Re: Will I kill 'em?
Fish can survive warmer temps by finding deeper pools, underground springs, or staying downstream of cooler tributaries that enter the larger stream. But if they get hooked and worn out they might die. One of the front range small streams near Denver was closed last summer because flows got very low and temps very high. I swung by one day during August and took a temp and it was over 70. Once things cool down and it reopened I fished it in October and there were plenty of fish there. They survived but needed to be left alone to do so.
