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.

A Glimpse into Quarry Lakes’ History and Unique Features

Quarry Lakes Recreation Area began as an uncertain concept in 1975, with the East Bay Regional Park District and the Alameda County Water District acquiring an old gravel quarry. With a total of about 450 acres, the park district invested $5.8 million in grants and bond money to metamorphose the property into a park. The transformation resulted in three small lakes—Horseshoe Lake, Rainbow Lake, and Lago Los Osos—separated by levees.

Horseshoe Lake, the centerpiece, is stocked with trout, and efforts are underway to establish a self-sustaining fishery for largemouth and smallmouth bass. The lake quickly responds to trout plants, providing fruitful opportunities for anglers from both boats and shore. Quarry Lakes offers amenities such as a small boat launch, picnic areas, a swimming area, a snack bar, and a beach with wheelchair access.

Despite its allure, Quarry Lakes faces challenges, notably the wind that can howl through the area, making fishing difficult. The best months to visit include the first break of warm weather in February and again in March, avoiding the foggy mornings and windy afternoons of late May through July. Additionally, all boats must undergo inspection and certification to ensure they are free of mussels before launching into the lake.
