American Heritage Rivers

Description: This report discusses the American Heritage Rivers Initiative, implemented in 1998 by President Bill Clinton. The Initiative designed 14 rivers as "American Heritage Rivers," and declared that each "will receive help over the next five years tapping federal resources to carry out their plans for revitalizing their rivers and riverfronts." This report also discusses the reactions from both supporters and detractors of the initiative, and related legislation and appropriations.

A Method for Estimating Ground-Water Return Flow to the Lower Colorado River in the Yuma Area, Arizona and California

Description: Purpose and scope: The purpose of this study was to develop a method for estimating the amount of subsurface return flow to the Colorado River in the Yuma area. This report presents a method that permits an approximate accounting of ground-water return flow from each side of the Colorado River in Yuma reach. The method presented in this report was developed specifically for application in the Yuma area. The validity of the assumptions inherent in the method was evaluated on the basis of the local hydrologic system. The applicability of the method to other hydrologic systems is not addressed in this report.

Graphical Method for Estimating Occurence and Duration of a Critical Low Flow in the Sacramento River at Freeport, California

Description: Abstract: Sacramento County expected to begin operation of the Sacramento Regional Wastewater Treatment Plant in 1982. The California State Water Resources Control Board has ruled that the plant will not be allowed to release effluent into the Sacramento River when flow in the river is 4,000 cubic feet per second or less. Depending on tide condition, flows less than 4,000 cubic feet per second may occur either once or twice during each 24-hour 50-minute tide cycle when the daily mean flow is less than about 12,000 cubic feet per second. Daily mean flows less than 12,000 cubic feet per second occur about 28 percent of the time. Riverflow at the plant outfall is monitored by an acoustic streamflow measuring system. Regulation of effluent released from the plant will normally be based on real-time flow data computed by the acoustic system. A graphical method for determining the occurrence and duration of flows of 4,000 cubic feet per second and less was developed as a backup system to be used if a temporary failure in the acoustic system occurs.

Identification and Classification of Perennial Streams of Arkansas

Description: From introduction: The primary purpose of this study was to identify perennial streams. The secondary purpose was to classify them by flow. This information can be useful for planning and designing water supplies, analyzing environmental and economic impacts of various projects, water-quality modeling, and the determination of optimum and maintenance flows for a variety of instream uses.

The Wild and Scenic Rivers Act and Federal Water Rights

Description: This report discusses federal authority over water, and federal "reserved" and non-reserved water rights. Based on the language of the act and its legislative history, it appears that the act creates federal water rights. The act does not specify the quantity of the right. The amount of the federal right is likely to vary from river to river depending on the river's flows, the unappropriated flows in the river at the time of designation, and the values for which the river is being protected.
