It crushed Roxburgh 87-5 at home to retain the McIntosh Cup for the summer.
Clutha's forward pack was solid and made inroads up front, allowing its backs to attack with purpose.
This performance was needed from the home side after a couple of lacklustre showings of late.
Clutha's 13 tries were scored by 12 different players. Utility back Zak Thoms scored 32 points, possibly a club record. He started at fullback and injected himself into the backline well to set up multiple tries and score a double.
Clutha lost nothing when Thoms moved to halfback later.
Prop Phil Keighley had a strong game, and Maddison Latta played well on debut.
Crescent secured a home semifinal with a 41-19 win over Heriot at Kaitangata.
The forwards got through a mountain of work and the backs found plenty of holes in the Heriot defence.
Heriot coach Craig Stanway was disappointed with his team's effort.
It had some key players missing, but Stanway said that was no excuse.
It was hard to pick any individuals from the Crescent team's performance but prop Lester Papali'i and midfield combination Gene McHardy and Chase Owen were very good.
Owaka leapfrogged Heriot into third place with a composed 33-7 win over Clinton at Owaka.
The home side had the majority of territory and possession in the first half and went into the break 21-0 ahead.
Clinton wrestled back some momentum in the early stages of the second half, but Owaka finished the stronger.
Clutha Valley gave stalwart Hamish Wilson something to celebrate in his 200th game for the club with a 27-17 win over Toko at Clydevale.
The first half was an even encounter and the score was 12-12 at the break, but Clutha Valley pulled away.
