Abstract

Arkansas&rsquo Expanded Relational Water-Use Program

Author(s): Holland, T.

The Arkansas Water-Use Program is a cooperative effort between the Arkansas Natural Resources Commission (ANRC) and the U.S. Geological Survey (USGS). Site-specific data for several water-use categories are reported annually by water users and are electronically stored. Water users that withdraw 1 acre-foot or more of surface water per year or operate wells with the capability of pumping 50,000 gallons of ground water per day or more must report their withdrawals. Site-specific water-use data for irrigation, livestock, duck hunting clubs, public supply, commercial, industrial, mining, and power generation are stored in the Arkansas Water-Use database developed and maintained by the USGS Arkansas Water Science Center (AR WSC). Data for the irrigation, livestock, aquaculture, and duck hunting club categories are reported through the Conservation District offices in selected counties. Users report data for about 54,000 agricultural measurement points through the County Conservation District offices via a secure internet Web page that is the entry point into the Arkansas Water-Use Data System. Water-use data for the other categories are reported directly to the Arkansas Natural Resource Commission on paper registration forms generated by AR WSC staff as output from the data base management system. These forms are mailed out by ANRC staff to about 1,200 additional water users that do not report their water use via the Web. The completed registration forms are returned to U.S. Geological Survey for entry in to the Arkansas Water-Use Data Base System. The amounts of water withdrawn, sources of water, how the water was used, and how much water was returned are available to water-resources managers and policy makers through retrievals from the Arkansas Water-Use Data Base System.

Expansion of the Arkansas Water-Use System began 3 years ago for multiple reasons. ANRC needed a viable way to store and retrieve water-well construction information that Arkansas law requires be reported to the Arkansas Water-Well Commission (a component of ANRC) and, the understanding of ground-water use would be enhanced with a relational link to well construction information; and, a better understanding of hydrogeologic structure would further compliment ground-water use understanding and provide enhanced information concerning water-bearing zones contributing to wells. Consequently, tables have been added to the system as a repository for water-well construction data and a Well Log Archive. Staff at the ANRC enters data into the water-well construction tables. Construction data for approximately 57,000 wells reside in the database at this time. Well log archiving is a continuing effort, in the ANRC/USGS cooperative program, to archive and interpret borehole geophysical logs. As a part of our continuing cooperative program, well logs for a few Arkansas counties are scanned and geo-referenced each year - 12 counties have been completed to date. The tops of aquifers and confining units are interpreted from these logs for the purpose of creating a digital framework of the subsurface. This framework of hydrogeologic units is used in conjunction with a reported water-use location to determine/verify contributing aquifers. This is a "visual" process, using an interactive mapping application.

Workshops

Responsible Site Design: Implementing Innovative Stormwater Management Strategies

The primary goal of the workshop is to create a dynamic learning experience that examines the role of stormwater management in the built environment. The workshop will focus on integrating ecologically sound water management approaches into site design. After the workshop, attendees will be familiar with the following concepts and technical issues:

  • Knowledge of the stormwater treatment chain
  • Knowledge of the impact of land use codes on stormwater management
  • Application of a design process that mitigates the effects of stormwater on-site
  • Knowledge of the relationship between land use codes and design for innovative stormwater management
