The World of Waterfalls has been to this waterfall, which you can read about here.

For many years this underrated waterfall was listed as the third tallest in the book ‘The Top Ten of Everything’. But, then, after Cascata de Yumbilla was discovered and measured [whereby it became third tallest], Ramnefjellsfossen dropped to fourth. Whatever? I viewed this waterfall on a clear day in early June 2017. A sublime experience for me. Fortunately, the volume of water was insufficient for government authorities to target it for hydroelectric use. Not so, the case with the formerly magnificent Mongefossen, which was not flowing when I visited a few days later on.
