Colorado Stream Update: The South Platte below Deckers is fishing fair to good with lower flows right now in the 85 CFS range. Look for the best fishing to be 150 to 200 CFS.

Current Conditions at Deckers:

It is spring time at Deckers with good hatches of midges, micro mayflies and early spring caddis. A good nymph fisherman will stick the majority of the fish right now but keep an eye out for risers in the slower pools and softer seams.

The fishing is great but the crowds close to Denver are thick! Flows have been stable and nymph fishing with small midges and mayflies is the name of the game. Look for ideal flows to be between 250 CFS and 400 CFS. Try tiny midge and mayfly imitations and 6x and 7 x tippets. Spring is the time of year to view wildlife! Look for Bald Eagles, Mule Deer, Wild Turkeys and other interesting fauna throughout the South Platte River drainage.  The fishing is good.  Clear skies and 52-55 degree weather. The water temperature was between 36-39 degrees and Slightly Off.
