August on the spring creeks is not the most desirable time to fish them. Unless you know the creeks really well---as well as our guides---the fishing on the creeks takes some patience. Terrestrial fishing is OK with beetles and ants for those anglers willing to stick with it. Make sure to have patterns from size 18-24 and also imitations of the nymph, emerger, cripple, dun and spinner as the trout are very selective. Nymphing midge larva and sow bugs in the morning always produces. PMDs have pretty much stopped until next year so dry fly purists that love the spring creeks are waiting until the fall for Blue Winged Olives.
The two main creeks we fish are Armstrong's and DePuy's spring creeks near Livingston and Bozeman, Montana. These creeks are private and do require a rod fee, but, if you enjoy sight-fishing to rising or shallow water feeding trout, the spring creeks are an exciting place to get in some sight-fishing to trout on small waters.
If you are looking for some places to fish this spring near Bozeman or Big Sky that offer consistency when some of the larger rivers do not, consider the spring creeks. The consistent flow of the spring creeks mean water temps are the most conducive to find feeding trout when other rivers and creeks may fluctuate on a daily basis. The consistent water temps produce a higher metabolism in spring creek fish than trout in other waters and gives anglers a better chance to hook up.
As a rule we use yarn indicators on spring creeks – generally custom cut to be just big enough to not sink. These indicators allow you to detect very subtle disturbances resulting in more hookups. Most trout are going to be selective and eating midge pupa or emergers or mayfly nymphs, emergers, or dries if you are lucky. The exact fly isn't always key, but something that is tied well, tied sparsely, and in the right size is more important than making sure you have "that one hot pattern." Where you fish and your presentation is much more important than changing out lots of flies.

The Month Ahead:
Terrestrials will rule the roost in late August and September. Tricos are also important in the early morning, especially at the MZ ranch. Spring creeks are tough but always have cold water and are a nice mid summer option - the trout are always there and feeding but they aren't as reckless as they were during the PMD hatch so you have to earn each one.
Long Term Fishing Forecast:
The spring creeks are always a safe although technical option. Water temps are always cold even on the hottest days and the fish are loaded in the creeks. In the fall some of the weeds die back and the baetis hatch can be awesome in October, especially with some cloud cover.
