Cache-Landmark Engineering was requested to review North Logan’s current water rights and sources, and to recommend improvements and/or ordinances in order to meet future water demands in the year 2020. Currently four wells plus a group of springs in Green and Water Canyon supply culinary water to North Logan. The average daily flow (2002) is approximately 860 gpm. The projected average daily flow is 1,569 gpm in the year 2020 (see Table 4). Therefore North Logan needs to be able to provide an additional 708 gpm by 2020. The water rights for the four city wells are 6.35 cfs (2,850 gpm) (see Figure 1). The capacity of the wells is 5.59 cfs (2,507 gpm) (see Table 9). Thus the capacity of the wells is 0.76 cfs (342.9 gpm) below their current water rights. North Logan’s spring water rights shows the springs are combined into three water right
