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.

Map & Fishing Location

Types of Fish You Can Expect to Catch at Don Castro Reservoir

  1. Rainbow Trout: The stars of the show during cooler months (October to April), these feisty fish are stocked by the East Bay Municipal Utility District (EBMUD). Target them near the dam or points using lures like Kastmasters or PowerBait.
  2. Largemouth Bass: Ambush predators lurking in the weeds and tules, bass come alive in warmer months. Crankbaits, spinnerbaits, and jigs work wonders, especially around the dam, rocky outcrops, or the east shore.
  3. Channel Catfish: Bottom-dwellers that put up a good fight and are excellent on the table. Look for them in deeper water or near the dam using cut bait or nightcrawlers, especially during the night hours.
  4. Sunfish: Abundant in the shallows, perfect for kids or anyone using light tackle. Crickets, worms, or small jigs around the docks or near lily pads will entice them.

Local Insights: Mastering the Art of Don Castro Fishing

  • Prime Fishing Times: Early mornings and evenings are optimal, especially for bass and trout.
  • Strategic Spots: Focus on the shoreline near the dam and coves, but don’t hesitate to explore by boat for access to hidden gems.
  • Bait Tactics: Trolling near the dam or baitcasting PowerBait near the inlets is a surefire way to attract stocked trout.
  • Trophy Bass Tips: For trophy-sized bass, fish the tules and rocky outcrops on the east shore with jigs or worms during low-light periods.
  • Catfish Strategies: Catfish love the deeper waters and cover near the dam at night. Nightcrawlers or cut bait fished on the bottom will grab their attention.
  • Sunfish Simplicity: Sunfish are easy to catch from the docks or shallow areas with simple baits like worms or crickets.

Specific Fishing Locations: Maximizing Your Opportunities

  2. Coves: Sheltered areas holding good populations of sunfish and bass, perfect for relaxed fishing.
  3. Points: With drop-offs into deeper water, the points are prime real estate for catfish and larger trout. Try bottom fishing with cut bait or lures.
