The Twin Rivers Senior Hockey League is a men's Senior A hockey league based in north-central Saskatchewan north of Saskatoon. The league was established for the 2016-17 season. The league was announced as being an attempt to bring back real grass roots hockey, made up of local players who have a real genuine love for the game. The call was put out by the Warman Wildcats for any and all players interested in playing senior hockey to come out for try outs.
The league was announced in mid-September 2016. The Warman Wildcats joined from the Fort Carlton Senior Hockey League. The Rosthern Wheat Kings joined from the Wheatland Senior Hockey League and the Birch Hills Blackhawks joined from the Beaver Lakes Hockey League. The league was also announced with teams from Clavet (Cougars), Cudworth, St. Louis, and Vonda, Saskatchewan. A second team from Dalmeny (Dalmeny Sabers) will be a member of the league (not the present team (Dalmeny Fury) from the Fort Carlton Senior Hockey League.
On January 5, 2017 it was announced that the Vonda Chiefs had decided to discontinue playing in the league. The team's games were considered forfeits including the one's already played (and those stats deleted). The league decided to use a 18/16 multiplier/divider to determine the league scoring champion as the North Division teams would now have two fewer games played than the South Division.
