Olives over and over again but not the Big One

The Olives are still getting started (they have been on for months), we have not seen the main blanked hatch but with Spring Creek at 51 degrees and the air temp matching it, not long to wait. I'll bet it will be on Saturday Feb 26th, it's to snow,rain and generally be a bad day, just perfect. They were going strong at 11:30 and lasted till 2:30 PM on Thursday Feb. 23 some flashy takes and some good head and tail risers the kind of hatch that makes you really appreciate your day. Again only needed "1" fly, just had to line it up and float it over them till they wither took or I missed. Attached it a short video showing the perfect Olive water, enjoy it. This has been going on for months but not stream wide, it has been on very specific areas and you'll have to look for them and not expect that the hatch will occur where your at.
