Here's my take! Nice image, detailed as you can see the people along the left side road leading to the ledge above the water in the middle-ground area when magnified. Usually when taking waterfall shots, photogs like the "cottony" almost detailless effect when using a slow shutter speed to not freeze the water's movement. Overall, your image, to me appears a little flat. I feel the image needed a little brightening and a little contrast. Using Nik Software's "Control Point" tool in Nikon's older Capture NX2 program, I lightened the left side and also the central highlight area of the flowing water to draw the eye to that area.

Just my 2 cents! Be well all! Ed

First, it would have been helpful to have posted the unedited jpeg. The exif indicates that this image has already been edited with PSE and LR.

Rather than flattening the whole lake, the idea was to still have contrast between the smooth water and the falls. However, bringing more details into the falls reduces the overall whiteness. Part of the problem is that there is detail in the water but if viewed in a small format, it appears white, just due to compression. With that said, here’s what I recommed:

1) denoising the image.

2) in LR (or ACR) make the following adjustments
Exposure: -0.5
Highlights: -100
White: -25
Texture: +50
Dehaze: +10

3) Mask the changes only to the water

4) Straighten the horizon using the distant lake edge.

Hope this helps

According to Lightroom the whites are more than 2.5 stops from being blown. Lowering the whites and highlights with the basic (i.e. global) adjustments will get you so far but you'll need to replace the lost contrast if you do that. The most effective measure is to select the brightest parts of the waterfall and give them their own adjustments. I tried a combination of lowered highlights and lowered brightness plus extra contrast, sharpening and a touch of extra clarity for that selection. If you use the brush's auto mask (or "Find Edges" or whatever your editor calls it) to apply those adjustments, together with using the brush in Erase mode with auto mask to clean up the selection, you should be able to keep the adjustments to just the highlights of the waterfall. I'll post my results if you like.
