Nymphing a limestoner is always the default technique. Day in and day out, the fish just feed better on the bottom than on the surface. For Spring Creek sowbugs and shrimp (scuds) are 24-7-365 flies, patterns that work virtually year round. When water levels are favorable, a Zebra Midge behind a sowbug or shrimp is always productive. Dark Sulphur Nymphs and Walt's Worms match the underwater stages of the predominant hatching insects.
