Communities that use fill-and-draw waste-water treatment lagoons or waste-stabilization ponds are required to discharge during the spring and fall of the year at a rate that does not exceed the assimilative capacity of the receiving stream. The 10-year low mean monthly discharge (MMQ10) for October, November, April, and May for the receiving stream has been used to establish the discharge rate for

A broad-perspective analysis of the ground-water resources and present and possible future water development and management in the Souris-Red-Rainy Region is presented. The region includes the basins of the Souris River within Montana and North Dakota; the Red River of the North in South Dakota, North Dakota, and Minnesota; and the Rainy River within Minnesota. The region includes 59,645 square mi

Hydrologic phenomena are dynamic, so their understanding and prediction are difficult and challenging. Many are cyclic, ranging from diurnal, seasonal, and annual cycles to climatic fluctuations of many hundreds or thousands of years. Predicting the magnitude and recurrence intervals of long-term fluctuations of these phenomena is a primary concern of hydrologists. The best data upon which to bas

Flowing wells yielding fresh water occur in both the glacial drift and the bedrock in Michigan. Most known flowing wells are in the Lower Peninsula because the greater population in that part of the State has led to more frequent drilling. A comparison of flowing-well areas in 1900 with those in 1970 shows a probable decline in head in the glacial drift and the Marshall and Saginaw bedrock formati

Intensified land development on the Anoka sand plain necessitates a better understanding of the hydrogeology of the surficial outwash deposits of the area. The Anoka sand-plain aquifer consists of outwash attributable to two different ice lobes. Predominant grain size of the upper outwash decreases and sorting coefficient increases from west to east. Till or lake deposits underlie most of the surf

An investigation of flood flows from small drainage basins in Minnesota was initiated to aid in the design of bridges, culverts and other highway drainage structures. The program provides peak flow data on streams having drainage areas generally less than 50 square miles, placing particular emphasis on those less than 10 square miles. Basin parameters being investigated are drainage area, length o

The purpose of this report is to make available the records of water levels in principal aquifers of the State through 1976 and to compile related data, such as records of ground-water pumpage. Also included in the report are data on municipal, public, and industrial water-supply facilities. Records of water levels in areas of heavy pumpage and in areas where changes are principally due to natural

Water resources data for the 1976 water year for Michigan consist of records of stage, discharge, and water quality of streams; stage, contents, and water quality of lakes and reservoirs; and water levels in wells. This report contains discharge records for 194 gaging stations; stage and contents for 5 lakes and reservoirs; water quality for 75 continuous record stations, 28 partial-record station

Water resources data for the 1975 water year for Michigan consist of records stage, discharge, and water quality of streams; stage, contents, and water qualit of lakes and reservoirs; and water levels and water quality in wells and springs. This report contains discharge records for 207 gaging stations; stage only record for 1 gaging station; stage and contents for 5 lakes and reservoirs; water qu
