In early May, we took a quick trip out to Soldan Lake, just north and slightly west of Stony Plain. Soldan is a pretty small lake (easily two laps in an hour) and is reasonably sheltered, making it a good option on a windy day or when the evenings are short.
The best access for hard-sided boats is on the SW corner of the lake just off Bridgewater Drive. It is just a short (10m) haul down a shallow slope and then you can slid in through the reeds. Parking is about 40m to the west (a small pull out that you will pass on your way in).
If you have an inflatable, you might be better off to park and walk up the ATV trail. It starts by the hood of my truck in the photo above and meanders maybe 40m to come out at the dock in the picture below (which you can also see in the distance in the very first photo). I didn't walk up this time but I recall the footing, especially by the dock, to be a bit uneven.
Once you are on the water, you can follow the shoreline around. It is mostly reeds with aspen in behind them. There are a few cabins but there is no other place to get out.
The lake is super quiet and too small for powered boats. There were a goodly number of birds here in May, including grebes, loons, ducks, geese, red-winged blackbirds, and a grackle.
The water was quite clear in early May and was probably okay for SUPs. There does not appear to be an inflow or outflow so it will likely get nastier as the summer goes on.
Oddly, we found two arrows hidden in the weeds by the public dock (one of the weirder finds over the years).
