Constituent Loads And Trends In The Upper Illinois River Watershed And Upper White River Basin, Erin E. Scott, Zach P. Simpson, Brian E. Haggard Jan 2016

Constituent Loads And Trends In The Upper Illinois River Watershed And Upper White River Basin, Erin E. Scott, Zach P. Simpson, Brian E. Haggard

Technical Reports

Water chemistry can greatly influence the quality of surface waters and affect the ability for streams and rivers to meet their designated use(s). In Arkansas, many streams and rivers were placed on the 2008 303(d) list of impaired water bodies due to excess levels of nutrients, chlorides, sulfates, and sediments (ADEQ, 2008). These constituents continue to be listed as the potential cause for water‐quality impairments through the most recent draft 303(d) list (ADEQ, 2014). The Arkansas Non‐Point Source (NPS) Management Program wants to reduce poll‐ utant loading from the landscape and improve water quality, where funding for projects is targeted …

This project focuses on the Upper Illinois River Watershed (UIRW; HUC 11110103), which is within the Boston Mountains and Ozark Highlands ecoregions in northwest Arkansas. Headwaters of the Illinois River originate near Hogeye, Arkansas and flow north through Savoy, then west into Oklahoma near Watts. The UIRW drains an area of 1952 km2 , of which 50.3% is pasture and grassland, 35.9% is forest, 8.8% is urban and suburban, 4.3% is transitional and 0.3% is water (Arkansaswater.org, 2015). Land use throughout the watershed is also changing, with increases in residential, commercial and industrial development. The IRW has been designated a …


Regulatory Drivers For The Upper Illinois River And Other Regional Watersheds, Ray Weida Jun 2010

Regulatory Drivers For The Upper Illinois River And Other Regional Watersheds, Ray Weida

Technical Reports

Environmental regulations are put in place to protect the air, water and land from threat of pollution. Regulatory programs establish pollution limits, determine compliance, and enforce environmental laws and regulations for waterbodies within the watershed based on the designated uses for the individual waterbody. These established regulations make sure that the state’s mandatory standards for clean water and the minimum federal standards are being achieved. Environmental regulations are established on both the federal and state levels. On the federal level, Congress has authorized the U.S. Environmental Protection Agency and other governmental agencies to create and enforce regulations. The EPA delegates …


Final Report To The Illinois River Watershed Partnership: Recommended Watershed Based Strategy For The Upper Illinois River Watershed, Northwest Arkansas, B.E. Haggard, Andrew Sharpley, Leslie Massey, Katie Teague Jun 2010

Final Report To The Illinois River Watershed Partnership: Recommended Watershed Based Strategy For The Upper Illinois River Watershed, Northwest Arkansas, B.E. Haggard, Andrew Sharpley, Leslie Massey, Katie Teague

Technical Reports

This publication serves as the final report to the Illinois River Watershed Partnership (IRWP) regarding the project entitled “Development of the Watershed Management Plan for the Upper Illinois River”. This document was intended to provide this stakeholder based organization guidance in the development of a watershed management plan for the Illinois River drainage area (i.e., the Upper Illinois River Watershed, UIRW) in Arkansas. This document represents the final report from the Arkansas Water Resources Center (AWRC) and affiliated project investigators, and the IRWP may alter this document before the final submission of its watershed management plan to the Arkansas Natural …


A Vision For The Upper Illinois River Watershed, Kent Thornton Jun 2010

A Vision For The Upper Illinois River Watershed, Kent Thornton

Technical Reports

The Upper Illinois River Watershed is a special place where the threads of private, public and non‐profit partnerships are woven into the regional fabric of economic vitality; environmental stability, and social responsibility. Through its cultural heritage, the legacy of land stewardship, integrated with respect for personal property rights, continues. Natural resources are restored and sustained within a healthy mosaic of fields, forests, farms, woodlands, wetland prairies, pastures, cities, and naturally flowing streams. It is an incubator for green energy, entrepreneurial, educational and environmental initiatives.


Illinois River Volunteer Monitoring, L.B. Massey, B.E. Haggard Jul 2009

Illinois River Volunteer Monitoring, L.B. Massey, B.E. Haggard

Technical Reports

Understanding how water quality conditions change along a land use gradient and over time is important for sustainable watershed management. Therefore, a volunteer monitoring program was created to measure water chemistry at 37 established sites within the Upper Illinois River Watershed and to evaluate changes in water chemistry over the past 15 years. The Illinois River Watershed Partnership (IRWP), a non‐profit organization subcontracted with the Arkansas Water Resources Center at the University of Arkansas, to manage the volunteer monitoring project, train volunteers to collect samples following EPA approved methods, and to analyze the collected samples. The AWRC trained 27 volunteers …
