Why I don't swim in lakes.

I moved from Western New York to Texas 20 years ago.
Spend a lot of time paddling kayaks in Central Texas lakes, rivers and in the Gulf of Mexico.
Spend a lot of time kiteboarding in Texas lakes and in the Gulf.
Spent a lot of time swimming in all of these bodies of water.
Never had any trouble in any of these.
We have five different kinds of rattlesnakes, as well as water moccasins, copperheads, and coral snakes.
More people are killed by lightning strikes every year here than from poisonous snake bites.
I also know the chances of getting attacked by a shark are very slim but I still get a bit nervous when I fall off my board in the Gulf when I am a bit away from shore.
Many species of sharks do come close to shore all over the world, including some very big sharks.
Not enjoying nature for fear of animals is a shame, people are far more dangerous than animals anyway!
 
I never had a problem in any lake in the midwestern US. The lakes in SE WI are all very clean. I've done some ocean swimming, as well. It's fine as long as you know the places to avoid.
I grew up near Lake Geneva, WI, and that lake is exceptionally clean and safe as long as you're not a dum-dum. There is the occasional drunken accident, but usually very few.
The weirdest lake I swam in was Lake Powell in AZ and UT. I didn't particularly enjoy it. It's too creepy knowing there's all that sunken canyon down there.
There are people who swim in the Mississippi River. I'm not that brave/crazy.
 
Guys just a pet peeve here but there is no such thing as a poisonous snake...they are in fact venomous!

and while I realize poisonous is a synonym it has to do with the delivery system...

poisonous = substance or plant causing or capable of causing death or illness if taken into the body.

venomous = of animals, especially snakes, or their parts secreting venom; capable of injecting venom by means of a bite or sting.

I grew up in East Texas where encounters with this snake were practically an everyday occurrence. It was this combined with the irrational fear of my Ex-Navy Seal father towards these fascinating animals that led me to become a Herpetologist...(google it)

here is some knowledge for you...

the common cottonmouth or water moccasin

Order: Squamata
Family: Viperidae
Genus/species: Agkistrodon piscivorus

Cottonmouths are normally not very aggressive creatures. that's right I typed it...They are usually not aggressive and will not attack unless agitated. One of their unique behaviors is their ability to "stand their ground." When thoroughly aroused, a cottonmouth coils its body and threatens the intruder with its mouth wide open and its fangs exposed, showing the white lining of its mouth (thus its common name, the cottonmouth). they seem aggressive to people who do not understand their behavior...as with most pit vipers their venom is quite precious total venom replacement actually requires up to three weeks, after being fully depleted. As a result they play a game where they appear to be aggressive hoping you are the one that will back down.

The aggressiveness of these snakes has been greatly exaggerated. In tests designed to measure the various behavioral responses by wild specimens to encounters with people, 23 of 45 (51%) tried to escape, while 28 of 36 (78%) resorted to threat displays and other defensive tactics. Only when they were picked up with a mechanical hand were they likely to actually bite. When sufficiently stressed or threatened, this species engages in a characteristic threat display that includes vibrating its tail and throwing its head back with its mouth open to display the startling white interior, often making a loud hiss while the neck and front part of the body are pulled into an S-shaped position. Many of its common names, including "cottonmouth" and "gaper", refer to this behavior, while its habit of snapping its jaws shut when anything touches its mouth has earned it the name "trap-jaw" in some areas. Other defensive responses can include flattening the body and emitting a strong, pungent secretion from the anal glands located at the base of the tail. This musk may be ejected in thin jets if the snake is sufficiently agitated or restrained.

The cottonmouth is a pit viper. It possesses a pair of heat-sensing pits between their eyes and nostrils. The pit consists of two cavities, an outer and an inner, which are separated by a membrane. They are able to detect temperature differences of as little as 1.8° F (1° C). higher or lower than that of the background. They allow the snakes to strike very accurately at the source of heat.

Cottonmouths are primarily active at night, but they bask in the sun during the day. Because they spend much of their time in water, and water draws away heat more quickly than air, they must somehow maintain a high body temperature, particularly for their digestive metabolism. This is accomplished by basking.

Cottonmouth venom is more toxic than that of (the copperhead) and is rich with tissue-destructive enzymes. It is a powerful cytotoxic venom that destroys tissue. Although deaths are rare, the bite could leave scars and, on occasion, require amputation. Absent an anaphylactic reaction in a bitten individual, however, the venom does not cause systemic reactions in victims and does not contain neurotoxic components that are present in numerous rattlesnake species.

the Copperhead Agkistrodon contortrix is a cousin to the cottonmouth...

