Section of Dam, Ballville Hydro-Electric Plant. Tlic work of developing this water poweras begun early in 1909, when the FremontT—.or & Light Co. was incorporated with ail of $l,000,0in». In the preliminary stage;i study and investigation was given toevations, dimensions, volume of dischargender variable conditions, and floods, and)nsidcrable outlay was incurred in securingle power and water rights. About 115 acresf river land with the flowage rights werejrchascd, including the sites of three millsid two tanneries. One of these known asle Old Stone Mill, ground away forore than 50 years, taking its power fromle old mill race. Meanwhile the market for PL.\NT. As originally planned and as constructedthe dam was 285 ft. long, extending from thesouth bank to a point which is now about themiddle of the river. From this point an earthbacked concrete wall or dike extended up-stream at an angle of about 45°, and met thenorth bank in a high hill. From the s
