"Swimming" Pond Is Now Open

9/11/2016

3 Comments

 
The water expert at Ramsey County has determined that the pond is free of Blue Green Algae, and it was unlocked just today.

The water is clear, and the surface matter is simple duckweed, which is harmless and actually good for the water quality. 

However, remember this is a watershed pond (as is the case with all the ponds in BC), which means it is fed by surface run-off from the surrounding areas (streets, lawns, etc.). My dogs have been swimming in and drinking it for 10 years, and have never had a problem. Other dogs partake once and occasionally come away with ear, eye, skin or intestinal problems -- although there have never been reports of a serious illness. 

​
The cleanliness of these ponds is very dependent on keeping the park free of feces residue................ so scoop your poop, and pick up any orphans you encounter.

Pond Re-opening?

8/31/2016

1 Comment

 
It appears the pond is ready to be reopened, but we have asked P&R to test it one more time before the gates are unlocked, just to be certain. 
The scum on top of the pond is harmless duckweed (the brownish-reddish patches is just decaying duckweed); The water is clear, with none of the telltale greenish color that denotes the presence of the blue green algae.

Swimming Pond Closure

7/16/2016

P&R tested the water in the "swimming pond" recently, and I am pleased to say it is much better than when it was first tested (around June 1). 

Even though the pond still tests positive for BGA, the expert who did the testing feels it would be safe to reopen it for dog swimming. However, P&R feels it would be prudent (their phrase was "abundance of caution") to keep the pond closed at least through the summer, since it is possible spells of hot weather may bring elevated levels of BGA.

Water Quality Update from Jennifer Fink

6/30/2014

 
I have spoken to our water quality specialist at the County. The photos that were provided - which were very helpful! Are a common duckweed. That level of surface vegetation makes it HIGHLY unlikely that any algae exists in the ponds.

That being said - two pups were extremely sick after swimming in them, which is likely due to some sort of micro-organism in the water, which we are unable to test for. Some dogs may get sick from it, others may not.

Those ponds are not very deep, and are not monitored for water quality. Which makes them subject to water quality issues. So please use them at your own risk. If you have any further questions, please let me know.

Water Quality - June 29th, 2014

Blue Green Algae warnings come around every summer, but it appears the problem with blue-green algae is much more pronounced this year. BC regulars will recognize the common duckweed, which is not a problem. What you should look for a bright green scum on the water (almost like paint).  Here is some more info from the MN Pollution Control Agency: 

Summertime in Minnesota: When in doubt, best keep out!
When temperatures climb and the summer sun beats down, conditions are ripe for Minnesota lakes to produce harmful algae blooms, some of which can be harmful to pets and humans.

What: Harmful algal blooms (HAB) are blue-green (cyanobacterial) algal blooms containing toxins or other noxious chemicals, which can pose harmful health risks.

Why is this a concern? People or animals may develop skin irritation or upper respiratory problems from exposure to HAB, and in extreme cases, dogs and other animals have even died after drinking lake water containing these toxins.

Where: Severe blue-green algal blooms typically occur on lakes with poor water quality (high in nutrients), and look like green paint, pea soup, or a thick green cake (see photo gallery below for examples). HAB often result in extremely low water clarity (less than 1 foot). There is no visual way to predict the toxicity of an algal bloom

What should I do if I suspect a HAB on my lake? When these conditions are present, people should avoid contact with the water and they should prevent animals from swimming in or drinking the water. Scientists do not yet know what causes some blooms to produce toxins while others do not, so the safest course of action is to avoid contact with all blue-green blooms.

What does it look like? Blue-green algae can be hard to distinguish from other types of algae. While it's often described as looking like pea soup or spilled green paint, it can take other forms as well.  The photos on their website show some of the diversity of blue-green's appearances and also provides some examples of other types of algae or plants that may be mistaken for blue-green algae.

Algae Blooms on Ponds

7/11/2012

With all the hot weather, we should be cautious about the ponds. Bloomington posted the notice below, which may be applicable to the ponds at BC. Bottom Line: OK for dogs to swim, but you should rinse them off when you get home. The also advise against letting your dog drink the pond water (I have no idea how you would do that).
