Nampa-Tsi Lodge 216 is the Order of the Arrow lodge serving Great Rivers Council in Columbia, Missouri. Part of Scouting America, the lodge brings members together around service, brotherhood, and adventure, supporting the council and its communities. Nampa-Tsi has seven chapters and holds two induction weekends each year, with opportunities for members and units to participate throughout the year.

The lodge organizes Ordeal inductions, fellowship events, leadership development training, conclave participation, and other gatherings. Members can pay dues, update their information, register for events, and access forms and resources through the lodge’s online services. Scoutmasters can also request a unit election to introduce eligible Scouts to the Order.

Nampa-Tsi explains the path from Ordeal to Brotherhood and Vigil Honor, and provides chapter information to help members find local connections. Its calendar highlights events such as Winterfest and Section G6 Foundations Training, while news, a podcast, and a gallery share lodge updates and experiences.
