This study responds to a need for baseline physical and chemical data in shallow tropical water bodies. We investigated the degree to which water level fluctuations affected water quality and biota in a shallow tropical pond, Keālia Pond National Wildlife Refuge in Hawaii. We observed strong interactions among climate, water levels, salinity, DO, turbidity, waterbirds, fish, and invertebrates. Seasonal...
Insufficient water supply and poor water quality are major problems in the Klamath Basin of southern Oregon and northern California, USA. Various land-management practices and competing demands for water in much of the basin have led to degraded environmental conditions and poor water quality (excessive nutrients, warn temperatures, high pH, low dissolved oxygen). Of particular interest are the water...
This study presents measurements and modeled estimates of fall water requirements for the seasonal wetlands under moist soil management at Lower Klamath National Wildlife Refuge in northern California, USA. For three representative seasonal wetlands on the refuge, we measured the total volume of water required to fill the units and partitioned this volume into three components: surface water volume,...
