They're really not all that much higher if at all. If you're looking at the weekly hatchery returns on the WDFW website, those numbers don't actually reflect how many brats are in the river. I feel like a Reiter, Fortson, or Cascade bound fish has a higher likelihood of never making it up into the ponds. For instance, on the sky, when Hogarty Creek is low or they've shut the gate, the fish stack up and those Reiter guys are pretty efficient at hitting 'em. Tokul fish are pretty likely to just shoot up the creek. I could be wrong, though. If there was harvest data available newer than 2003, one could probably add the harvest numbers to hatchery on hand numbers to get the true hatchery escapement.
