- 5 - is in the process of developing its own augmentation plan and may not rely on the District's plan in the future. Nearly all of the plan members within the Left Hand Creek and James Creek ISF reaches occupy their cabins seasonally. If the Town of Ward's depletions are taken out, the plan members' depletions in the Left Hand Creek and James Creek ISF reaches during the winter months, when the reach is historically stressed, are very low (the average depletion rate is 0.0035 cfs). The historical streamflow records indicate that during the months of November through April, these ISF reaches are most likely to have flows less than the decreed ISF rates. The District's engineer, Mark McLean, reviewed the historical daily streamflow record for the gage on Left Hand Creek near Boulder, which has a sporadic record with continuous daily data for May 1929 - September 1931, April 194 7 - December 1953, October 1955 - September 1957, and October 1976 - September 1980. These gage records indicate that historically, the Left Hand Creek and James Creek ISF water rights have been satisfied from May through August. The average amount of days the Left Hand Creek ISF water right would have been unsatisfied during the 1951- 1980 period for the months of October - April was approximately 10 days per year. During September and October, plan members' average daily depletion rates are 0.035 cfs and 0.016 cfs respectively. The streamflow records show that the Left Hand Creek and James Creek ISF water rights were satisfied every day in September for 11 of the 16 years in which records were kept and were satisfied every day in October for 13 of the 16 years in which records were kept. Replacement Sources to Left Hand Creek and James Creek The District utilizes its Left Hand Ditch Company shares to augment depletions by its members in the Left Hand Creek basin. Four sources of Left Hand Ditch Company water are released into the drainage. Two year-round direct flow rights diveli out of South St. Vrain Creek and are discharged into the headwaters of James Creek. This water then flows through the James Creek and the Left Hand Creek below James Creek ISF reaches. Releases from Lake Isabelle are also divelied into James Creek through the Ditch Company's South St. Vrain Creek diversion. Releases from Left Hand Park Reservoir to Left Hand Creek flow through both Left Hand Creek ISF reaches. Releases from Gold Lake to Left Hand Creek flow through the ISF reach below James Creek. Operationally, the Ditch Company usually opens the gate to Lake Isabelle at the beginning of August, and does not close the gate until the reservoir is emptied, which typically is by September 1. Once Lake Isabelle is empty, the Ditch Company starts releasing water from Left Hand Park Reservoir and continues such releases until winter weather makes access impractical, usually in late September. The Ditch Company provides water to the District from Gold Lake in winter and spring, and also to augment stream flows in August and September. Releases from Gold Lake flow through the J ames Creek ISF reach and Left Hand Creek below J ames Creek. Terms of Proposed Stipulation and Decree The CWCB staff expressed concerns to the District about the potential to add new members along Middle St. Vrain Creek and Left Hand Creek to the District's plan in the future, which would result in additional unreplaced out-of-priority depletions. To address those concerns, the District has agreed to restrict future membership on Middle St. Vrain Creek and Left Hand Creek to those new members whose diversions deplete on or above those reaches prior to December 23, 2002, the date of the filing of the application, or to those new members who can contribute new water to the plan that would cover the new out-of-priority diversions in time, place and amount.
