California's Yolo Bypass: Evidence that flood control can be compatible with fisheries, wetlands, wildlife, and agriculture
T. Sommer, B. Harrell, M. Nobriga, R. Brown, P.B. Moyle, W. Kimmerer, Laurence E. Schemel
2001, Fisheries (25) 6-16
Unlike conventional flood control systems that frequently isolate rivers from ecologically-essential floodplain habitat, California's Yolo Bypass has been engineered to allow Sacramento Valley floodwaters to inundate a broad floodplain. From a flood control standpoint, the 24,000 ha leveed floodplain has been exceptionally successful based on its ability to convey up...

D.J. Twedt, R.R. Wilson, J. L. Henne-Kerr, R.B. Hamilton
2001, Journal of Wildlife Management (65) 450-460
In the Mississippi Alluvial Valley, flood control has led to a drastic reduction in the area of forest habitat and altered the patchwork of forest cover types. Silvicultural management of the remaining fragmented forests has changed to reflect the altered hydrology of the forests, current economic conditions of the area,...
Flow and habitat effects on juvenile fish abundance in natural and altered flow regimes
Mary C. Freeman, Z.H. Bowen, K.D. Bovee, E.R. Irwin
2001, Ecological Applications (11) 179-190
Conserving biological resources native to large river systems increasingly depends on how flow-regulated segments of these rivers are managed. Improving management will require a better understanding of linkages between river biota and temporal variability of flow and instream habitat. However, few studies have quantified responses of native fish...
