WDFW Puget Sound Interactive Creel Survey Dashboard

📊 Metrics Explained

Total Catch

The absolute number of fish caught. Shows overall production volume for an area or time period.

CPUE (Catch Per Unit Effort)

Fish caught per angler interviewed. Formula: Total Fish ÷ Total Anglers. Higher values indicate more efficient fishing. Example: 7.5 CPUE means each angler averaged 7.5 fish.

Skunk Probability

Estimated probability that a fishing party (boat or shore group) catches zero fish. Calculated using a Poisson model: e-λ where λ = total catch ÷ total interviews (avg catch per party). Lower is better! Example: 12% means roughly 88% of parties are expected to catch at least one fish.

Success Rate

Estimated probability that a fishing party catches at least one fish. Formula: 1 − Skunk Probability. Uses the same Poisson model as the Trip Planner for consistency. Example: 88% means roughly 88 out of 100 fishing parties are expected to catch something.

Hotness Score

Composite metric that combines total catch volume, catch rate (CPUE), and success rate into one score. Areas with high values across all three metrics rank highest. Perfect for finding the overall best fishing spots.

Success Window

Time periods when catch rates are high but crowds are low. Look for gaps where the red line (success) is high and the purple area (crowds) is low. These are prime fishing opportunities!

📈 Charts Guide

Catch Trends Over Time

Shows how catches have changed over time for each species. Use to identify seasonal patterns or long-term trends.

Total Catch by Species

Pie chart showing proportion of each species caught. Quickly see which species dominate the fishery.

Top 10 Catch Areas

Compare fishing areas by four metrics (use the icon buttons to switch):

• Total Catch (∑): Find most productive areas (highest volume)
• Catch Rate (⚡): Find most efficient areas (best success per angler)
• Skunk % (🦨): Find most reliable areas (lowest chance of catching nothing)
• Hotness (🔥): Find overall best spots (composite score of volume, rate, and success)

Tip: An area might rank #1 in Total Catch but #8 in Catch Rate - meaning lots of fish being caught and it's crowded!

Catch Distribution

Shows species catches broken down by time period. Adapts to your Time Granularity selection (Yearly/Monthly/Weekly/Daily).

Success Window

Dual-axis chart revealing when fishing is good but not crowded:

• Red Line (left axis): Catch rate - higher is better
• Purple Area (right axis): Total anglers - shows crowd size
• The Sweet Spot: Red line peaks above purple area = excellent fishing with few competitors!

Fishing Spots Layer

The layers control in the top right corner of the map includes a "Fishing Spots" toggle that shows popular salmon fishing locations throughout Puget Sound. These are well-known productive spots where anglers frequently target salmon.

• Toggle on/off: Use the "Fishing Spots" checkbox in the map's layers control to show or hide fishing spots
• Zoom to see names: Spot labels only appear at zoom level 12 or closer (zoomed in)
• Click for details: Click any marker to see the spot name in a tooltip
• Use in Trip Planner: Many of these spots have optimal fishing time predictions (see Optimal Fishing Times section below)

🧭 Trip Planner Guide

Trip Planner is a guided 5-step wizard that analyzes your preferences and recommends personalized fishing opportunities. Use it when planning a specific trip with set dates and priorities. Switch to Trip Planner mode using the toggle in the dashboard header.

The 5-Step Wizard

Step 1: Pick Timeframe

• Add one or more date ranges (e.g., "July 4-10")
• Optional labels for each timespan (e.g., "Summer Vacation")
• Set fishing window size (default: 3 days) - subdivides date ranges into smaller periods
• Example: 14-day vacation with 3-day windows = 5 possible fishing windows

Step 2: Select Species

• Individual Mode: Select species in priority order (drag to reorder)
• Custom Groups Mode: Create up to 3 groups combining multiple species (e.g., "All Salmon")
• Groups help reduce planning budget by treating multiple species as one option
• Higher-priority species/groups get more weight in recommendations

Step 3: Choose Location

• Select marine areas in priority order
• List View: Select from alphabetical area list with drag-to-reorder
• Map View: Click areas on interactive map to add them
• Higher-priority areas get more weight in recommendations

