The location of the South Branch of St. Vrain C.:eek is shown on a map, Exhibit 3. There are no records of discharges into the "~ South Branch from St. Vrain Creek. The present South Branch channel through i the Weng farm meanders in a generally northwest to southeast direction a ~_ distance of about 2,320 feet (Exhibit 2). The fall from the west boundary entrance point to the south boundary exit point is about 11 feet. Tlxe ~` ~ average slope of South Branch through the Weng farm is about 0.47 percent. The roughness coefficient ("n" in Manning equation) is estimated to be 0.025. Measurements at critical points indicate a minimum cross-sectional area of about 37 square feet, with bank-full flow.

Seven ground water observations pipes were installed at strategic points on the John Weng farm in September 1969. The locacio~ of each observation pipe is shown on Exhibit 2. Depths to water below ground surface on the Weng farm varies with topography and ranged from 1.3 feet to 4.0 feet in September 1969.
