OHIO 
Weather and Water Conditions - 
| This was an exceptionally warm, wet spring with intermittent flooding 
common on most streams throughout the State. Inland lakes and ponds carried 
a higher level of water than any spring during the past five years. Many nests 
and eggs were lost in the Lake Erie marshes during May when the majority of — 
this area was inundated by storms. In general, this was a poor season for nest- 
ing of the ground nesting species but a very good year for rearing of all waterfowl.
