Specifically, the time <br />frame for the test flow was selected to reduce impacts on river resources, by <br />conducting the test flow: 1) prior to native fish (especially humpback chub) <br />spawning, or larval dispersal; 2) after the peak of rainbow trout spawning at <br />Lees Ferry; 3) several weeks after the peak concentrations of wintering bald <br />eagle and waterfowl 4) prior to the Neotropical bird and waterfowl breeding <br />seasons; S) during a month in which high flows occurred in the pre-dam era; 6) <br />prior to the peak release of non-native saltcedar (Tamarix ramosissima) seeds <br />in late April and May, to allow riparian soils time to desiccate after the <br />test flow, thereby reducing saltcedar germination; and 7) prior to the <br />recreational river rafting season. <br /> <br />restored <br /> <br />3' <br />
