Reservoir Fishing: How to Ace Spot Selection (Part 1) – Pro Tips from a Seasoned Angler

Why Reservoir Fishing Spot Matters More Than You Think

Let me tell you a frustrating story: Last month, I spent 3 days at a new reservoir, armed with my “secret bait recipe” and a fancy rod setup. I even skipped lunch to sit by the water, convinced I’d hook a monster carp. But guess what? I caught… nothing. Zero bites. Meanwhile, the guy next to me, who just used basic corn kernels and a simple float, pulled in 5 big bass in an afternoon. Later, he laughed and said, “Bro, I just picked the right corner of the lake. You’re fighting the wind and the wrong shape, not the fish.”

That’s when I realized: In reservoir fishing, your spot is 80% of the battle. It’s not about how expensive your gear is or how “scientific” your bait is—it’s about where the fish are naturally hanging out. And that’s all tied to the reservoir’s shape and the wind. So today, let’s dive into the first part of my reservoir spot selection guide, with real examples and tips that actually work.

First, Let’s Understand Reservoir Shapes (It’s Not Just About the Water)

Reservoirs come in all weird and wonderful shapes—some look like a simple rectangle, others like a maze of fingers. But there are only 6 main types, and each one dictates where fish will gather. Let me break them down for you:

• “I” or “One”-shaped: Long and narrow, like a straight line between two hills.
• “Y” or “People”-shaped: A main body with two long arms branching off, like a “Y” or a person’s legs.
• Conical: Broad at the top, tapering down to a point (like a cone).
• One-big-one-small: A wide end and a narrow end, like a bullet.
• Wide oval/rectangle/circle: A large, open body with minimal branches.
• “M” or “Star”-shaped: Lots of small arms branching off, like a starfish.

Now, the key is to visualize the wind and fish movement. In the diagram below (from my field notes), the red dots are sunrise, yellow are sunset, white arrows are common winds, and green letters mark “safe zones”—not where you fish, but where we’ll analyze.

Picking Spots for Specific Reservoir Shapes

Let’s start with the most common ones: the “I” shape and the “Y” shape. These are the easiest to mess up if you don’t study the water flow.

1. “I” or “One”-shaped Reservoirs

Imagine a long, straight lake between two mountains—like a canal. Here’s the thing: Wind is your best friend (or worst enemy). If the wind blows from the left, the water will push right, and fish will follow that current. Let me explain:

• Common winds: Usually from the left (as shown in the diagram). So fish will swim from the dam side toward point C, following the current.
• Big wind days: Fish will hug the inner bays on the right side of C (the “sheltered” area). That’s where they’ll hide from strong winds and feed.
• Calm days: If it’s a light breeze or no wind, fish spread out. Look for shallow water near grassy edges (EC area) or the AB/ED zones.
• Sun exposure: AB and ED areas get afternoon sun—great for warm-weather fish, but avoid if it’s too hot (fish get skittish). EC is your best bet for mixed conditions.

Pro tip: If you’re using a hand rod, stick to EC. If you’re casting, the inner bay near C’s right works even better. Trust me, I’ve lost more fish to bad spots here than I’d like to admit!

2. Y-shaped or “People”-shaped Reservoirs

These are trickier because there are two “arms” for fish to choose from. Let’s use the diagram again (green letters G, F, J):

• Skip G and J: These are near buildings/docks where fish can’t swim freely. They’re too crowded for a good bite.
• Focus on the left arm: The left branch is longer and has fewer structures, so fish can move through it easily. The right arm (F) is the widest part—too open for most hand rod fishing (unless you’re using a float and casting far).
• Check shallow vs. deep: The narrowest part of the Y (between G and F) is key. Shallow water there means fish can ambush prey, but make sure it’s deep enough to hold a school.
• Wind direction matters: If wind blows from the dam (right side), the left arm’s inner bays (near F) will catch the current. That’s where you want to be!

Here’s my golden rule for Y-shaped spots: Fish love corners where the water narrows and the wind brings food. Avoid the super wide parts (like F) unless you’re using a long cast. And don’t waste time on windy days—fish will huddle in the sheltered arms!

Final Thoughts (and a Tease for Next Time)

Choosing a reservoir spot is like solving a puzzle—you need to read the water, wind, and shape all at once. Remember: It’s not just about picking a spot near a tree or a rock. It’s about following the fish’s natural path, which is shaped by the wind and the lake’s own “layout.”

Stay tuned for Part 2, where we’ll tackle the conical, bullet-shaped, and oval reservoirs—plus tips for the “star” and “maze” ones. Until then, go test these tips at your local reservoir. And if you catch a monster bass, send me a pic—I’d love to see it! (Just no, I won’t share my secret bait recipe yet… you need to earn it first.)
