sank below the crest of the dam and remained below until July 6, reaching its minimum (5.7 feet below the crest on July 1. It gas also below the crest from August 6 to August 25 and from September 10 to September 22. This condition was sufficient evidence that the minimum flow could not furnish even 900 horsepower, while 5,227 horsepower had been counted upon. It was apparent that much of the inflow was lost by evaporation, the area exposed to evaporation being 3 square miles and the low level occurring during the hottest part of the summer.

Notwithstanding this evidence that the river could not, during certain seasons, furnish power for its existing load of water, lights, and motors, early in 1897 the Rapid Transit Street Railway and the Dam and Suburban Railway were added to the list of power consumers. After that the energy developed by the water power was

utilized

• (1) in pumping water,
• (2) in furnishing light to city and citizens,
• (3) in running the Rapid Transit Street Railway,
• (4) in running the Dam and Suburban Railway, and
• (5) in running the motors of various users of power in the city-such as for planers, printing presses, etc.

To supply all of these demands required a total average of 1,000 horsepower.

On July 4, 1897, the water again dropped below the crest of the dam, but it flowed over again on July 17. It was also below a few days in August, October, and November, and the whole of December. On January 1, 1898, the water was 2.3 feet below the crest, and it did not again flow over until April 13. The lake level was below the crest part of the months of August and September, and it again dropped below on October 10 and continued below until April 20,'1899, reaching a depth of 10.68 feet below crest on March 29. From March 15 to April 17 it was more than 10 feet below the crest. It again dropped
