It was named after Dr Leonard Thomson who was the director of the Prairie Farm Rehabilitation Administration (PFRA) at the time.
Most of Thomson Lake is within the Rural Municipality of Wood River No. 74 while the northern tip is within the Rural Municipality of Gravelbourg No. 104. Thomson Lake Regional Park is located on the eastern shore of the lake and, other than the cabins at the park, there is one small cottage community on the lake called Gaumond Bay; it is located along a bay at the northern end of the lake.

It received its charter on 21 March 1961 and officially opened on 10 July of that same year. Seeing the potential for a great recreational spot, Dr Thomson was instrumental in the initial development of the park. Originally, the park had only a sand beach, bathhouse, playground, 12 campsites, 64 cottages, and a 9-hole golf course. At that time, the lake was stocked with rainbow trout.<ref>{{cite web |title=Thomson Lake |url=https://saskregionalparks.ca/park/thomson-lake/ |website=Regional Parks of Saskatchewan |publisher=Saskatchewan Regional Parks |access-date=23 October 2022}}</ref>
The park is now 200 acres and has over 260 campsites with modern washroom facilities, showers, laundry, and potable water. There is also a BMX track, swimming pool, hiking trails, boat launch, filleting station, ball diamond, minigolf, and swimming lessons.<ref>{{cite web |title=Thomson Lake Regional Park |url=https://thomsonlake.com/ |website=Thomson Lake |publisher=Thomson Lake Regional Park |access-date=23 October 2022}}</ref><ref>{{cite web |title=Thomson Lake Regional Park, Saskatchewan Map |url=https://www.geodata.us/canada_names_maps/maps.php?featureid=HASXY&f=252 |website=Geodata.us |access-date=23 October 2022}}</ref><ref>{{cite web |title=Thomson Lake Regional Park |url=https://www.tourismsaskatchewan.com/listings/1629/thomson-lake-regional-park |website=Tourism Saskatchewan |publisher=Government of Saskatchewan |access-date=23 October 2022}}</ref>
