I have always found waterfall/forest stream images to be a pain to color balance. I think it is because the scenes often contain different light temperatures. There may be some areas that are lit by sunlight, others in complete shade and all things in between.
Is the image a raw image? If so, what editing software are you using? If you are using Lightroom Classic/ACR, which color profile are you using? I have found that choosing the most pleasing color profile in the beginning makes color editing easier.....sometimes. I have had good results using the new Adaptive Color profile in Adobe Camera Raw or LrC.
If you use another raw editor maybe someone else can help.
