On another forum someone had asked what effect the flooding along the Illinois River may have had so I looked into that. "look at habitat in counties where harvest went down significantly. Spring flooding affecting birth ? I know along the Illinois River for the last ten years it has seen massive flooding well into the time period they should be having fawns." I looked into that for the 2 seasons prior to the significant deer harvest drop vs. the 2 years of deer harvest drop. Here is what I found.

Illinois River is 273 miles long, running through or bordering 17 Illinois counties.

These measureable losses in deer harvest only account for about a third of the state's loss so I believe it is a significant factor in explaining the decline in deer harvest but there are other factors.
