What Should You Record in a Fishing Log Besides Weather?

A fishing log is most useful when it helps me answer a simple question: what was different when the fish started biting? Weather matters, but it rarely tells the whole story. Two days with similar temperatures, clouds, and wind can fish completely differently because the water level changed, bait moved, or I finally put my lure at the right depth.

I don’t try to record every last detail. That turns a relaxing day on the water into paperwork. Instead, I note the observations that can help me make a better decision on the next trip.

Record the water, not just the sky

Weather describes the conditions above the surface. The fish live below it, so water conditions deserve at least as much attention.

Water level and flow

Note whether the water is low, normal, high, rising, falling, clear, or carrying extra current. On a river, I’ll also describe the current as slow, moderate, or strong and note where I found protected water.

Water level changes where fish can comfortably hold. Rising water may put fish shallow around newly flooded cover. Falling water can pull them toward channel edges, deeper banks, or remaining cover. In lakes and ponds, a noticeable change in level can alter the depth of docks, weed edges, and shoreline brush that usually produce.

You don’t need exact measurements every trip. A note such as “lake about 2 feet low; outside weed edge shallower than usual” is often enough to make a useful comparison later.

Water clarity and color

Write down how far you could see into the water, even if your estimate is rough. For example:

Clear: bottom visible in 4 feet near shore
Slight stain: lure disappears around 18 inches
Muddy: visibility under 6 inches
Green with algae or tea-colored from runoff

Clarity affects lure visibility, fish positioning, and how close I need to put a bait to cover. It also helps explain why a lure that worked last month suddenly gets ignored. The fish may not have changed their preferences; the water may simply be carrying more color.

Surface temperature and temperature changes

If you have a thermometer, record the water temperature where you’re fishing. More important than chasing a perfect number is noticing the trend. Was the water warming through the afternoon? Did a cold rain cool down the shallows? Were protected pockets warmer than the main lake?

A temperature difference of only a few degrees can matter, especially in spring and fall. Note where you measured it: surface, shallow pocket, main-lake bank, creek arm, or river backwater.

Bottom and cover type

Describe what was under and around your bait when you got bites:

Rock, gravel, sand, mud, shell, or hard bottom
Grass, reeds, lily pads, submerged timber, brush, docks, or riprap
A steep drop, point, flat, creek channel, or shoreline pocket

“Caught fish on a green pumpkin worm” is a start. “Caught fish on a green pumpkin worm dragged across gravel at the outside edge of sparse grass” is a pattern I can actually try to repeat.

Track where the fish were in the water column

Many fishing logs mention the spot but leave out the depth. That’s one of the easiest ways to lose a useful pattern.

Lure depth and fish depth

Record both the water depth and the approximate depth of the lure when the strike came. These aren’t always the same thing.

If I catch a fish in 15 feet of water on a crankbait running 6 feet deep, the fish was likely using the upper part of the water column. If I catch one on a jig dragged along bottom in 15 feet, that tells a different story.

For bank fishing, simple notes work well:

“Bites came just beyond the first drop.”
“Bluegill were under the dock floats.”
“Bass hit in 2 to 4 feet beside flooded brush.”
“Catfish came from the deeper hole below the current break.”

Depth is especially valuable when a bite is scattered. It may show that fish weren’t relating to one shoreline or one lure—they were relating to a particular depth.

Casting angle and retrieve path

Casting angle is an overlooked detail. A fish holding along a weed line, current seam, dock, or rock bank may react better when the bait travels parallel to the structure rather than crossing it.

Make a quick note about the cast that worked:

Cast parallel to the bank
Retrieved upstream, downstream, or across current
Worked along the shady side of a dock
Cast past a laydown and brought the lure beside the trunk
Pitched to the outside edge of grass, not into the thick center

This is particularly helpful on rivers. A lure moving naturally with the current can draw strikes where the same lure pulled against current doesn't.

The position of the boat or bank spot

I like to note where I was standing or where the boat sat when the bite happened. A productive cast can be hard to recreate if I only remember the target and not the angle.

For example: “Boat in 12 feet, casting toward a 6-foot rock shelf,” or “Standing downstream of the bridge pier, casting into the slack pocket.” Those details can save a lot of trial and error on a return trip.

Document the bait activity you can see

Fish activity above the water often points to what is happening underneath it. I record what I see, hear, or find—not what I assume.

Look for details such as:

Baitfish flicking near the surface
Schools of shad, minnows, or other forage on a sonar screen
Bluegill beds or panfish moving through shallow cover
Crawfish along rocks or shoreline mud
Insects hatching or landing on the water
Birds feeding over bait schools
Surface boils, swirls, busting fish, or wakes in vegetation

Also note the size of the forage. If fish are chasing tiny baitfish, a large, loud lure may not be the best first choice. If you see larger shad or hear bluegill popping around grass, that can point you toward a different presentation.

