Permanent European settlement along Conjuring Creek and Wizard Lake began in earnest around 1904, when agricultural homesteaders arrived to clear the heavily forested, glacial terrain. In 1904, a local sawmill was established near the lake anticipating that a newly planned railway would pass through. However, when the railway plans fell through, the mill was forced to close down by 1905.

Resource extraction in the area went beyond timber. An underground coal mine operated on the southern shore of the lake near the creek's headwaters, supplying fuel to the local community until it finally shut down in the 1940s.

As the area grew, community institutions began to form. For instance, the Conjuring Creek School served families in the area during the early-to-mid 20th century (its historical wood-heater stove later found a preserved home in the nearby Glen Park Community Hall). The Post Office opened April 1, 1900, and closed on June 30, 1939. The first postmaster was John Sangster, who held the position until 1933.
