I just saw that the DNG was available so I did a few things.
Here are 2 screen shots showing what can be done with the curves adjustments:

And my choice (including crop)

Coming into this really late, but up front let me clarify something - yes, you want to make sure you maximize the color space by setting your black and white limits, but 1) this needs to be appropriate to your image (it's a guideline, not a commandment) and 2) I do it using a Levels adjustment in Photoshop and not usually in ACR. This is to maximize the dynamic range of the photograph. But fog shots are the antithesis of dynamic range and are almost exclusively a squashed subset, so you've effectively undone the subtleties.
Rule #1 is serve the photograph.

Here is what I did to your image:
Downloaded into PS CC 2015, automagically opened in ACR.
Here are my ACR 9.3 settings:
temp - 6200
tint - +2
Exposure - +0.45
Contrast - +39
Highlights - -29
Shadows - -55
Whites - -14
Blacks - -24
Clarity - +48
Vibrance - +27
Saturation - +33
Used Lens Profile Corrections
De-Haze - -5
Default Camera Calibration
Used Spot Healing Brush Tool to remove Power Lines, bird feeder, ducks, and white spots in water.
Used Lasso tool with majorly jagged edges to select tree foliage in center of image, and increased saturation in this area very slightly, so you could not see the transition.
Used Lasso tool with reflection of same, using same method.
Reduced image size to 1200 width, and then used unsharp mask just a little.
I paid no atttention to histogram.
I did pay attention to Binky, my cat, as he navigated the keyboard as I worked. Hairs between the keys could have changed the values of PP somewhat.
I don't take many fog shots, as much as I like them. It is a challenge as the adjustments that sharpen and give our work pop, eliminates the foggy "look" to a certain degree.
Thank the gods I read that twice, I thought it was asking for advice to edit frog photos.
I'd hop right on that!
One thing I forgot to mention is that when shooting fog it is sometimes better to give exposure a bit of + so the whites are really white. Otherwise the shot sometimes looks like soup.
