APRIL, 1910. MONTHLY WEATHER REVIEW. 661 RIVERS AND FLOODS. By Prof. H. C. FRANKENFIELD. in charge River and Flood Divlsion. The rivers were unusually quiet for the month of April. although the precipitation was sufficient to have caused floods in many of the rivers under ordinary circumstances. As it happened, the early disappearance of the winter SIIOWS froin the watersheds of the northern rivers, the general ahsence of rain during the month of March following, and the freedom from severe cold conibined to render the soil dry and soft, so that a niuch larger percentage than usual of the copious April rains was directly absorbed, and the rivers, as a rule, eshibitetl a falling tendency. There were, however, several sharp rises during the early portion of the second week of the month in the rivers of Tesas and southwestern Arkansas, including that portion of the Ret1 in the latter vicinity. These rises were clue to heavy local rains and, although advisory warnings of their coining were issued, they were not of sufficient magnitude to cause trouhle beyoiicl that incident to the temporary removal of cattle and portable property. The prolonged rain period that prevailed over the Atlantic States during the latter half of the month was responsible for some decided rises in the rivers of the Atlantic States, but no tlaniage of conseqiience resulted, except along some of the streanis of the State of North Carolina, where the losses were about $50,000, chiefly along the Tar R.iver and its tributaries. Rurnings mere issued in ainple t.iiiie and propert,y to the value of $40,000 was rttport.ec1 as saved. In t,htt North Atlantic States no t lainage was done except lorally along some of t.he smaller st.reams of mest.ern New York. The rivers of the Pacific syst.em were unusually low owing to t,hc early disappearance of the snows and the absence of heavy rains. The annual rise of the Colunihia River began about the niiildle of t,he month. Hyclrographs for typical points on several principal rivers are shown on Chart 1. The stations select.etl for charting are Iieokuk, dt.. Louis, Memphis, Vicksburg, and New Orleans, on the Mississippi; Cincii1nat.i and Cairo, on the Ohio: Nashville, on t,he Cumherland : Johnsonville, on t.he Tennessee ; Kansas City. on the Missouri; Lit.t.le Rock, on the Arkansm: and Nireveport,, on the Red. - . - . .- __ . - - - SPECIAL PAPERS ON GENERAL METEOROLOGY.
