Saskatchewan's first Regional Park established in 1961.
In the mid 1950s the PFRA began work on the Lafleche Storage Project. This project was building a dam on the Wood River to control the flow of the river and conserve the runoff for local use for stock watering, irrigation and municipal purposes. Dr. Leonard Thomson, the PFRA director at that time, saw the reservoir as more than a source for these purposes; he also saw the possible recreation potential the reservoir would have. Dr. Thomson's idea was soon grasped by local residents and the seed for Thomson Lake Regional Park was sown. Thomson Lake Regional Park hold the very first regional park Charter dated March 21, 1961.
There are 20 amp power sites, 30 & 50 amp full hookup sites in addition to 235 seasonal sites and 16 designated non serviced sites. All sites are level and drained with gravel pads, picnic tables, fire pits and access to central trash cans and water taps. Washroom facilities are modern with flush toilets, coin operated showers and laundry facilities. A map to the campground sites and facilities is available at the park gate.
