f <br /> SOUTH PLATTE BASIN <br /> Basinwide Conditions Assessment: <br /> The SWSI value of 3.8 indicates that for September SOUTH PLATTE RIVER BASIN <br /> he basin water supplies were well above normal.

UONTW rEAp <br /> Outlook <br /> Irrigation users curtailed their use in the month of <br /> September as crops began reaching maturity. Except for some <br /> minor applications, irrigation was finished by the end of the SOUTH PLATTE RIVER NR. KERSEY <br /> month. Stream flow conditions continued to be above average 2.8 F`Dw WATER YEAR <br /> for September due to continued return flow and reductions in 2.6 <br /> irrigation, resulting in a relativly junior call on the South 2" <br /> 2.2 <br /> Platte mainstem. The call below the metro area was % 2 - - <br /> completely released on September 12, which is earlier than : 1.8 - <br /> most years. By the end of the month the call above the metro o <br /> Sr_ 1.4 _ <br /> area was for municipal storage as is usually the case when > ,.2 _ <br /> direct irrigation stops. 1 <br /> The free river conditions downstream of Denver has 1 0 8 • u. <br /> 0.6 <br /> allowed storage and recharge to occur.

Reservoir conditions along with good <br /> stream flows bode well for next year's irrigation and municipal <br /> supplies.
