Any water sources around Black Elk Peak, SD?

[u/Quick_Chest_1165]

I'm putting together a backcountry trip to the Black Hills with a younger scout troop some of whom are new to the backcountry. Trip is in mid-June. I want to have flexibility in the itinerary so we can go as slow or as fast as they end up caring to. Black Elk Peak seems good because its dispersed camping plus lots of trails. The only x-factor is water. In the lower areas the creeks seem to be robust, but what about as you get nearer to Black Elk? Like on Lost Cabin Spur #2, or the upper parts of Grizzly Creek #7 or Norbeck #3? I can put a number of loops together with a stop nearer to Black Elk Peak, but curious if the upstream ends of the creeks that show up on the map will actually have running water?

There's a reservoir at the top of the mountain by the fire tower. Requires filtration.