Step 4: Set Priorities

• Drag-and-drop category weighting (top = highest priority)
• Default: Species 50%, Location 35%, Timespan 15%
• Affects how recommendations are scored and ranked
• Tip: Put your non-negotiable preference first (e.g., if dates are fixed, prioritize Species or Location)

Step 5: Your Recommendations

• Three personalized recommendation cards tailored to your priorities
• Each card shows: Species, Location, Timeframe, key metrics (Catch Rate, Success Rate, Avg Anglers, Total Catch)
• Overall Score (0-100) and Confidence Level (based on sample size)
• Click "View Detailed Data" to jump to Explorer with that recommendation's filters pre-loaded

Understanding Recommendations

🎯 Top Priority Match

Best option for your highest-weighted preference. Optimizes for what you care about most.

⚖️ Balanced Tradeoff

Good compromise across all factors. Solid performance in species, location, and timeframe.

💎 Best Value

High success with lower crowds - the hidden gem. May sacrifice volume for better fishing experience.

Key Concepts

Planning Budget (500 max):

• Formula: Species × Areas × Windows Across Timespans
• Example: 3 species × 5 areas × 10 windows = 150 scenarios ✓
• Example: 5 species × 10 areas × 15 windows = 750 scenarios ✗ (exceeds limit)
• If exceeded, a modal suggests specific reductions

Budget Management Strategies

Use Species Groups (Most Effective)

Switch to "Custom Groups" mode in Step 2. Create a group like "All Salmon" (chinook + coho + pink + sockeye + chum). This reduces 5 species to 1 group, cutting budget by 80%! Groups are the #1 way to stay under budget.

Increase Fishing Window Size

Change from 2-day windows to 3-4 day windows in Step 1. Fewer windows = lower budget. Trade-off: less granular recommendations.

Select Fewer Areas

Focus on 3-5 top areas instead of 10+. Quality over quantity - better to analyze a few areas deeply.

Shorten Date Ranges

Instead of analyzing Apr-Oct (7 months), focus on peak season (Jun-Aug). Fewer days = fewer fishing windows.

Real Example: If budget shows 620/500, you could: (1) Create an "All Salmon" group → drops to 124/500 ✓, or (2) Change from 3-day to 4-day windows → drops to 465/500 ✓.

Fishing Windows:

• Subdivides date ranges into smaller periods for analysis
• Example: 14-day vacation → 7 two-day windows → finds optimal sub-periods
• Smaller windows = more precision but uses more planning budget
• Larger windows = broader recommendations, lower budget usage

Priority Weighting:

• Determines how recommendations are ranked
• Top category gets 50% of score, middle gets 35%, bottom gets 15%
• Drag to reorder based on what you won't compromise on
• Example: If dates are fixed, prioritize Species or Location highest

Trip Planner vs Explorer

Use Trip Planner when:

• Planning a specific trip with set dates
• Want guided, personalized recommendations
• Need to balance multiple priorities (species, location, timing)
• Want side-by-side comparison of best options

Use Explorer when:

• Casually browsing historical data
• Deep-diving into specific areas or species
• Analyzing long-term trends
• Comparing custom metrics across areas

Quick Start

1. Toggle to Trip Planner mode using the switch in the dashboard header
2. Add timespan: "Aug 15-22, 2026" labeled "Summer Vacation"
3. Select species: Chinook (1st priority), Coho (2nd priority)
4. Pick 3-5 favorite marine areas from list or map
5. Keep default weights (Species 50%, Location 35%, Timespan 15%) or adjust
6. Review three personalized recommendations
7. Click "View Detailed Data" on any recommendation to explore further in Explorer mode

Pro Tips

• Budget Management: Create species groups (e.g., "All Salmon") to reduce permutations significantly
• Window Optimization: Start with 3-day windows, refine to 2-day windows if needed
• Area Selection: Include diverse areas for better recommendations - mix popular and off-the-beaten-path locations
• State Persistence: Selections auto-save and restore on page refresh - never lose your progress
• Restart Anytime: Use ↻ Restart button to clear all selections and begin fresh
• Seamless Integration: "View Detailed Data" loads Explorer with recommendation filters pre-applied for deep analysis

🎣 Optimal Fishing Times (Slack Currents)

What Are Slack Currents?

