PHYSICAL INFORMATION <br />Berthoud Pass Ditch originates in Water Division 5 District 51 in Grand County and terminates <br />in Water Division 1 District 7 in Clear Creek County. <br />Construction of Berthoud Pass Ditch began in 1909. <br />The Ditch has been in continuous operation since <br />1910. The Ditch was historically used to provide <br />irrigation water to the east slope. <br />The Ditch intercepts water from First Creek, Second <br />Creek, and Current Creek as it winds its way along the <br />east slope of the Continental Divide. At the Berthoud <br />Pass Ski Area, a short tunnel carries water under the <br />parking lot. In 2000, several sections of the pipeline <br />were replaced. In 2004, the pipe section under the <br />parking lot was replaced. <br />,~ <br />~; <br />Berthoud Pass Ditch is transported through <br />a small tunnel under this parking lot <br />Length: Approximately 3.5 miles <br />Capacity: At least 31.0 cfs (31.0 cfs reported on June 30, 1998 was the maximum daily <br />diversion reported for the available period of record. A maximum daily diversion of 47 <br />cfs was reported in 1997, however, during conversations with State Hydrographer Bob <br />Cooper it was learned that this diversion was reported in error.) <br />Diversion Measurement Device: <br />DWR WDID: 5104625 <br />USGS ID: 09021500 -Berthoud Pass Ditch at Berthoud Pass, CO. <br />Datum: 11,290 feet above sea level NGVD29 <br />Ditch Outlet: 2.5 foot by 9 foot cut throat flume equipped with a Stephens recorder and <br />satellite monitor. <br />Conveyance Efficiency: Most of the Ditch is lined. A limited portion of the Ditch is earth <br />lined. <br />HydroBase Data: Diversions are reported as continuously monitored streamflow records and as <br />administrative records by Colorado DWR. Continuously monitored streamflow records <br />for Station 09021500 are available on a daily and monthly basis from prior to 1950 <br />through water year 2002. <br />Available diversion data for Berthoud Pass Ditch was reviewed and compared to identify <br />the best available data source (shown in Figure 2). Monthly diversions for Berthoud Pass <br />Ditch are presented in Table 2. The preferred set of data identified for Berthoud Pass <br />Ditch was the continuously monitored data for Station 09021500.
