As the colony's engineer-in-chief, Nettleton laid out the town, surveyed the farms, and planned the irriga- tion system. In March 1883 he was appointed state engineer of Colorado, an office he held for four years. During his first year in office, he designed a current meter. In his biennial report for 1883-84 he remarked: At first the Fteley current meter was used for measuring current velocity, but it was soon apparent that this instru- ment was entirely too delicate for the rough torrents, filled with drift of all sorts, in which it was necessary to use it. An instrument was designed by me more suitable to the icork [named the "Colorado" current meterY a description of which is given elsewhere. The main object kept in view in designing this instrument, was to make it self-clearing, the great defect of the Fteley meter being its liability to error from clogging with grass, weeds, etc. which at times would vitiate many hours' work .... Three "Colorado" meters, having been made for this department by W. E. Scott & Co. of Denver; these instruinents have since been in continuous use in gauging rivers and ditches giving entire satisfaction. Photographs of Nettleton and of one of the current meters built by W. E. Scott & Co. are shown in figures 12 and 13 respectively. In addition to having been referred to as the Colorado and the Scott current meter, these or very similar meters also have been called the Nettleton meter, after their designer; the Lallie meter, named after one of its later manufac- turers ; and the Bailey meter, which was named after an associate of Lallie's who worked out the design wherein the exposed counting wheels were placed within a glass-covered enclosure.
