I see there are a few guys asking about Sprague.
Sprague lake is a great fishery and there are a few tricks you may want to try.
Walleyes in Sprague feed on Crawdads allot,more so than anywhere else that I fish for them.Use Crawdad crankbaits and fish them shallow.Many times I catch eyes in 2 or 3 feet of water.Another good Crankbait for Sprague is the Firetiger Shad-Rap,#5 or #7.I do very well with the Crawdad cranks on the tops of the points and I like the Shad-Rap on the flats.
I also like to fish Sprague with jigs.
Sprague has some great Mayfly hatches during the year and this is a great time for jigs.Not the big 3 and 4 inchers.Small Crappie jigs.I like the Culprit tube or the Kalins twister tail.
I have been useing the tri colored twister tails by Kalins at Sprague with great success for many years now.Fish them just like the bigger jigs that are used at Roosevelt with the exception of the weight,1/16th to 1/8th oz.
The Culprit tubes work very well under a slip float with a Leech or a crawler.
