Imperial Ponds Native Fish Monitoring
Status: Ongoing
A series of ponds were constructed adjacent to the river on the U.S. Fish and Wildlife Service Imperial National Wildlife Refuge (INWR). These ponds were built to provide off-channel habitat free of nonnative fishes for the survival and reproduction of bonytail and razorback sucker. Marsh & Associates was contracted to conduct a three-year project to determine the suitability of these ponds for native fishes