Slack current is the brief period when tidal currents reverse direction and water movement is minimal. During these windows, fishing conditions are often optimal because:

• Fish are more actively feeding (less energy fighting current)
• Bait is easier for fish to catch
• Your gear drifts naturally without being pulled by strong currents
• Boat positioning and control is easier

How to Use This Feature

1. Complete Trip Planner wizard with future dates (past dates won't show predictions)
2. Look for green fishing spot tags in your recommendations
3. Click any green tag - a side panel slides in from the right
4. View timeline visualization showing 2-hour fishing windows for each day
5. Plan your trip to arrive 1 hour before slack and fish through the window

Understanding the Timeline

The timeline shows horizontal bars representing 2-hour fishing windows (1 hour before + 1 hour after slack). Each window is color-coded and positioned by time of day:

• X-axis: Time of day (3am to 10pm)
• Y-axis: Each row represents one day
• Bar colors: Different colors for multiple windows on same day
• Hover for details: Shows exact slack time, fishing window, and current type

Current Types

You'll see two types of slack currents in the predictions:

• Before Flood: Slack period before current begins flowing in (toward shore/inland). Often excellent for fishing.
• Before Ebb: Slack period before current begins flowing out (toward open ocean). Also productive for fishing.

Note: Both types are good for fishing - fish the slack window regardless of flood/ebb cycle!

Important Notes

• Accuracy: Predictions have ±15-30 minute error margin. Slack currents are estimates, not guarantees.
• Data Source: Uses NOAA Tides & Currents API with multiple nearby current stations per spot (where available).
• Future dates only: Past fishing windows show as non-clickable gray tags.
• Not all spots covered: Some fishing spots don't have nearby NOAA current stations - these won't show predictions.
• Weather impacts: Strong winds, storms, and unusual weather can shift actual slack times.
• Best practices: Cross-reference with NOAA tide charts for critical trips and be prepared for timing variations.

Troubleshooting

Tags aren't clickable: Ensure your fishing window includes future dates. Past dates don't show predictions.

Panel shows error: NOAA API may be temporarily unavailable, or the fishing spot has no current stations configured. Try again later or check a different spot.

Times seem off: Remember there's a ±15-30 minute error margin. Slack current predictions are estimates based on tidal models and may vary from observed conditions.

📍 My Spots - Personal Fishing Spots

My Spots lets you draw and save your own fishing areas directly on the map. Each spot automatically gets NOAA current stations assigned so you can get fishing time predictions immediately — the same slack current system used by the curated Fishing Spots layer.

Getting Started

1. Open the panel: Click the orange + My Spots button in the map header.
2. Draw a spot: Click Draw New Spot, then click the map to place polygon corners. Double-click to close and finish the shape.
3. Fill in the form: Give your spot a name, confirm the catch area (auto-detected from your polygon location), and add optional notes such as depth or best season.
4. Save: Click Save Spot. The spot appears on the map immediately in orange.

Using Your Spots

Fishing Times

In the Trip Planner, your personal spots appear as orange tags in the Known Fishing Spots section of recommendation cards. Click an orange tag (for a future date) to see optimal slack current windows for that location — the same prediction system used by the curated fishing spots.

Zoom to Spot

Click Zoom on a spot card to pan and zoom the map to that spot. Spot name labels appear at zoom level 12+.

Show / Hide All

Use the My Spots checkbox in the layers control, in the top right corner of the map, to show or hide all your personal spots at once.

Delete

Click Delete on a spot card and confirm to permanently remove it from your browser.

Current Stations & Fishing Times

When you save a spot, the app automatically finds the nearest NOAA current stations (up to 5, within 16 km). A pathfinding algorithm avoids routing through land, so stations across a bay won't be assigned if a closer one exists on the same water body. These stations power the slack current predictions for your spot.

The station status indicator in the save form shows how many stations were found. If no stations are found within range, fishing time predictions won't be available for that spot.

Submitting to the Community

Found a great spot you'd like to share? Click Submit on a spot card to open a pre-filled GitHub issue with your spot's geometry and metadata. An admin will review it and may add it to the shared dataset. Submission is optional — your spots stay private unless you choose to submit.

Privacy & Storage

All spots are stored in your browser's localStorage only. They are never sent to a server and are not visible to anyone else. Clearing your browser data will delete your saved spots — there is currently no export or backup.

