Clutha sit comfortably on top of the table after a near-perfect first round.
Clutha were unbeaten in round one and have 34 points out of an available 35.
They locked away the South Otago Banner and Springbok Horns last weekend in their win over Toko at Milton.
Clutha head to Swamp Hen Park this weekend to take on an Owaka side who managed to secure their first win of the season last weekend against Lawrence.
The Art Bloxham Cup is on the line with Clutha going into the match as heavy favourites.
The Heriot Rugby Club celebrates its 140th jubilee this weekend with an action-packed weekend of rugby planned.
The Heriot premier side have hit a purple patch of form and now have two wins on the bounce and sit just outside the top four.
Their last-gasp win over Crescent last weekend showed a resilience that perhaps has been lacking in recent seasons.
Heriot take on Lawrence in the main event tomorrow, with the West Otago Shield up for grabs. Lawrence are the only side not to record a win in round one of competition.
Crescent are in the middle of a form slump with two losses in a row.
The Kaitangata-based side lost a close match in Heriot last weekend which saw them lose track of the teams in front of them.
One of those sides, West Taieri, travel to Kaitangata tomorrow in what promises to be a massive clash of two potential semifinalists.
West Taieri are coming off a successful jubilee last weekend but know their hard work has only started.
Toko host Clutha Valley in the last match of the weekend with Toko favourites to keep their spot in the top four after only their second loss of the season last weekend against Clutha.
