Hotham Sound[1] is a sidewater of Jervis Inlet on the South Coast of British Columbia, Canada, located near the mouth of that inlet on the north flank[2] of its lower reaches, roughly opposite the mouth of Sechelt Inlet. There is a deep basin at its entrance reaching a depth of 730 m (2,400 ft). Harmony Islands Marine Provincial Park is located on the east side of Hotham Sound.[3] The spectacular Harmony Falls, also called Freil Lake Falls, plunges a total of 444 m (1,457 ft) into the Sound.[4]
