This is a rough idea of what
I THINK we could/should consider as a state. It sure isn't going to please everyone and this was the first I'd thought about it, but it provides 4 zones in the state, so I believe we would lose the ability for any sort of a split (but I may be wrong?)
With a liberal, 60 day season, it could look like this (5 day early season still stand): Duck Season
North Zone Early: October 15 - December 8 (55 days)
North Zone Late: October 22 - December 15 (55 days)
South Zone Early: October 22 - December 15 (55 days)
South Zone Late: October 29 - December 22 (55 days)
But where this really comes into play is if they move to a restrictive season - which, with the rate of CRP loss, coupled with the fact that we're due for a drought period, is bound to happen in the not to distant future.
The current Iowa structure would be almost guaranteed to look something like this, give a week or two:
N Zone: October 15 - November 15
S Zone: October 22 - November 22
With the zone structure I showed, it could look like this:
N Early Zone: October 15 - November 15
N Late Zone: October 29 - November 29
S Early Zone: October 22 - November 22
S Late Zone: November 7 - December 7
That would give us nearly 55 days worth of hunting throughout the state vs. 37ish with the current structure, not to mention a much better chance of hitting peak migration numbers in different parts of the state.
The river corridors historically hold greater numbers of birds later into the season, which 1) are difficult to count and 2) at this time aren't counted at all. The hunters that actually hunt these areas know this - the DNR wishes to ignore it. So why not put a 10-15 mile corridor on either side of the river for the bottom 2/3 of the state to accomodate those hunters that frequent those areas. To my knowledge, there are few marshes within most of those corridors that would freeze early. There certainly are a few - but not like the remainder in the state.
Like I said - this isn't perfect, but it's based off the Nebraska idea and give us something to at least discuss positives and negatives.
