Sandy will be a wild card this year. First of all we need a good flush of H2O to clean out some of that silt, maybe this weekend. A few days of 4-5K cfs would help.
I can't tell you what to expect for steelhead. This year is the first season where no hatchery plants from other streams will be returning. All the fish will be broodstock and I have yet to get the numbers of clipped fish for this run.
Your typical Sandy wild run is a later returning fish, Feb.-early April are best. Jury is still out as to how this affects the broodstock fish. For some reason broodstock fish in other streams do not always show at the same time as their genetically similar bretheren but for the most part they will be there when expected.
I have caught wild Winters on the Sandy as early as late Oct. and fairly consistently throughout Dec.-Jan but it's nothing like what you will see in March.
The only way to know is to go, I know a few fish have been caught already, wild and clipped.
I suspect the crowds on the Sandy will be thin this year when compared to the last few years. People who only want to take fish home will go elsewhere.
I hope for a great return of fish that can be BBQ'ed or gently released.
You can catch a Sandy fish on anything you catch them on elsewhere, the biggest part of the equation is being where the fish are. Just keep at it.
