A &scrip- tion of the antecedent conditions as well as cletailed data for the month of January will be found in the report of District No. 11 in the Monthly Weather Review for that month and need not be repeated here. It is well to note, Lowever, that the aver e recipitatioii in the 13.20 inches, or 7.79 inches above the normal amount, while snowfall to the amount of 400 inches was reported at Tamarack, Cal., with a total water precipitation for the month of 39.80 inches. State of California for the mont T Y 1 o January, 1911, was 'official in charge of the loca Y ofice of report on the floods was pre ared by at sacramento, Cal.: Until about January 12 all streams in the central valleys of California showed little departure from the unprecedentedly low stages that had been general during the st few months, but on the date referred to the Sacramento River b z w Redding, and the eastern tributaries of this stream, began responding to the rains that revailed throughout the Sacramento watershed from the 9th to 15t1, inclusive. While the rains of the San Joaquin watershed were practical1 identical with those of the Sacramento little effects were noted in t i e stages of the rivers in the section first named. By January 17 a general fall was in progress throughout the rivers of both watersheds. but the heavy, warm rains that occurred between January 18 and 21 resulted in rapid rises in the Sacramento, American, Feather, and Yuba rivers, and increased the run-off of the tribut,ariee of the San Joaquin. 20 advisory messages were telegraphed to points on the Sa%i%?%iver between Colusa and Knights Landing indicating the approach of a heavy rise in the river during the next two or three days. By the morning of Januar 31 the Sacramento at Colusa had risen to a stage of 19.4 feet, a rise otover 14 feet in 34 hours, and by the mornin of January 22 the river at Knights Landing had risen to 13.4 feet. Aeavy rises also occurred in all the eastern tributaries, except Pitt River, with fresheta in many of the smaller forks of the Feather- Yuba system. h m January 24 until February 1 general and heavy rains occurred mer both watersheds, and during the greater part of this period rain fell heavil along the western flanks of the Sierra Nevadas as high as the 5,000-&ot level, melting a large amount of the snow t.hat had accumulated since January 9. On January 24 warnings of heavy rises were telegraphed t,o Bel1ot.a and Stockton for distribut.ion to points along Mormon Slough, a.nd by the evenin of January 25 this stream had overflowed it.R banks between Linden an8 Bellota, inundating several thousand acres of farm land The Government Draina e Canal, which diverts t,he wat,er of Mormon Slough back into the Ca%veras River below Stockton, protected the cit of Stockton from overflow. 8n J a n 7 28 advisory meam s were tele phed Colusa to the effect that a1 new levees should r e watched E n g the next two or three days, and on January 29 this advice was also telegraphed our observer at Knighta Landing and @veri verball to the official in chrvge of the Sacramento levees. This advice was Lllowed in all cases, and it haa been stated that some of the new levees, that had not been tried since their construction after the floods of 1909, were probably saved aa a result of the warnings. On January 30 it became evident that the heavy rains and rapidly melting mows would result in critical conditions in the lower Sacra- mento Valley between Colusa and Walnut Grove and that serious floods would occur in the valley of the Son Joaquin. On the morning of this date advisory messages were telegraphed to points on t,he Sacra- mento indicating heavy rises between the mouth of Stony Creek and Sacramento City, and warnings were wired to Stockton. Bellota, and Galt to the effect that dangerous floods would occur in the vicinity of Stockton, along Mormon Slough, between Linden and St,ockton, and over a large sect.ion of the country contiguous to the junct.ion of the Mokelumne and bsumnes rivers. During the afternoon of January 30 general flood warnings were imsued for the San Joaquin River from the mouth of the Calaveras northward to Mendota and Firebaugh indicating heavy and dama.ging floods for all lande eubject to overflow between those points. By the morning of January 31 the Sacrament.0 River waa dangerously high from Monroeville to the mouth of the American, and critical stages were reported from many points in thc Bet. 4.2 10.2 20.0 13.3 19.8 8.9 18.5 14.8 34.3 17 3 36:9 10.1 FEBBUABY, 1911 JSn. 30 Jan. 31 ... do .... ... do .... ... do .... ... do .... .. .do.. .. ... do ....

