Rainwater Basin Wetland Management District Bird List
The Rainwater Basin of south central Nebraska has attracted millions of migratory birds each spring for generations. During migration, millions of snow geese, Canada geese, white-fronted geese, ducks, and 1/2-million sandhill cranes use the Rainwater Basin and the adjacent Platte River. The shallow wetland basins and surrounding croplands of the area provide the birds with critical resting and feeding sites during their migration north. The Waterfowl Production Areas (WPAs) of the Rainwater Basin Wetland Management District (WMD) are managed as grassland-playa lake ecosystems. The Rainwater Basin WMO staff currently manages 59 WPAs in the Rainwater Basin. Most of the WPAs must undergo extensive restoration to provide quality habitat for the millions of migrating birds. To restore wetlands, WMD staff employ a variety of management techniques such as pumping groundwater, prescribed burning, grazing, filling in pits, removing trees, and clearing non-native plants. These lands. once used for agricultural purposes, are now reseeded to recover the native plant communities. The species listed in this leaflet have all been observed in the WPAs. All species names are in accordance with the A.O.U. Check-list of North American Birds 7th edition, 1998. For clarity, some of the former names are shown in parentheses
Evaluation of the Effects of Stage Fluctuations on Overwinter Survial and Movement of Young Colorado Pikeminnow in the Green River, Utah, 1999-2002
Each component of the Flaming Gorge Winter study had specific objectives to address oncerning the effects of winter operations of Flaming Gorge Dam on the survival, distribution, and ursery habitats of age-O Colorado pileeminnow. n Table I, study objectives for each project are resented and the reader is directed to the relevant draft report. The Colorado River Fish Project-Vernal, tah, was responsible for conducting field investigations (i.e., population estimates, winter fish sampling, nd monitoring stage fluctuations) in the alluvial reach occupied by age-O Colorado pileeminnow. olorado State University was responsible for characterizing movement rates under simulated winter onditions; and developing and eValuating a bioenergetics model for age-O Colorado pileeminnow

Fish Passage Engineering Design Criteria
Anthropogenic activities in rivers may introduce undue hazards to many aquatic organisms and contribute to overall habitat fragmentation. Fragmentation may negatively alter the structure and diversity of both diadromous and resident fish populations. These adverse impacts can be mitigated through dam removal, and a variety of technical and nature-like fish passage and protection technologies. Fish passage and protection (hereafter simply “fish passage”) requires the integration of numerous scientific and engineering disciplines including fish behavior, ichthyomechanics, hydraulics, hydrology, geomorphology, and hydropower. This document is intended to: 1) establish Engineering’s “baseline” design criteria for fishways, dam removals, road crossings and other fish passage related technologies; 2) serve as a resource for training in these disciplines; and 3) support the implementation of the Service’s statutory authorities related to the conservation and protection of aquatic resources (e.g., Section 18 of the Federal Power Act, Endangered Species Act, Fish and Wildlife Coordination Act, and the Anadromous Fish Conservation Act)
Proceedings of the Twenty-second Annual Symposium on Sea Turtle Biology and Conservation, 4-7 April, 2002, Miami, Florida
The 22nd Annual Symposium on Sea Turtle Biology and Conservation was held April 4-7, 2002 in Miami, Florida and hosted by the U.S. Fish and Wildlife Service. The 22nd symposium was the most globally diverse ever with 839 individuals from 73 countries attending the symposium and associated regional meetings. One third of the attendees were from outside the United States.
This diverse attendance was made possible in large part because of substantial donations from The Packard Foundation, National Fish and Wildlife Foundation, National Marine Fisheries Service, U.S. Fish and Wildlife Service, Convention on Migratory Species, Oceanic Research Foundation, and International Sea Turtle Society which supported travel grants for 170 international travelers.

The 'Baird Memorial"
In mid 1903, during the annual meeting of the American Fisheries Society, AFS members, U.S. Fish Commission (USFC) staff, and other interested persons gathered at Woods Hole, Mass., to dedicate a permanent memorial to Spencer F. Baird, founder of the U.S. Fish Commission. President of the AFS that year was the USFC Commissioner George M. Bowers. Speakers were Chicago attorney E. W. Blatchford; W. K. Brooks, a professor at Johns Hopkins University, Baltimore, Md., who had conducted research at the Commission's Beaufort Laboratory; and, very briefly, the noted fish culturists Frank N. Clark of Michigan and Livingston Stone of Vermont. The following record of the dedication ceremony appeared as a twopart article in The Fishing Gazette, 22 and 29 August 1903
