Leadville Station, Colorado (H. D. Dean, Superintendent). 



In April, 1894, the United States acquired from John Law, Jennie 

 Goodell Blow, and J. B. Grant their rights in the water of Bock Creek 

 and their lakes and other property contiguous to the Government res-

 exceeding 500 gallons per minute from May to October, and an amount 

 of water from Bock Creek not to exceed 1,000 gallons per minute for

 brook, Loch Leven, black-spotted, rainbow, Von Behr, and yellow-finned.
