50 The Boulder Canyon Hydro Plant was substantially rebuilt in the mid-1930s, with the installation of new generators, circuit breakers, and control panels. The new generators doubled the capacity of each unit to 10,000 MW, and the total modernization project cost $287,000. Much of the equipment from this period continued to operate until the next major renovation in 2011. 101
ADDITIONAL WATERSHED DEVELOPMENTS After City officials suffered through numerous water quality problems with the City’s early water system, one of their major concerns was to assure that the water in Boulder’s Silver Lake Watershed remained (nearly) pure. On July 23, 1914, Mayor W.L. Armstrong, City Engineer H.E. Phelps, Consulting Engineer M.C. Hinderlinder, six aldermen, the city health officer, and newspaperman Otto Wangelin piled into one large Stanley Steamer and drove to Silver Lake for an inspection. 102 Twenty-five species of trout had been identified in the watershed, and the area had become a tremendous attraction to Colorado fishermen. After the field trip, the council discussed the need for a guard for the watershed, or, at least, the possibility of hiring a caretaker for the premises. Shortly afterwards, the City hired its first caretaker, Alfred T. Wheeler to make releases from the reservoirs, but also to keep an eye on recreational users of the area to assure no polluting activities took place. 103 Silver Lake’s first caretaker, Alfred T. Wheeler, posed with some of the trout he had caught in the lake. Carnegie Branch Library for Local History, Boulder (Carnegie 513-2-26 #1). 51
