Stayed in a walk-in tent site. Much better spacing than typical sites, though sites 2 & 3 were basically connected. The non-walk in sites in Loop B are typical to smaller than average and mostly suited for campers/RVs.
Pros : Site spacing/privacy was good Bathrooms and showers were clean. Firewood available at the park ($5 for 6 pieces self-serve). Location near the dam and lake trail is nice. Cell service was limited, but had reliable (but low) signal with T-Mobile at my site. Easy access (on foot) to all of the hiking trails.
Cons: The tent pads could use some leveling and there was some trash around the site. The major negative was generator noise coming from the facility just beyond the dam. Droning generator noise was on/off at all hours of the day and went on until 10pm in the evening. Not sure how far up in Loop B this was heard, but it was pretty loud in the walk-in site area.
