of the lawn.

Then expect algicide to make the problem disappear.

Then get all precious about whether or not the algicide was the root cause of the fish kill...diluting the blame upstream to the lawnowners (and ultimately thier HOA ???)
 
Decided to google "The treatment chemical isn’t the problem, according to the biologist. Rather, the algae decomposing burns up the oxygen in the water making the water to low on oxygen to support the fish. "

According to the neighbors, a company -- which was hired by the Homeowners Association to get rid of algae in the pond -- dropped the oxygen levels in the water while they were getting rid of the algae, which caused the fish to die.

The company has since then removed the fish Saturday afternoon and the HOA tells KVUE they're restocking the fish at no cost.

Below is a conversation exchange between a concerned neighbor and the President of the HOA, which was given to KVUE:

HOA President: The company that was handling the algae kill took full responsibility with no prompting from the HOA. They’re extremely apologetic in a restocking the fish at no cost to us. Frankly, it’s the model of how you’re supposed to do customer service.

Neighbor: The problem is bigger than just a customer service issue. The water is contaminated with something that is killing hundreds of fish. Yes, the fish are gone and it smell is better and it sounds like new fish are coming our way (poor fish). I’d like to know who manufactured the treatment and how many other areas have been treated with that particular solution. What product was used and where did it come from? What are the other potential side effects from this treatment?

This is a very common scenario, blown out of proportion in this case by alarmist ninnys with little clue what they are talking about, fearing global ecologic disasters. Nature has very effective self-balancing methods biologists and chemists easily explain, but typical man-on-the-street people are simply unaware of. So media types leverage the sensational to get eyeballs on their marketing.

The pond simply was not properly maintained. Private pond owners are well aware of the risks posed by algae blooms and employ things like barley straw bales which naturally decompose in the sun, producing a safe algacide that harms nothing. The company rightfully accepted responsibility because they did not correctly calculate the oxygen exchange rate for the size of the pond, available aeration and amount of chemical used. Pretty simple - to people who understand what what is going on there. Then there's the twit lamenting "poor fish." The only question in this regard is whether or not they are stupid enough to make the same mistake over and over again, or properly maintain the pond to start with.
 
Yep, that's it. If you watch the video, you'll notice a few things missing. One is the fountain head. Where is it? The anchor says "hundreds" "thousands"...I don't think so. Also not sure if this pond/ditch has water in it throughout the year. It looks to me more like a storm runoff ditch than a neighborhood "pond".
