Download or read book Impact Analysis of the Dempster Highway Culvert on the Physical Environment and Fish Resources of Frog Creek written by R. L. Dryden and published by winnipeg : Department of supply and services. This book was released on 1974 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The impact of improper culvert design and effects on the hydrology and fish biology of Frog Creek, N.W.T. are discussed. Fish migration discharge design, as required by Fisheries and Marine Service for northern highway culverts, is defined. Bank erosion downstream from the culvert caused retreat of the river bank at a rate of 15 cm per day. Siltation of the stream resulting from construction was evident, but apperaed to be insignificant. High water velocities within the culvert blocked the spawning migration of approximately 600 northern pike and appeared to block movements of some broad whitefish. It was estimated that only a small proportion of the total pike population of the Frog Creek drainage was blocked by the culvert. No physiological effects of the culvert delay on ripe pike were evident.

Book excerpt: The success of fish migration through culverts is dependent on the swimming ability of the fish and the hydraulic conditions of the culvert. Properly designed and constructed culverts can minimize the impact on fish passage. Because culverts are typically more economical than bridges, it is appropriate to evaluate when to use culverts and to predict the effects of such culvert installations. During the consideration of alternatives for structures for fish passage, culverts should not be automatically eliminated. This publication has tried to examine the aspects of culvert design and operation relative to the existing information that has been published in previous studies. Ideally, a culvert installation should not change the conditions that existed prior to that installation. This means that the cross-sectional area should not be restricted by the culvert, the slope should not change, and the roughness coefficients should remain the same. Any change in these conditions will result in a velocity change which could alter the sediment transportation capacity of the stream. A truly successful culvert design would include matching the velocities of the fish's swimming zone in the culvert to the swimming capacity of the design fish. Unfortunately, not enough research has been completed to make this an acceptable criterion of culvert design. This approach is preferred because it is easier to reduce the velocities in the swimming zone by increasing the boundary roughness than it is to reduce the mean velocity of the entire culvert. This publication contains some relatively simple guidelines which can reduce the installation problems of culverts in streams containing migrating fish when combined with the expertise of an experience fish biologist, engineer, and hydrologist.

Jessop and published by Department of the Environment, Fisheries and Marine Service, Fisheries Operation Directorate (Central Region), Resource Management Branch, Resource Impact Division. This book was released on 1975 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: In April 1974, the Department of the Environment, Fisheries and Marine Service began the final year of a four year investigation into possible effects of pipeline construction on fish resources of the Mackenzie River valley. The present program includes new and revised findings from the 1974 program. During 1974, emphasis was placed on refining and adding to life history data, particularly migration routes and timing, movements of fry and juveniles and location of overwintering areas. The fish tagging program was intensified on several systems in each study area. A fish fence was constructed in the Trail River to monitor fish movements and to obtain spawning population estimates. Fry traps were used to determine movements of fry and juveniles. A winter survey was conducted to locate significant overwintering areas. Pertinent information on species distribution and migration routes obtained by Fisheries and Marine Service crews based on Richards Island and the Great Bear River also has been incorporated.
