Ph and chlorine effectiveness

Due to lower temps I'm running my waterfall quite a bit more. I haven't bothered checking PH since I'm not swimming but will a higher ph decrease or otherwise inhibit chlorine?

With nearly any amount of CYA in the water the strength of chlorine is not adversely impacted by higher pH levels until the pH rises to a point that it would also create issues elsewhere in the pool.
