The Splats'in First Nations people reside on Indian reserve lands adjacent to the City of Enderby to the south and across the Shuswap river to the east.

The Splats'in are the most southern tribe of the Shuswap Nation, the largest Interior Salish speaking First Nation in Canada whose aboriginal territory stretches from the BC/Alberta border near the Yellowhead Pass to the plateau west of the Fraser River, southeast to the Arrow Lakes and to the upper reaches of the Columbia River.

The Splats'in or 'Spallumcheen', the anglisized name they are commonly referred to as, are governed by an elected Chief and six Councilors.

The area of the reserve lands are as follows:

• Salmon River Reserve #1 3853 acres or 1559.31 hectares
• Enderby Reserve #2 5625 acres or 2276.44 hectares
• Sicamous Reserve #3 201 acres or 81.34 hectares
