- Characteristics of Urban Runoff from Grange Hall Creek at Northglenn, Adams County, Colorado
- Purpose: The purpose of the study was to (1) determine quantity and quality of urban runoff from the upper Grange Hall Creek drainage basin in Northglenn; (2) identify constituents exceeding water-quality standards for agricultural waters; (3) compare differences in quality between dry-weather flow, snowmelt runoff and rainfall runoff; (4) determine rainfall-runoff relationships; (5) investigate relationships between constituent concentrations, specific conductance, and streamflow; and (6) suggest, where appropriate, alternatives of urban-runoff management.

- From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."
