We've got some 1/4 acre lots for sale in Joussard 1/4 mile west of the marina with underground power and municipal water and sewer. It's called Red Sky Grove - redskyalbertalimited.ca
We're also running Big Fish Bay RV park at the Slave Lake town limits -bigfishbay.com- with seasonal lots for rent.
I'm trying not to 'advertise' on here, so PM me with questions...
Like tuffyy said, this lake is unpredictable with weather, depths, and traffic. But on the flip side, it's clean, full of fish, accessable, and generally not full of people like some other sport lakes in this province.
I hope to see you this summer at the lake, Shane.
