Beautiful mountain lake
Only a few miles from Ft. Garland, Mountain Home Reservoir is another Colorado State Wildlife Area, but no signs saying an SWA permit is needed to camp there so not sure if you need one or not, we have it so we forgot to check. We have also bought land to build on three miles from the lake, we love this area.
There are two sides to camp on, one side has toilets, vault style, but it's more crowded on that side and less room to camp. The other side takes a little drive, but is much more open and has the mountains behind you and the lake in front of you. It gets busy on weekends, but weekdays are pretty quiet.
The water is cold, but you could swim in August if you really want to, not too cold at all. Boats are allowed, and there boat ramps on both sides of the lake from what we could see, didn't inspect the ramps, but know one works because there was a pontoon boat on the lake one day.
The weather changes by the minute it seems, and storms move over the area pretty quickly. If you don't like the weather wait five minutes, it'll change, and I'm not exaggerating. Still mostly nice weather, and normally sunny.
This is a beautiful camping area, again this is a no hook up area so pack in what you need and leave no trace. Try to camp near one of the already made fire pits, makes it easier on you and they discourage building new fire pits. If you don't want a fire then you can camp anywhere you aren't blocking a road.
Truly beautiful place to camp, you can stay 14 days in a 45 day period. RV dump and fill stations are nearby in Ft.Garland, and it's only about thirty minutes to Great Sand Dunes National Park, and Zapata Falls. Smith Reservoir is also nearby and that's another SWA we reviewed, check that one out.
