First there are six main problems to be solved before our Indiana 
communities can protect themselves against floods. 
First PROBLEM. 
Flood Flow. 
First there must be proper information as to the amount of water 
carried safely in a channel. To determine this amount we must first 
know the rainfall that may reasonably be expected at a time not too 
remote, and the rapidity with which this rainfall runs down the watershed. 
In considering flood protection in Indiana we are barred at the out- 
set from a sure solution at present, first, on account of a lack of rainfall 
records over a sufficiently long time; second, by a lack of stream gagings 
to determine the amount of water which does run down our streams dur- 
ing heavy rains; and third, by a lack of surveys of watersheds. 
In other words, a heavier storm than any that has been recorded in 
the last thirty years of our rainfall records, may come in the future, 
but our records do not serve to determine the probable extent of this 
storm.
