Regional draft-storage relationships for central and western Upper Peninsula of Michigan

Regional draft-storage relationships for central and western Upper Peninsula of Michigan are presented in this report. Storage requirements for the 5- and 20-year recurrence intervals were determined using the frequency-mass curve method and daily discharge records from 15 gaging stations. The relationships will be useful in making preliminary estimates of development potential and inc comparing the development possibilities of different streams.

Carryover storage was investigated and was found to be unnecessary at draft rates of less than 50 percent of the mean annual flow. Carryover storage requirements are presented for the gaging station Middle Branch Escanaba River near Ishpeming.
