Anglers and recreationists looking forward to summer are becoming increasingly aware they may also be looking into another season of severe drought. Anglers can do a lot to reduce the stress fish feel as a result of low stream flow, higher water temperatures and competition for space and food. Low water conditions in spring and fall can cause spawning failures and loss of young fish to predators. Also, fish will "group up" to take advantage of pools where the water is deeper and cooler -- making them more vulnerable to anglers and predators. If conditions worsen, fish are lost to stress from the higher water temperature, lower oxygen levels, and reduced resistance to disease. These threats can impact adult trout numbers in future years. To help preserve a threatened fishery anglers can:
