National water summary 1988–89 — Hydrologic events and floods and droughts National water summary 1988–89 — Hydrologic events and floods and droughts
National Water Summary 1988-89 - Hydrologic Events and Floods and Droughts documents the occurrence in the United States, Puerto Rico, and the U.S. Virgin Islands of two types of extreme hydrologic events floods and droughts on the basis of analysis of stream-discharge data. This report details, for the first time, the areal extent of the most notable floods and droughts in each State...

The status of the Red Hills salamander Phaeognathus hubrichti, Alabama, USA, 1976–1988 The status of the Red Hills salamander Phaeognathus hubrichti, Alabama, USA, 1976–1988
A total of 144 sites in the Red Hills Physiographic Province in south-central Alabama, USA, were surveyed in 1988 for burrows of the Red Hills salamander Phaeognathus hubrichti. Of 92 sites surveyed in 1976, no change occurred in the habitat at 54 sites, conditions improved at 19 sites and deteriorated at 18 sites following selective or clear cutting. An additional 14 of 52 sites not...

Stocking of hatchery-reared striped bass in the Patuxent River, Maryland: survival, relative abundance, and cost-effectiveness Stocking of hatchery-reared striped bass in the Patuxent River, Maryland: survival, relative abundance, and cost-effectiveness
Hatchery-reared fingerlings of striped bass Morone saxatilis were tagged, stocked, and recovered in the Patuxent River, Maryland, to estimate their survival and abundance relative to wild young of the year and to compare the costs and benefits of stocking phase-I (35–50 mm, total length) and phase-II (150–200 mm) fish. About 100,000 phase-I fingerlings were tagged and released each year...

Floods in the Nishnabotna River basin, Iowa Floods in the Nishnabotna River basin, Iowa
Flood-elevation profiles and flood-peak discharges for floods during 1972, 1982, and 1987 in the Nishnabotna River basin are given in this report. The profiles are for the 1972 flood on the West and East Nishnabotna Rivers, the 1982 flood on Indian Creek, and the 1987 flood on the lower West Nishnabotna River. A flood history describes rainfall conditions and reported damages for floods...

Changes in chloride concentration in water from municipal wells that tap aquifers in rocks of Cambrian and Ordovician age in northeastern Illinois, 1915–84 Changes in chloride concentration in water from municipal wells that tap aquifers in rocks of Cambrian and Ordovician age in northeastern Illinois, 1915–84
During the past few decades, several municipalities in northeastern Illinois have noted increases in the salinity of water from wells that tap aquifers in rocks of Cambrian and Ordovician age. The municipalities have discontinued the use of, or sealed-off sections of, those wells. The aquifers involved include the Ancell, the Ironton-Galesville, and the Elmhurst-Mt. Simon. To define the...

Preliminary assessment of the effects of selenium in agricultural drainage on fish in the San Joaquin Valley Preliminary assessment of the effects of selenium in agricultural drainage on fish in the San Joaquin Valley
Concentrations of total selenium were measured in whole-body samples of seven fishes from the Sacramento and San Joaquin River systems and the San Francisco Bay complex. Concentrations of selenium (up to 11 µg/g dry weight in whole-body composite samples) were highest in fish from canals and sloughs in the Grassland Water District (Grasslands) that received large inflows of subsurface...

Distribution patterns of individually identifiable West Indian manatees (Trichechus manatus) in Florida Distribution patterns of individually identifiable West Indian manatees (Trichechus manatus) in Florida
Photographs of distinctively scarred manatees (Trichechus manatus) were taken at aggregation sites throughout Florida and assembled into a catalog for identifying individuals. Resightings of known manatees in different years or at different locations enabled us to document site fidelity and long-distance movements. Of the 891 individuals included in the catalog as of August 1986, 470 (53...
