6 27.4/ [73) RIVERS AND FLOODS
By H. C . FRANKENFIELD, Meteorologist
Rains were frequent and occasionally heavy during
the month of May over the t,erritory east of t,he Missis- i River, and as a result floods were numerous,
Y% t ough not of serious character, escept over the drainage area of the Potomac River. The floods were most prevalent during the second decade of the month and details regarding all will be found in the t.able a t the end of this report. Lack of space forbids a niore extended report. The Potomac flood occurred from May 12 to 15, and was most severe in the Shenandoah River and in the Potomac from Harpers Ferry, W. Va., to Washington, D. C. Above Har ers Ferry t,he flood proportions were much less than in % arch, 1934, ahhough the st,reets of Cumberland, Md., were again covered with water, with resulting damage of about $35,000. From Harpers Fen to Washington and in the Shenandoah River the

flood stage for so long that livestock could not graze in the lowlands, and but little planting had been done. Elsewhere the most serious aspect was the delay in farming operations. The flood in the Arkansas River began about April
39 in the vicinity of Wichita, Eans., and extended only to a short distance below Fort Smith, Ark. Floods in the rivers of Texas and in the Colorado River of Arizona were moderate. Along the Rio Grande in the State of New Mexico conditions were more critical, but fortunately the flood waters passed off without damage of consequence. As the deficiency in snowfall during the last winter had indicated, the annual rise in the Colunibia was very moderate, with no flood stages escept at a very few points. Even at these the crest stages were only sllghtly
above the flood stage. Losses for the month as reported aggregat,ed $1,118,500, of which about $1,000,000 occurred in tmhe Potomac River drainage area. Direct crop losses were not large (only 336,000 report,ed) but the indirect losses due t.0 delayed farm operations must have been very heav About
