Beaver River, Lower 
Fishing forecast (March–May): Fishing for brown and rainbow trout improves in the spring as the water warms up and fish get more active. Fish will be skittish during the low water conditions in early spring, so tread lightly. Once flows increase with irrigation releases, fishing gets even better. 

Beaver River, Upper
Fishing forecast (March–May): Fishing conditions change quite a bit throughout the spring as snow melts in Beaver Canyon. Early on, you’re likely to find lots of anchor ice lingering in the shadows, but you can fish pockets of open water in sunny areas. As the anchor ice melts, you'll find more reaches to fish, until full runoff eventually raises the river too high in late spring.
