Wondering if someone out there can explain thr relationship between deeper water dencetites and weights for T-rigs and jigs.

density??

Don't know if it effects weights for fishing that much? never heard about that.

But....Water is most dense at 3. something degrees celsius if my memory holds true. That is just above freezing for my southern brothers.

So that is why water gets colder as you go down deeper (colder water is denser and will "sink") until you hit 3 degrees. 3 degree water will always be at the bottom if the lake has 3 degree water ie a northern lake in the winter. Most bass lakes (at least when you are out fishing from your boat) don't and the difference of density throughout the depths is probably minimal.

Did you know water is the only substance that is less dense when it takes on a solid form??? Strange stuff. Thats why ice on a lake is on the top! haha.

So I would just fish whatever weight sinker gets you the bottom contact/control you are looking for.

I hope that helps???

In short, there is no relationship.

The density of water increases by only about 0.02 g/mL from 75 deg C - 3 deg C. It is completely unimportant in choosing fishing weights.

If you wish to reach the bottom, the choice of weight is based on depth of the water, not density. You'll need a heavier weight to get to deeper depths. Too little weight and you'll spool out more line horizontally than vertically due to currents and it may even be difficult to reach bottom with a very light weight and deep lake.

Ice is less dense than water because the hydrogen bonding in ice is organized in a manner that forms an "open" octagon; this openness is empty space (air). Air is less dense than water (or ice) and its presence in the ice lowers the density. Ice has a density of approx. 0.92 g/mL (liquid water ~ 1.0 g/mL, varying slightly with temperature as mentioned previously). It's why ice floats in your ice tea.
