There are approximately 185 property owners on the four lakes, of whom 56 are year-round residents. The latest figure for paid-up members of the Hudson Lakes Association is 100, or 55% of the residents. The HLA estimates that there are approximately 600 people residing on the lakes during the summer months, with many more on long weekends, particularly the Regatta weekend. The 2006 Stats Can census figure for the total population of Hudson Township, including permanent lakes residents, is 309 (a figure being disputed by the Township). The Township estimates the population at 490.
The HLA is able to draw on a large number of volunteers for its events and activities. The water sampling is done by volunteers on each of the four lakes, and the swimming lessons drew enough volunteers to look after the 20-25 children who participated. The AGM typically has an attendance of 35-40 people.
