CENTRAL FLYWAY 
NORTH DAKOTA 
Weather and Water Conditions 
Field conditions, Statewide were advanced during May. It was 
noted that extremes in conditions existed over the State. Field work in some 
sections was hampered by too much temporary surface water. This condition 
existed in the southeast and east-central sections of the State. Elsewhere, 
top soil moisture was needed. Several days of intense winds served to intensify 
the need for rainfall to an acute stage. Wind erosion more than drouth 
caused some reseeding. Damage to soil by winds was limited to areas of light 
soil. 
Relief came to crops and range land in late May and June. Light 
to heavy rains did improve the crop outlook. June was cool and shower activity 
continued to bianket the State. 
Local severe heil storms in some sections of North Dakota may have 
caused considerable damage to broods. 
Interesting to note is the increase of water areas per square mile 
in July 1958 compared to 1957. (See aerial data summary) Heavy rains in the 
East and Central Stratum gave temporary relief. Pot holes that were dry in 
May held some water in July. Late nesting, or broods may have been given 
relief in areas of critical water levels.