By the afternoon of this date over 10,OOO acree of land were overflowed in the vicinity of the junction of the Mokelumne and Coeumnee riverR with the combined overflow of these streams rapidly backing up along the east Ride of the Sacraniento River, and it has been eRtiniated that an area ctiinprising 76,000 acree was under water between the junction of the C'alaveras and Mormon Slough and the city of Stockton. At this time the flood waters of the MerceJ, Stanislaus, and Tuo- lumne rivers had reached the San Joaquin River and an immenbe flood wave was moving rapidlv down this stream. This flood reached the lowlands in the vicinity of Lathrop and San Joaquin Bridge by the morning of February 1, and by night of that date many levees had given way and man thousands of acres were flooded. The river observer's house. 1ocateJnear San Joaquin Bridge. waa washed away, and many other residences in that vicinity were either washed from their founda- tions or else undermined by the water. By romptly spreadin the warnings sent from this station the Lathrop oEserver saved hunireds of head of valuable stock. About 10,000 acres.were flooded in the vicinity of Firebaugh and Mendota, mostly the property of the Millex & Lux Co., but the warnings sent to the agent of this company gave am le time for the saving of all stock. 8~ the morning of February 3 the flood had spread over a large territory between San Joaquin Bridge and Roberta Island, destroying many miles of levees and inundating thousands of acres of reclaimed land. and considerable water had backed into Stockton from the lower Calaveraa and from the overflow of Mormon Slough. canal, mentioned in another art of this report, undoubtedly save! Stockton from a damaging floocf aa the floods in the surrounding country were the most disastrous and widespread ever recorded in the San Joaquin Valley. It is estimated that nearly 300,000 acres of land were under water from the night of Januar 31 until February 3. On the morning of Felruary 2 the water had commenced to subside, but it was not until February 5 that normal conditions prevailed. Advisory mesaages were sent to the lower island districte indicating that all levees should be gatrolled, but with the exception of a rise of about 3 feet the delta Ian s showed little effects of the floods that pre- vailed above, which is probably due to the fact that the flood waters spread over such a large area and that much of the overtlow waa im- pounded, so that the run-off was gradual, especially between the mouth of the Calaveraa and Antioch. It is gratifying to be able to state that warnings were received a t all oints affected by the floods in ample time to guard against danger and f;amage. and that many thousands of dollars' worth of stock were saved and levees protected aa a result of the warnings.

On the Pollowin da warnings were issued for a still hi her stage at %itts%urg and for tl. stage of 39 feet at deeling, W. Va., but the freezing temperatures 'that set in during the afternoon checked the rise from the tributaries, and the crest stage at Pittsburg was but 25.2 feet, or 3.2 feet above the flood stage, at 7 a. m., January 31. At Wheeling the highest &age was 35.2 feet, 0.8 foot below the flood stage, at midnight, January 32. The flood was very severe along the Monongahela River, and has been esceecled but once during the winter months. Some crest stages were as follows: Fairmont, W. Va., 29.2 feet, 4.2 feet above flood stage; Greensboro, Pa., 32 feet, 14 feet above flood stage; and Lock No. 4, Pa., 36.7 feet, 8.7 feet above flood stage. .The warnings proved to be very timely, and the esti- mated losses from the flood were consequently quite small.

In the Parkersbur district tlie crest st es were 36.3 and 45.4 feet., 6.4 feet above the flood stage at Point Pleasant, W. Va., on Februa 1, and a t the latter place February 3, inclusive. The usual warnings were issued, and no damage was done in the district. From Huntington, W. Va., to Louisville, Ky., flood stages were not reached although they were closely a proximated, except at Madison, Ind., and Louisville, I&. Below Louisville flood stages were exceeded as far down as Shawneetown, Ill., but no damage was done. The usual warnings were issued at the proper time, and the highest stage reached was 3S.S feet at Evansville, Ind., 3.8 feet above the flood stage.

There waa a inoderate flood in the lower Tennessee River, due to heavy rains from February 6 to 9, inclusive, and warnings were first issued on Februar 11. The little or no damage was done. The crest of the Ohio River rise passed into the Mis- sissippi River on February 14, and reached New Orleans, La., on March 3 with a stage of 11.8 feet. Severe floods occurred in the smaller streams of north- western Illinois and northeastern Iowa from February 14 to 18, inclusive. There were from 8 to 10 inches of moist snow on the frozen ground, and high temperatures from February 10 to 12, inclusive, followed by heavy rains on February 13, 14, 16, and 17, sent most of the snow into the rivers. The trouble was confined prin- cipally to the rivers that have their outlets between Dubuque and Daven ort, Iowa. The Galena River of 1892, while in the Maquoketa River of Iowa the rise was the most rapid ever known, with a crest stage at Maquo- keta, Iowa, short1 after midnight on February 13-14, about 8 inches hig Y ier than the high-water mark of June, 1592. The waterworks plant was put out of commission and several small bridges were washed away. The most serious damage occurred in the bottoms. along the Wapsipinicon River. One human life and 73 head of cattle were lost and several bridges were carried a-w~~y. These floods caused a marked rise in the Mis- sissippi River, and flood stages were almost reached between The mid (i! and rainy weather that prevailed during the early part of the month carried awa rises in both the Saginaw and Grnncl River watersheds. For a few da s conditions were quite threatening, as were feared. A gorge 4 niiles in length formed in the Grand River during the afternoon and night of February 20 just below tlie city of Portland, Mich., and the back- water reached the flood stage on the following morning. Some clamage was done to basements, but the gorge was successfully dynamited during the afternaon, and the waters afterward receded rapidiy. There were also fears that cold weather would form a gorge in the low stretches of the river just below Grand Ra ids, and on Weather Bureau a large boom was stretched wrow the river just above the city on February 21.
