Importation from outside the natural watershed was considered <br />and included as an additional 4.23 square miles. The Pleasant Valley and <br />Lake Canal as well as the Larimer County #2 Canal were used to import <br />this water. The study places a 100-year storm on the basin and when <br />importation was included, a flow equal to a 25-year storm was carried <br />by these canals to Spring Creek from outside the basin. <br /> <br />A 25-year storm of 2.45-inches was assumed for computation of the 25-year <br />runoff shown in Table 4. Rainfall intensity curves, information on the <br />100-year design storm, watershed characteristics, 100-year hydrographs, <br />canal inflow hydrographs and the summary from the report are included <br />here. <br />
