There are four main drainage basins reaching to the slopes of Mount Spickard. Depot Creek flows west and northwest to join the Chilliwack River and, ultimately, the Fraser River, which flows into the Pacific Ocean in British Columbia. On the south side of Spickard are some headstreams of Perry Creek, which flows east to Little Beaver Creek and, via Ross Lake, the Skagit River. To the north Silver Lake Glacier sends meltwater into Silver Lake. Meltwater streams from glaciers on the east side of Mount Spickard join the outflow, Silver Creek, which flows east from Silver Lake to Ross Lake.
