How To Read Fish Plant Graphs

To interpret fish plant graphs effectively, consider the following key elements:

  1. Blue Vertical Bars and Numbers:
    • Representation: The blue vertical bars on the graph represent individual fish plants.
    • Weight Measurement: The associated numbers indicate the total weight of the plants in pounds (lbs.) that occurred during a specific week.
    • Significance: Monitoring these bars helps identify weeks with higher planting activity, aiding anglers in selecting optimal times for fishing near recent plantings.
  2. Orange Trend Line:
    • Purpose: The orange trend line represents the moving average of all fish plant activities at the specified location.
    • Indicator of Activity: A rising trend line suggests a consistent increase in planting activity over the designated period. This indicates the potential for more catch opportunities and signifies a growing fish population over the weeks.
  3. Interpreting the Moving Average:
    • Upward Trend: A rising moving average implies an upward trajectory in planting activity, indicating an increasing number of fish being introduced into the area. This suggests a positive outlook for anglers, as it implies a larger and potentially more accessible fish population.
    • Downward Trend (Not Specified): The description does not provide information on the interpretation of a decreasing trend in the moving average. It might be beneficial to include information on what a decreasing trend could signify in terms of fishing prospects.
  4. No Data Present:
    • Possible Explanations: If no data is visible on the graph, it may indicate that the location had no fish plants in the last three months. Alternatively, the absence of data could be due to non-disclosure of fish plants for that location.
    • Natural Population: Some fishing areas in California rely on the natural growth of fish populations, and graphs may not show plants if this is the case.
  5. Graph Disclaimer:
    • Data Source: The graphs reflect a combination of publicly disclosed data and estimates. Some locations may disclose fish plants without specifying exact amounts.
    • Not Universal: Not all fishing areas have fish plants, and the natural growth of fish populations plays a significant role in many California fishing locations.

Understanding these elements will empower anglers to make informed decisions about when and where to fish based on historical fish plant data.

Note: If no data is present in the graph above, this location may not have had any plants the last 3 months, or may not have publicly disclosed plants. Graphs reflect both publicly disclosed data and estimates, as some locations disclose plants, but not exact amount.

Types of Fish You Can Expect to Catch Here

  1. Rainbow Trout: Abundant throughout the lake, rainbow trout take center stage in Lewiston. Their large sizes, exceeding 10 pounds, make them a thrilling catch, especially in the spring and fall.
  2. Brown Trout: While less common than rainbow trout, brown trout in Lewiston Lake present a formidable challenge for anglers. Target them using live bait like minnows or nightcrawlers.
  3. Brook Trout: Smaller than their counterparts, brook trout inhabit the colder, higher-elevation streams feeding into the lake. Anglers can use small spinners or flies to entice these elusive fish.
  4. Kokanee Salmon: Found in the deeper waters of Lewiston Lake, kokanee salmon offer a unique fishing experience. Use downriggers and spoons to enhance your chances of a rewarding catch during spring and summer.

Exploring the Historical Significance

Lewiston Lake, situated at 1,900 feet, spans nine miles in length with 750 acres of pristine waters and 15 miles of shoreline. Despite its natural beauty, fishing quality can fluctuate, with the Trinity Dam powerhouse playing a pivotal role in angling success. When the powerhouse is active, trout fishing becomes exceptional, particularly from Lakeview Terrace upstream. Anglers can capitalize on the powerhouse’s influence by anchoring in the current and using night crawlers or opting for yellow Power Bait when it’s inactive. Fly-fishing specialists can explore tules along the western shoreline, while non-fly fishers can experiment with the fly-and-bubble technique.

The Department of Fish and Game contributes to Lewiston’s vibrant fish population by stocking rainbow trout, brook trout, and brown trout. A pen-rearing project adds to the lake’s allure, showcasing a conservation-conscious approach that can serve as an example for other lakes across the state. Despite being overshadowed by Trinity Lake, Lewiston Lake offers quality camping, fishing, boating, and hiking opportunities. With a 10 mph speed limit, the lake maintains a quiet and calm ambiance, ideal for anglers using canoes and small aluminum boats.

Top 5 Tips for First-Time Anglers

  • Power of the Powerhouse: Leverage the influence of the Trinity Dam powerhouse. When active, anchor in the current with night crawlers; when inactive, use yellow Power Bait near the point where the current flattens into the lake.
  • Fly-Fishing Exploration: Consider fly-fishing, especially near tules along the western shoreline. Wade out during the evening rise for an immersive angling experience.
  • Trout Trolling Techniques: Utilize traditional trolling methods as a last resort. Trail half a night crawler behind flashers to entice trout when other methods falter.
  • Pen-Rearing Project Insights: Stay informed about the pen-rearing project at Lewiston, where trout are grown until they reach three pounds. This knowledge can enhance your understanding of the lake’s diverse fish population.
  • Quiet Pursuits: Embrace the tranquility of Lewiston Lake with quiet water activities. The 10 mph speed limit ensures a calm atmosphere, perfect for anglers using canoes and small aluminum boats.

Top 5 Strategies and Tactics for Optimal Fishing

  1. Strategic Seasonal Approach: Plan your fishing expeditions in alignment with the seasons. Spring and fall are prime times for a successful catch, with different species flourishing in varying parts of the lake.
  2. Power of Anchoring: Capitalize on the powerhouse’s activity by anchoring strategically. Adjust your location based on whether the powerhouse is running or not, optimizing your chances of encountering trout.
  3. Fly-and-Bubble Technique: Non-fly fishers can experiment with the fly-and-bubble technique, which involves using a fly behind a bubble. This method can attract bites, adding versatility to your angling repertoire.
  4. Trolling Mastery: When other methods fail, master the art of trolling. Trail half a night crawler behind flashers for a reliable fallback when more specialized techniques prove challenging.
  5. Adapt to Changing Depths: Recognize the lake’s average depth of 20 feet. During the warmer summer months, when fish go deeper, adapt your strategies accordingly to ensure a productive angling experience.
