Without the access to necessary habitat, fish populations may suffer. Mobility is everything. The service's Arizona Fishery Resources Office is similarly engaged. But a low-head dam that delivered irrigation water also blocked fish movement. The White Mountain Apache Tribe and Arizona Fishery Resources Office redesigned the dam to continue delivering irrigation water.
Flows are now concentrated midstream over a natural bottom that easily passes fish.
But even small structures if not properly placed can have big consequences on fish populations. All Rights Reserved. Terms under which this service is provided to you. Read our privacy guidelines .
