Did you have a problem with cucumber beetles? They carry a bacteria that causes Bacterial Wilt in some cucurbits. The link below has pictures.

There is a diagnostic test for bacterial wilt that can be done in the field. The presence of the E. tracheiphila causes the sap to become a milky color and acquire a sticky consistency. If the stem is cut near the crown and the ends are slowly pulled apart, the sap should form a viscous string(from Wikipedia).

I'm sorry D...sometimes the bugs get the best of us. Don't get discouraged.

Up until five or six years ago, I always had problems growing cukes. A suggestion on this forum resulted in my trying floating row covers and it has pretty much solved my problems (which, in all honesty, were never as bad as yours look). I would get a few cukes and then a variety of diseases, all cucumber beetle transmitted, apparently, would hit and then my garden resembled yours.
Now I cover the plants with a floating row cover on my 4 X 8 foot beds as soon as they are an inch or so tall and I have had a chance to thin appropriately. The cover stays on until the plants bloom. I previously lay down a soaker hose for watering but you can water through the row cover. The result right now is a bed of cukes that look they just jumped out of a seed catalog. Provide trellises or poles to grow your cukes vertically after the covers come off. I also select only the most disease resistant cuke varieties I can find. Have pretty much settled in on Alibi and especially Eureka. They are both pickling types but grow large enough for slicing and salad use. I have extended my use of row covers to Bush Beans, Radishes, and Lettuce with improved results here, also. It keeps both bugs and bunnies away. I know we are in quite different zones. I'm here on the shores of Buzzards Bay. But gardening anywhere has commonalities which might be shared to mutual benefit.
Good luck to you my friend. Hope this suggestion proves useful.

It's most likely not the aphids. Aphids are attracted to plants that are already under stress, so they are a secondary issue. It does seem to be some sort of wilt. Some varieties of cucumber are very susceptible to wilt. You may have better luck with another variety. Good luck!

Sconticut, with the floating row covers don't you need to hand pollinate?

Wolverine, he leaves the covers on until the plants bloom, then removes it...
