“…The objectives of NAWDEX are to define available types of water data, where and how the data are stored, and how they may be obtained. An overview of the history and structure of NAWDEX has been published by Edwards (1976 codes to provide for the inclusion of ground-water data in STORET (Hampton, 1976, p. 54-56). As of 1977, STORET has no efficient way to store lithologic or site-inventory data which are not logically time-dependent.…”

A program was designed for the systematic monitoring of groundwater quality in Nevada. Basic hydrologic and water-quality principles are discussed in the formulation of a rational approach to developing a statewide monitoring program. A review of groundwater monitoring efforts in Nevada through 1977 indicates that few requirements for an effective statewide program are being met. A suggested program has been developed that consists of five major elements: (1) A Background-Quality Network to assess the existing water quality in Nevada aquifers, (2) a Contamination Source Inventory of known or potential threats to groundwater quality, (3) Surveillance Networks to monitor groundwater quality in selected hydrographic areas, (4) Intensive Surveys of individual instances of known or potential groundwater contamination, and (5) GroundWater Data File to manage data generated by the other monitoring elements. Two indices have been developed to help assign rational priorities for monitoring ground water in the 255 hydrographic areas of Nevada: (1) A Hydrographic-Area Priority Index for surveillance monitoring, and (2) A Development-Potential Index for background monitoring of areas with little or no current development. Requirements for efficient management of data from groundwater monitoring are discussed and the three major systems containing Nevada groundwater data are reviewed. More than 11,000 chemical analyses of ground water have been acquired from existing systems and incorporated into a prototype data base.

“…The U.S. Geological Survey's Office of Water Data Coordination has been designated as the coordinator of water-data acquisition activities by more than 30 Federal agencies. The exchange of water data is facilitated by the National Water Data Exchange (NAWDEX),a National confederation of water-oriented organizations working together to improve access to water data (Edwards, 1977). The Kansas District Office, one of 63 NAWDEX assistance centers, annual-ly processes more than 300 requests for sources of water information.…”

The U.S. Geological Survey is the principal Federal agency cooperating with State agencies in the collection of hydrologic data needed for the planning, development, use, and management of the water resources in Kansas.Hydrologic-data collection by the U.S. Geological Survey in Kansas began in 1895.The fiscal-year 1983 water-data program, operated in cooperation with several Federal, State, and local agencies, included 278 stations for collection of river, lake, and reservoir data; 1,940 wells for collection of groundwater data; and 58 sampling stations and 215 wells wells for collection of water-quality data.This report provides a detailed description of the waterdata program, including coordination and funding* data-collection activities,quality-assurance plans, availability of data, network design, and future needs for water data.

All waterquality analyses and stage-discharge records are published annually and are also accessible through NAWDEX (Edwards, 1977 were set aside primarily for computation of the water budget and transport of nutrients and detritus.

Nutrient and detritus transport in the Apalachicola River, Florida

The Landsat image on the cover shows the extent of the flood plain in the Apalachicola River Basin, Florida. The dark color of the flood plain is caused by the low reflectance from flood waters. The 200-m wide river is barely visible in the center of the 3.2 to 8.0-kmwide flood plain. The Apalachicola River flows from Lake Seminole (at the top), 171 km south, to Apalachicola Bay (near the bottom of the scene). The numerous white squares near the top of the scene are agricultural fields ir Florida and Alabama. The large red area east of the river is pine forest (Apalachicola National Forest). The faint brown color on the birdsfoot delta at the river mouth is marsh. The light blue colors near the beaches at the bottom of the scene are a combination of shallow areas and areas with high suspended sediments caused by ocean currents.
