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

Lake Guasti:

  1. Trout:
    • Renowned for rainbow trout, stocked throughout the season from November to April. Prime times for action are mornings and evenings near inlets and deeper areas. Fly fishing with lures like nymphs and streamers is a favored method.
  2. Channel Catfish:
    • Summertime (May to September) brings catfish into the spotlight. Nightcrawlers, stink bait, and cut bait prove effective, especially near the bottom. Expect thrilling battles with these whiskered giants.
  3. Crappie:
    • Crappie inhabit the shallows and structures. Live minnows or small jigs are irresistible, offering fast-paced fun for both kids and adults.
  4. Bluegill:
    • Feisty panfish near docks and coves. Worms and small lures will have them singing with joy, making them perfect for beginners.

Lake Cucamonga:

    • Similar to Guasti, catfish rule the warmer months (May to September). Nightcrawlers, stink bait, and cut bait are their go-to snacks. Be ready for powerful pulls and tasty fillets.
  2. Bass:
    • Largemouth bass are year-round residents, patrolling coves, weed beds, and rocky structures. Early mornings and evenings are best. Crankbaits, jigs, and plastic worms are their weaknesses. Expect acrobatic jumps!
