understanding Water Surface Tension

we often read or hear about the water’s surface tension and how it affects fly-leader-fly line floating/sinking abilities and also how aquatic insects can have a hard time breaking through it on their way to the surface and other insects can use it to literally walk on water. often described as some sticky, gluey thing that’s between water and air but what is it exactly ?

since i probably won’t be able to explain it without making any silly mistakes.., i’ll let this silly young lady do it for me !

“Africans do this with mosquitoes to help stop the spread of Malaria, material (soap) is put in the water to break the surface tension. Mosquitoes use water tension to land on the water so that they can lay their eggs. Without the water tension, they sink like that spring.”

so, how does this help us in our fly fishing world ?
apart from something cool to know and yet another example of how amazing water is, if you’re a fisher that doesn’t think that a floating tippet near a dry fly makes a difference and you still catch fish, then this won’t help.
however, if you want to up your game, specially on fish that aren’t on a feeding rampage or on slower waters or on any types of waters and you’re dealing with fish that might be in a mild-alert stage then one of the best ways to have a chance with them is to degrease a good 2-3 ft of your terminal end leader or tippet with sink paste to get it to break the surface tension as soon as the fly alights on the water.

as a reminder, sink pastes are typically made of three ingredients- liquid soap, glycerine and clay powder. the powder acts as a binding agent (it’s also a very mild abrasive that removes a little surface shine from monofilaments), the glycerine keeps the paste from drying out and the main ingredient is as seen in the accompanying videos: soap, which allows the tippet to sink under the surface rapidly and not be so visible and light reflecting and/or create nasty shadows on the riverbed on a sunny day.
if currents aren’t too strong sink paste also greatly helps unweighted wet flies and nymphs to get into the feeding zone without having to weigh down the flies themselves or use split shot or whatever resulting in a free moving, more realistic impression of life to the fly. this last point is no secret but it’s rarely brought up and it’s a real gem to have in your bag of tricks.

since science and trippy often go hand-in-hand, here’s another eye candy example of surface tension experiments,

and how even water itself can be subject to the sticky-gluey barrier.

Letting the days go by, let the water hold me down.

” Water dissolving and water removing
There is water at the bottom of the ocean
Remove the water, carry the water
Remove the water from the bottom of the ocean
Letting the days go by, let the water hold me down

Letting the days go by, water flowing underground
Into the blue again, after the money’s gone
Once in a lifetime, water flowing underground
Into the blue again, into silent water
Under the rocks and stones, there is water underground
Letting the days go by, into silent water. “

“That’s not very exciting”.

” you might be right.”

“Was it supposed to be exciting ?”
“not really.”

” It is kinda dreamy though…”
“i like dreaming.”

” Yeah, dreaming is exciting.”
“so, does that make it exciting after all ?”

“Yeah, a little. Let’s go have some chocolate.”

Words on Water

although recently dwarfed by a ‘Kerouacish’ mainstream approach from the west, fly fishing literature in the UK is still thriving and strong and this pleasant, entertaining little 30 minute listen will put the interested reader in touch with several authors of interest.

it’s about the water, what it contains and incorporating these in our lives more that just catching fish.

How To Properly Throw Trout From An Aeroplane

by Anders Halverson

“First, Reese tried freezing the fish in ice blocks and parachuting them in ice cream containers. Both of these techniques, though, proved dangerous and difficult. And so, one day, Reese and his assistants tried a simpler technique. They put 50 trout and some water into a five-gallon (19-litre) can and threw it out the window toward a hatchery pond about 350 feet (107m) below. They missed, and the can bounced along the rocks nearby instead. But when observers recovered the twisted metal debris, they found 16 fish still swimming in the small amount of water that remained. It was a stunning result for fishery managers who had long been telling anglers not to throw fish back, but to gently place them back in the water.”
