ONION FALLS is not a destination waterfall. Why you ask? Because it is primarily a spillway for the Lake Glenville Dam in North Carolina and its orientation and property restrictions make it difficult to view. In fact, it is waterfalls like this that have given rise to my desire for a drone.
Apparently this is not the original Onion Falls. When the river was impounded in the 1940's, the first waterfall was covered over by the dam according to some sources. Still, mapmakers used the same name for the new waterfall location. The name is inspired by the look of the water as it cascades over the round rock surface and gives the appearance of the skin of a white onion.
Based on topography maps, the crest of Onion Falls lies just beyond the dam floodgates at around 3,485 feet and falls like a giant waterslide to its base around 3,245 feet, making the total overall height around 240 feet.

PRO TIP - There is a small parking area near the dam power house, but signs restrict anyone from following the service road down to the base of the falls. The signs warn of police arrest if caught trespassing, so I took heed despite my overwhelming temptation to risk it! THEE BEST VIEW will be just beyond the dam where a small pull-off across from the lake leads to a trail that allows for a distant view of the falls. You will see a metered power box and two metal poles to mark the beginning of the short trail.
It also appears possible to bushwhack to the falls by following the river upstream from the High Falls trail, but not sure that is advisable considering the trespass warnings.

[ FINAL THOUGHTS ]
While the falls flow is heavily restricted by the dam, the gates have scheduled releases at least 4 times a year making this waterfall a BEAST!!! I highly recommend looking up the "bypass" release dates and planning a trip accordingly for the best and most spectacular look of the falls. On those dates, use Onion Falls as a bonus waterfall as you hike to nearby High Falls downstream. Both High Falls and Onion Falls go from attractive to flat out stunning during the dam release. I HIGHLY RECOMMEND visiting on those dates!
Also be sure to check out the The Pines Recreation Area to make it a full day of hiking, waterfall chasing and beach fun and on the opposite side of the lake is Hurricane Falls for a little more waterfall exploration!
