Flow at the gaging station <br />Arkansas River near Portland was 711 cfs, as compared to <br />the long-term average of 368 cfs. Storage in lurquoise, <br />lwin Lakes, Pueblo, and John Martin reservoirs totaled <br />100% of normal as of the end of March. <br /> <br />Outlook <br />10tal distributed reservoir storage following the <br />Pueblo Winter Water Program was 153,035 acre-feet, <br />including 53,237 acre-feet in Pueblo Reservoir, 77,075 acre- <br />feet in off-channel reservoirs, and 22,155 acre-feet in John <br />Martin Reservoir (after distribution to accounts).