Tips

• Draw your polygon to match your actual fishing area — accurate shapes improve current station assignment.
• The catch area is auto-detected from your polygon location but can be changed in the dropdown if needed.
• Add notes (depth, tide conditions, best months) to remember what makes each spot productive.
• Spot labels appear at zoom level 12+. Zoom in to see names on the map.
• You can have multiple spots and toggle them all on/off with the My Spots checkbox in the map's layers control.

🔍 Tips & Tricks

• Mode Switching: Toggle between Explorer and Trip Planner modes without losing progress - your selections in each mode are saved automatically!
• Multi-Select Shortcuts: Use "✓ All" and "× Clear" buttons above dropdowns for quick selections. Selected items appear as tags above the dropdown with removable × buttons.

⚠️ Understanding the Law of Small Numbers

What is it? The Law of Small Numbers is the tendency for small samples to show extreme or unusual values purely by chance, even when no real pattern exists.

Why it matters for fishing data: When an area or time period has very few anglers interviewed, the statistics can be misleading:

• Example 1: Area shows 15 fish/angler CPUE, but only 3 anglers were interviewed. This could easily be random variation!
• Example 2: Area shows 0% skunk rate, but only 5 anglers surveyed. A few more interviews might reveal a different picture.
• Example 3: Weekly data shows huge spike in catch rate, but that week had only 2 interview days due to weather. Not representative!

How to interpret data responsibly:

1. Check the sample size: Hover over chart points to see "Total Anglers" - this is your sample size
2. Be skeptical of extremes with small samples: If you see an amazing catch rate but only 10-20 anglers, treat it as "interesting but unproven"
3. Prefer areas/times with larger samples: 500+ anglers interviewed gives much more reliable statistics than 50 anglers
4. Look for consistency: An area that shows good catch rates across multiple years/months is more reliable than a one-time spike
5. Use multiple metrics or Hotness: The Hotness (🔥) score helps by combining metrics - areas ranking high in Hotness typically have larger sample sizes and consistent performance. You can also check if an area ranks high in Total Catch, CPUE, AND low Skunk % individually.

Red flags for small sample issues:

• 🚩 Daily or weekly granularity with extreme values (sample likely very small)
• 🚩 Obscure areas with impressive stats (fewer anglers = less data)
• 🚩 Early/late season spikes (fewer fishing days = fewer samples)
• 🚩 Perfect scores (0% skunk or 100% anything) with limited data

This doesn't mean small sample data is useless - it's great for generating hypotheses ("Maybe Area 13 is worth exploring!"), but confirm with larger datasets or personal experience before relying on it.

❓ Frequently Asked Questions

What's the difference between the metric buttons?

Each metric measures different aspects of fishing success:

• Total Catch (∑): Pure volume - best for finding productive areas
• Catch Rate (⚡): Efficiency - average fish per angler
• Skunk % (🦨): Reliability - chance of catching nothing
• Hotness (🔥): Composite score - combines all three for overall best spots

When should I use Hotness vs individual metrics?

Use Hotness (🔥) for a quick overview of the best all-around areas. Use individual metrics when you have specific priorities: Total Catch if you want volume, Catch Rate for efficiency, or Skunk % for reliability.

Why do different metrics show different "top 10" areas?

Each metric measures different aspects. An area with high total catch might have moderate CPUE (because it's very popular/crowded). The Hotness score helps identify areas that excel across multiple dimensions.

What does "skunked" mean?

Catching zero fish. The Skunk Probability is the estimated chance that a fishing party (boat or shore group) catches nothing, modeled using a Poisson distribution from historical party interview data.

How is catch rate calculated?

Total fish caught divided by total anglers interviewed in the surveys. It represents the average fish per angler.

Why doesn't the Success Window show my area?

The chart shows data across all areas (or your selected areas). To see a specific area's success window, use the Catch Area filter to select just that area.

What's the difference between Explorer and Trip Planner modes?

Explorer (default) is a flexible dashboard for freely exploring historical data with custom filters and charts. Trip Planner is a guided 5-step wizard that analyzes your preferences (dates, species, locations, priorities) and recommends specific fishing opportunities. Use Trip Planner when planning a trip, Explorer when researching patterns.
