On #1 pond, Trout are piled up at the head of the pond, where a tiny amount of water flows into it from a culvert that extends from the stream between #2 and #3.
For years, we've stocked trout in the lake and ponds on the golf course. As our weather patterns are changing, is this still a smart thing to do or should we be focusing on other species that can better tolerate warmer waters like bass or bluegills etc?
Trout are freshwater fish that are typically found in cool, clear streams and rivers. They are known for their ability to thrive in fast-moving, oxygen-rich waters, making them a popular game fish for anglers. However, can trout survive in a shallow pond? The answer to this question depends on a variety of factors. In Highlands, our summers are becoming more extreme that what we enjoyed in years past. Our temperatures are averaging higher and our rain events are less common but more extreme when they do occur. Highlands used to accumulate 90" of rain each year by small steady amounts, almost daily. Today, we seem to see more drought-like conditions with the occasional storm that brings 3-4" of rain in short period of time.
One of the main concerns when it comes to trout surviving in a shallow pond is the water temperature. Trout are cold-water fish, meaning they thrive in water temperatures between 50 and 60 degrees Fahrenheit. Shallow ponds may not provide the cool temperatures that trout need to survive. If the water temperature in a shallow pond becomes too warm, trout may become stressed and ultimately die. In Highlands, our water temperatures can get well into the 70's by mid-summer, especially now during the drought we are facing. Our ponds are very shallow, with a maximum depth of about four feet. This allows the water to warm even faster.
Another factor to consider is the size and depth of the pond. Shallow ponds may not have enough space or depth for trout to swim and feed properly. Trout are active swimmers and require space to move around and hunt for food. In a shallow pond, trout may become crowded and compete for resources, leading to stress and potentially death.
Additionally, shallow ponds may not provide enough oxygen for trout to survive. Trout are sensitive to changes in water quality, and low oxygen levels can be detrimental to their health. Shallow ponds may have stagnant water or be prone to algae blooms, both of which can reduce oxygen levels and harm trout. Temperature plays a big role in oxygen levels as well. As water temperature increases, dissolved oxygen levels decrease. Trout prefer the fast moving, oxygen rich current, found in rivers and streams.
On the other hand, if a shallow pond is well-maintained and provides the necessary conditions for trout to thrive, it is possible for trout to survive in such an environment. For example, if the pond is spring-fed and maintains a consistent temperature, trout may be able to survive and even reproduce in a shallow pond.
While trout are typically found in fast-moving streams and rivers, they continue to survive in our shallow ponds and Club Lake. However, I think we are at a crossroads where we need to begin thinking about whether or not it's fair to introduce thousands of fish into this environment year after year. Over the past ten years, we've introduced other species into the lake. Specifically, largemouth bass, crappie, large bluegills and others. These species are thriving and create the same amount of enjoyment catching them as trout do. In fact, I would say hooking a 5 lb. bass is even more fun than a 12" rainbow! During the months of July through September, our trout are doing all they can to survive. It may be time to focus our attention and resources on other fish species, better suited for this environment.
