Exploring the Hidden World of Trout: Insights from High-Use and Tailwater Fishing

The True Nature of Trout

Trout, the elusive and majestic creatures of rivers and streams, possess intriguing behaviors that vary depending on their habitat. When fishing in a well-known river venue for trout, you may be surprised to discover how many of these fish are simply waiting for you to leave. These trout have become acclimated to the presence of people and have learned that if they hunker down and refrain from feeding, the perceived threat will eventually dissipate.

However, the scenario drastically changes when fly fishing in less popular river venues. Wild trout, which seldom encounter people, are naturally more cautious and fearful of human presence. As you approach the water, these trout scatter like mice, creating zigzag patterns as they run over each other in an attempt to escape. Their behavior is a testament to their wariness of potential danger.

This stark contrast in behavior can be attributed to various factors, not solely the fish becoming accustomed to people. One significant factor may be the limited extent of heavily fished venues, such as tailwaters below dams. In these shortened runs, trout may not have anywhere to flee. Habitats may only span a mile or two, and the fish have learned that both upstream and downstream are occupied by humans. With this knowledge, they have adapted by merely hanging out and refraining from feeding until the angler moves on. These trout are educated in the art of survival and have developed a tolerance for human presence.

Tailwaters: A Trout Haven

In South Park, Colorado, a high-altitude basin nestled between mountain ranges, multiple gold medal waters exist. Two of these areas are tailwater systems, where the water beneath a dam spillway consistently maintains a cool temperature and ample oxygen levels, making it an ideal habitat for trout.

Unlike water that spills over the top of a dam, which is susceptible to temperature variations throughout the seasons, the water released from the bottom of a dam remains unfrozen. Consequently, tailwaters provide year-round fishable conditions for trout. This constant flow of water from the reservoir’s depths ensures that aquatic insects, which constitute a trout’s primary diet, are consistently engaged in their life-cycles, reproducing and generating more pupae or nymphs.

Additionally, state biologists often introduce mysis shrimp and scuds, two types of crustaceans, to tailwaters. These tiny aquatic animals serve as a super-enriched source of nutrition for trout, allowing them to grow into substantial sizes. The spillway area, with its cool temperature and elevated oxygen levels from the flowing water, becomes a paradise for these crustaceans and abundant pupae and nymphs. It is this abundance of food sources that contributes to the remarkable size of trout found in tailwaters.

Cracking the Code: Out-Waiting the Trout

Trout possess keen observational skills and remarkable memories, recalling both positive and negative experiences. This knowledge is invaluable when fishing in high-use areas like tailwaters. Here, trout are more likely to remain in place, waiting for anglers to leave, as they have limited escape options due to their restricted habitat. As an angler, your job is to out-wait them by exercising patience and being conservative in your movements on the water. Have faith in their presence and their eventual return to feeding.

Understanding that trout are nearby provides a significant advantage. Take the time to analyze your surroundings and devise a plan. Consider utilizing techniques like “high-sticking,” a method that involves holding the rod high to keep the colored part of the line off the water. By not casting very far, you can present the fly to pockets of water near you and even include the water downstream. This unorthodox approach offers greater control over the drift and allows you to skim the top of riffles more effectively.

So, the next time you find yourself fishing in a famous venue known for its fishing pressure, rest assured that the trout are present. Embrace the challenge, exercise patience, and utilize strategic techniques. By doing so, you will unlock the hidden world of trout and witness their resumption of feeding behaviors.
