 outlet to head is fully 45 miles. In circling this lake the distance traveled is 

 estimated at 160 miles, not counting side trips up tributaries. In the lake are 26 

 islands, of which three are grass islands and showed evidence of being vast 

 breeding grounds of gull and tei'n. '^wenty-three tributaries enter the lake, 

 four of which have their origin in tributary lakes. Eight tributaries are
