Sorry Justin_time. My take on your question is simple. The shallow water will be the only areas of the lake where daytime oxygen levels and natural food production will be anywhere near normal levels. This at a time when the amount of bait going in is at a minimum means increasingly active and therefore hungry carp will have to feed there. Until the number of anglers increases after the general winter layoff and start pouring bait in there will be very little food in the rest of the lake. Also carp do naturally seek out the shallows in late winter, early spring as they are the first areas to warm up with increasing sunlight.

You do realise the dyes are non-toxic. Bit of a stretch to compare to DDT and lead.
There will be an effect on the natural environment but as long as it's done properly the effect wont be as drastic as a couple of you are making it out to be. You also have to weigh up the other effects, an oxygen crash could kill everything in the lake, the dye can help prevent that. The biggest and most natural pits can succumb to o2 crashes.
And when you think about it, why is it so weedy? Is it natural or is it a result of phosphates leaching in off surrounding farmland? Fertilisers, etc. what if it's artificially weedy due to man made influence and the dye is rebalancing the environment?
No point forming an opinion on something without thinking about the wider picture is there.

Plus in most instances the Dye is being used to treat an invasive species of weed, that's chocking the life out of the Lake

Why do people act like this online. Trying to sound like they are an expert on the topic they are asking questions about.

In fairness he's not getting an answer to his question. The rights/wrongs and ifs/buts were already covered by his thread back in August:

He's now asking what it'll do to the fish's behavior in early spring so he can take advantage of it.

2 lakes near me use the blue dye to help with the extreme weed problems they have, 1 lake it doesn't seem to effect the fishing at all but the other once it goes in nothing comes out for at 2/3 weeks it's been like the last few years since they started using it so definitely effects it in some way but then after those 2/3 weeks it goes back to normal
I'm not against using it though I can see why they use it because on another one they drain the lake and pull the weed out by hand with rakes so takes up a lot more time

He doesn't sound like he wants to listen though. Even in that post he doesn't pay the blindest but of interest in anyone who doesn't think that dye is just there to kill everything in sight.
If you thought that putting dye in a lake was ecological holocaust, why would you carry on fishing that lake

I don't disagree.
Edit: I see a lot of talk about the use of dye for inhibiting weed growth. I can't say I agree with its use for that purpose. For me the dye is invaluable for use on waters that suffer with bad algae issues. It needs to work for the ecosystem, not against it.

To reply to the OP, on the original topic.
It sounds like they have been dying it for multiple years previously. All I can say is that the entire ecology in the lake will be used to it and will have adapted.
Quite simply, although the dye should theoretically make the water cooler (blocking sunlight and UV to the depths will mean they wont warm up), on a large pit that will likely have water turnover due to wind constantly, it probably wont make much of an impact at all. Plenty of deep lakes in the country, they all are a month or so behind the "normal" cycle. So it may start slower but it will still fish later in the year than other places, that is IF the dye has any real effect on the temps.

No expert, but I don't think water is heated by UV, it will be heated mainly by Infrared(IR)
Blue dye is used since it absorbs other colours of the visible spectrum and reflects blue, hence you see blue. The chlorophyll, the pigment in weed that makes it look green absorbs light at the red/yellow end of the spectrum. Since the blue dye is absorbing these wavelengths there is less light of the particular wavelength used by the weed, hence its growth can be controlled.
If you want to absorb UV, then the lake would need to be yellow, not blue