Although venomous, these snakes are generally not aggressive and bites are rarely fatal. Copperhead venom has an estimated lethal dose of around 100 mg, and tests on mice show its potency is among the lowest of all pit vipers, and slightly weaker than that of its close relative, the cottonmouth. Copperheads often employ a "warning bite" when stepped on or agitated and inject a relatively small amount of venom, if any at all. "Dry bites" involving no venom are particularly common with the copperhead, though all pit vipers are capable of a dry bite.

The venom of the southern copperhead has been found to hold a protein called "contortrostatin" that halts the growth of cancer cells in mice and also stops the migration of the tumors to other sites. Human testing is currently in the works...

In Canada the only thing to fear in a lake is the dreaded shrink-dink.
Yeah, it was a bit of a shock moving from Western New York (which is Canada basically) to Central Texas.
We've got gators in Texas and I did not know that before I moved here, we don't see them much in this part of Texas but once in a while a Texas Parks and Wildlife employee will have to move one out of some body of water.
When we bought our house here, we spent a month finding scorpions running across floors about every other day, thought their sting could kill us, reality is more like a wasp sting.
We get big honking tarantulas on the outside of the house occasionally, the wolf spiders are big and creepy, we've got black widows and brown recluse as well.
Rattlesnakes occasionally turn up in the yard or in the garage and some of them have been pretty large.
One morning I opened my back door in the kitchen and a small two foot long rattlesnake fell into my kitchen! ..that will wake you up.
Coyotes pass along my back fence almost every day for all the years I've lived here, we see them all the time, I live in a suburban neighborhood but the coyotes keep doing what they've always done, if you leave domestic cats outside at night they will be taken, sometimes they will grab a small dog as well.
Lots of hawks and falcons, we even have eagles out by one of the lakes near here, lots of big azz turkey buzzards cleaning up any road kill.
We have bobcats here for sure but I've never seen one, we also have mountain lions in this area now, that's a new thing apparently.
Most native plants in Texas will bite you as well, there are thorns or points that will stick you on tons of plants here, but there are wildflowers everywhere as well.
I like all the plant and animal wildlife here, it is much more interesting than New York.
All that potentially dangerous stuff here and the only thing that has bitten/stung me is a scorpion....and a few jellyfish in Corpus Christi. :D
.....and those damn fire ants, I hate them.

You can't tell from looking at fresh water whether it has Giardia in it or not...

I had to look that up. It seems that alomost all infections are from human to human contact and being infected by drinking contaminated lakewater is exceptionally rare.

I'm 100X more likely to be sucked up by a tornado passing over the lake than to be infected with Giardia while swimming.
 
ed me to become a Herpetologist...

You know that cute little rhyme they came up with to help identify milk snakes from coral snakes? I've developed my own version:

Yellow, red, and black? Step the **** back!

If an animal has adopted danger colors, that's good enough for me. I'm not going to try and pet a snake and get all cuddly with it just because it's not venomous! :laugh:
 
I think most snakes are not a problem unless you literally stumble on them, one evening I was cleaning up my garage and went to grab something on the floor in the corner and realized I had my hand six inches from a baby rattlesnake that was coiled up and just sitting there!
Stopped one second before I grabbed him with my hand, no more cleaning the garage without turning the lights on!
Luckily it was very cool and the little dude was not moving much so he did not bite me.

Giardia is a parasite from animal feces in water. I got it from drinking lakewater.
You can get it from mountain streams that look pristine. Anybody of fresh water actually, where animals have been known to frequent.
It's not uncommon where I live....

I've had Giardia but I haven't been sucked up by a tornado yet.....
 
^^^^ H2O plus alcohol equals ^^^^

Edit: For some reason, even responsible people who would never get in a car intoxicated think it is ok to do so on the water. Over my many years of boating, I have seen this many times. Ok, rant over.
Says the guy who let's his dog steer the boat ;)

Edit: now I read I'm not the first to note that irony

Sharks all over the world come close to shore (including some very big ones), there are a few species that don't but many, many do.
Yep...we have Great Whites that come right in to the surf line here. But it is rare that anyone gets chowed. I can only think of three fatalities in the last few years. Ironically, two of them were at Shark Beach near Vandenburg AFB in Central California. The other was in San Diego.
