The rainfall in this part of the country is very constant for eachyear,that is, it has it lov; v/ater and its high water periods just aboutthe sane time each year,and the conditions that are to be met can heprepared for. Radical changes are not apt to come about,and this is a thingthat can not be said for other sections of the country. The evaporation in this part of the country is rather excessiveduring the year.Later the evaporation v;ill be calculated theoricallyand then this result v/ill be compared with that of the actual results betveenthe years 1884 and 1904.

a Rainfall, At Otta.va Illinois the goverment has kept a station for severalyears. The gage height of ths riyf^r has been recorded .-^hereby gining thecalculations for discharge. If the cross sectional area of the river isknown then the discharge and the velocity can be calculated. Thegoverment data gives values for the amount of run-off per square mile nd also the depth of the run-off in inches for the different months ofthe year. Thru out this part of the country the mean annual run-off isfrom ten to .fifteen inches per year. In the foregoing pages on locationthe evaporation of this part of the country was calculated. It vras foundthat the annual evaporation v/as about 21.5 inches and that of the runoffv/as something over 13 inches. The most extensive data wac taken by the United States in the year1903. Most of the calculations for this design vrere based on the data ob-tained during this year. Since the rainfall is practically the same forall the years that have been recorded,and t
