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)

Habitat Evaluation Procedure Report For Proposed Kaniksu Unit Of The Little Pend Oreille National Wildlife Refuge
Little Pend Oreille National Wildlife Refuge is proposing to acquire a 706-acre property located in Stevens County, Washington. The new acquisition would be called the Kaniksu Unit. A habitat evaluation was conducted on the property using the Habitat Evaluation Procedures (HEP) methodology (U.S. Fish and Wildlife Service 1980). Evaluation species were black-capped chickadee, mallard, ruffed grouse and white-tailed deer. Life requisites evaluated were food and reproduction for black-capped chickadee, food, cover, and reproduction for mallard, available winter browse for white-tailed deer and fall-to-spring cover for ruffed grouse
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.

Integrated Status and Effectiveness Monitoring Program - Entiat River Rotary Screw Traps,Snorkel Surveys, and Steelhead Redd Surveys, 2008.
The USFWS Mid-Columbia River Fishery Resource Office (MCRFRO) operated two rotary screw traps on the Entiat River as part of the Integrated Status and Effectiveness Monitoring Program from March through November of 2008. Along with the smolt traps, juvenile emigrants were also captured at remote locations throughout the Entiat watershed and its major tributary, the Mad River. A total of 16,782 wild salmonids were PIT tagged during the study period. Of this, 3,961(23.6%) were wild Oncorhynchus mykiss, 6,987 (41.6%) were wild spring run O. tshawytscha, and 5,591 (33.3%) were identified as wild O. tshawytscha of unknown run. Rotary screw trap efficiencies averaged 40.3% at the upper (Rkm 11.0) trap and 7.8% for the lower (Rkm 2.0) trap. These efficiencies were pooled for emigrant O. tshawytscha and O. mykiss. The MCRFRO conducted effectiveness monitoring snorkel surveys at 24 sites during the winter period and 30 sites during the summer and fall periods of 2008 as part of the Integrated Status and Effectiveness Monitoring Program in the Entiat River. The 2008 steelhead spawning grounds surveys were conducted weekly in the main Entiat River from rkm 1.1 to 44.2. A total of 222 steelhead redds were identified over the period from February 28 to June 16 2008 with April being the peak spawning month. Approximately 80% of the steelhead redds were located downstream of the rkm 26
