BOISE, Idaho (CBS2) — Idaho anglers may see fewer fishing opportunities this summer as drought and rising temperatures strain fisheries across the state, according to Idaho Fish and Game.
Officials say low water levels and warming temperatures could lead to fish die-offs, reservoir closures, salvage fishing opportunities, and possible fish relocations where conditions allow. However, the agency said moving fish is not always practical or beneficial, and decisions are based on scientific assessments.
Managers weigh factors such as fish survival during transport, available habitat, staffing, and whether relocation would improve fishing elsewhere. In some cases, allowing anglers to harvest fish under salvage regulations may be the best option.
Fish and Game noted that many reservoirs primarily serve irrigation needs, which can limit water availability for fisheries during drought. While trout populations can often be restored relatively quickly through stocking once conditions improve, warmwater species such as bass and panfish may take several years to recover.
Sturgeon are especially vulnerable to low, warm water. The agency temporarily closed sturgeon fishing in parts of the Snake River last year following reports of fish deaths and said similar closures may be necessary again.
Rivers and trout are generally more resilient because fish can move to cooler water, but prolonged summer stress can still lead to delayed mortality. Fish and Game said reduced trout activity during hot weather often lowers fishing pressure naturally, making season changes unnecessary in most cases.
