OHIO. . 
Weather and Water Conditions 
This was an exceptionally wet spring and flood conditions were 
prevalent on most streams throughout June and July. This condition made 
it necessary to abandon the stream survey program during this year. As 
a result, the wood duck nest box checks are the only "indicator" to the 
trend in the production of this species in Ohio during 1958. 
Breeding Population and Production Indices 
There were 1,226 wood: duck nest boxes checked in Ohio during 
the Last two weeks of June. Of this number only 1,024 were in useable 
condition. Two hundred and forty-one (23.53 percent) were utilized by 
wood ducks for nesting. This is an increase of 21 percent over the pre-= 
vious year when the degree of utilization was 19.5 percent.