A useful log entry might read: “Small shad dimpling in the backs of pockets from 7:30 to 8:15; bass struck a small swimbait near surface.” It connects a visible clue to a successful choice.

Write down the lure details that actually matter

It’s tempting to fill a log with brand names and colors, but the presentation usually matters more than a long list of tackle.

For every lure or bait that gets a bite, record:

Lure type and approximate size
Color or general appearance
Weight, hook style, or rigging when relevant
Running depth or sink time
Retrieve speed and cadence
Pauses, twitches, hops, drags, or dead-sticking
Whether the lure contacted bottom, cover, or the surface

Instead of writing “spinnerbait worked,” try “1/2-ounce white spinnerbait slow-rolled beside windblown grass; strikes came after it clipped grass and popped free.” That gives you a repeatable presentation, not just a tackle label.

Note what failed, too

A fishing log shouldn’t only record success. The failed attempts often explain why the successful adjustment mattered.

I’ll jot down a few quick comparisons:

Fast retrieve ignored; slower retrieve got two strikes
Fish followed a bright bait but committed to a natural color
Topwater had short strikes; small soft plastic converted bites
Bites stopped when the sun hit the bank

You don’t need a catalog of every cast. Just capture the changes that produced a clear response.

Count missed strikes and describe them

Missed strikes are data, not merely frustration. A day with six short strikes and one landed fish may tell you more than a day with a single clean bite.

When you miss a fish, note what happened:

The fish bumped the lure but didn't take it
The fish followed to the boat or bank
The fish blew up on topwater and missed
The bite came on slack line
The fish grabbed the tail of a soft plastic
The hook didn't connect after a strike

Then record the adjustment you made, if any. You may find that short strikes improve when you downsize, slow down, add a trailer, change hook size, pause longer, or wait a moment before setting the hook. Other times, the fish simply aren’t feeding aggressively, and the log helps make that clear.

Mark the timing of every change

Fishing conditions are rarely static from dawn to dusk. The useful part of a log is often the sequence of changes, not the final totals.

Keep a rough timeline for:

First bite and last bite
Productive windows
Wind shifts or increasing wind
Cloud cover appearing or clearing
Water beginning to rise, fall, or muddy up
Baitfish becoming active or disappearing
A move from shade to sun on key cover
Boat traffic, noise, or fishing pressure increasing

For example: “No bites from 6:30 to 8:00 on main-bank rocks. Wind picked up at 8:15 and pushed into the south bank. Three fish came from windblown grass between 8:30 and 9:10.” That entry is more valuable than a simple catch count because it tells you what changed before the bite improved.

Include pressure and human activity

Fishing pressure can affect both fish location and how willing they are to bite. A brief note is enough:

Several boats working the same point
Bank access crowded after noon
Fresh footprints around a small pond
Heavy recreational boat traffic
Fish were feeding before the area got busy

This won’t explain every slow day, but it gives context. If a small public pond produces early and shuts down after other anglers arrive, that is a practical pattern worth remembering.

Check local rules before recording or returning to a spot
If you plan to keep fish, revisit a productive area, or share a location, check the current regulations for that water. Seasons, creel limits, size limits, access rules, and special-management areas can change. A good log should include the water name and access point, but it should also help you fish that place responsibly.

Add a short end-of-trip summary

At the end of the day, write two or three sentences answering these questions:

What pattern produced the most convincing bites?
What changed when the fishing improved or declined?
What will I try first next time?

Here’s a simple example:

“Three largemouth from the outside grass edge in 5 to 7 feet. Best bite was a slow Texas-rigged creature bait dragged through isolated grass clumps after the wind started pushing into the bank. Next trip, start on windblown grass and work slowly before trying open-water lures.”

That summary is where scattered observations become a plan.

A simple fishing log template

A notebook, notes app, spreadsheet, or voice memo all work. The best format is the one you’ll use after a long day. I’d keep the template short enough to complete in a few minutes:

Date and water:
Target species:
Time fished:
Water level, flow, clarity, and temperature:
Area and cover:
Water depth and lure depth:
Bait activity or visible fish activity:
Best lure and presentation:
Casting angle and retrieve path:
Bites, catches, follows, and missed strikes:
What changed during the day:
Best pattern and next-trip plan:

Let the log reveal patterns over time

The value of a fishing log builds slowly. One entry may not tell you much, but a handful of trips can reveal that fish on your favorite lake use a particular depth after a cold front, that river smallmouth favor current seams at a certain water level, or that your pond’s bluegill turn on around the first warm evenings of spring.

Start small on your next trip. Record the water level or clarity, the depth of your successful lure, any bait activity you notice, and one thing that changed during the day. After a few outings, you’ll have more than a record of the weather—you’ll have a practical guide to your own water.
