(1). Monthly feasible diversions were calculated as the lesser of the physical and legal availability at the Peterson Ditch headgate
the South Platte River(see Table A-3 in Appendix A)and the estimated available capacity for the Peterson Ditch
Ion
(see Table A-7 in Appendix A).For the years 1943-1949,the average available capacity for the Peterson Ditch for 1950-1997
was used because historical Peterson Ditch diversion data were not availalble
