Lakes Maumelle and Winona - Arkansas

Completed
By Lower Mississippi-Gulf Water Science Center July 3, 2017

Short Title: Lakes Maumelle and Winona

Project Chief: William Green

Cooperator: Central Arkansas Water

Project Time Frame: 1989 - present

Lakes Maumelle and Winona are water-supply reservoirs for the Little Rock and North Little Rock metropolitan areas in central Arkansas. In addition to water supply, the reservoirs are used for recreation and fish and wildlife habitat.

As the urban and agricultural development of the basins has increased in the last 20 years, concerns about the sustainability of the quantity and quality of the water supply also have increased. Monitoring changes in the hydrology and water quality of the basin as the land use changes is critical to managing the resource.

A long-term water-quality database is important to accurately assess present water-quality conditions, trends, and sensitivity to change. Hydrologic and water-quality data have been collected on Lakes Maumelle and Winona and their inflows from 1989 to present by USGS in cooperation with Central Arkansas Water (CAW), the utility that owns and operates the two water-supply reservoirs. Water samples are being collected four times annually at several sites in each lake along with vertical profiles for field parameters. Water-quality samples are collected six times annually plus during three storm events at all streamflow-monitoring sites. In addition, automatic samplers are operating at four tributary sites to collect multiple samples during storm runoff events.

Simulated effects of hydrologic, water quality, and land-use changes of the Lake Maumelle watershed, Arkansas, 2004–10

Lake Maumelle, located in central Arkansas northwest of the cities of Little Rock and North Little Rock, is one of two principal drinking-water supplies for the Little Rock, and North Little Rock, Arkansas, metropolitan areas. Lake Maumelle and the Maumelle River (its primary tributary) are more pristine than most other reservoirs and streams in the region with 80 percent of the land area in the e

Analysis of ambient conditions and simulation of hydrodynamics, constituent transport, and water-quality characteristics in Lake Maumelle, Arkansas, 1991-92

Lake Maumelle is the major drinking-water source for the Little Rock metropolitan area in central Arkansas. Urban and agricultural development has increased in the Lake Maumelle Basin and information is needed related to constituent transport and water quality response to changes in constituent loading or hydrologic regime. This report characterizes ambient conditions in Lake Maumelle and its majo

Water-quality assessment of the Frank Lyon, Jr., nursery pond releases into Lake Maumelle, Arkansas, 1991-1996

Releases of the Frank Lyon, Jr., Nursery Pond into Lake Maumelle were monitored during 1991 through 1996 to assess the impact that the releases have on the water quality of Lake Maumelle. Results indicated that the water-quality impact of the nursery pond release into Lake Maumelle is variable, and appears to be related to the volume of the nursery pond at release and the amount of fertilizer appl

Water quality assessment of Maumelle and Winona reservoir systems, central Arkansas, May 1989-October 1992

Water quality of the Maumelle and Winona water supply reservoir systems in central Arkansas, was assessed on the basis of the data collected from May 1989 through October 1992.

Hydrologic data collected in Maumelle and Winona reservoir systems, central Arkansas, May 1989 through October 1992

Physical, chemical, and biological water-quality data were collected and compiled for sites located in the Lakes Maumelle and Winona reservoir systems May 5, 1989, to October 30, 1992. Data were collected in order to establish a comprehensive water-quality data base for the two systems and will be used in water-quality interpretive chemical variables (temperature, pH, specific conductance, dissolv
