A few years back, I found myself staring at a decent-sized lake on my land and wondering how to stop relying so heavily on shallow wells and municipal water for irrigation. That’s when I started experimenting with submersible irrigation pumps fed directly from the lake. What I learned — sometimes the hard way — is that picking the right pump size and type can make or break your watering setup, especially when you’re dealing with fluctuating water levels and varying crop needs.

Below, I’ll walk you through the models and sizes I’ve used over the years, mostly in the 1HP to 5HP range, and explain where each one shines. If you’re trying to build a reliable irrigation pump from lake system, maybe my experiences will save you some trial and error.

Why a Lake Makes Sense for Irrigation

Lakes are an underrated asset. Unlike wells, they tend to hold stable volumes year-round, and pulling from one means you’re not constantly dropping the water table. But there’s a catch: you need a pump that can handle lake water, which often carries debris, algae, and occasional silt. A submersible lake irrigation pump placed deep enough avoids most of the surface gunk and gives a cleaner flow.

From my own plots — a mix of row crops, orchard, and a decent vegetable garden — I’ve found that a submersible irrigation pump is usually the simplest route. Drop it in, wire it up, and you’re good to go. Compared to surface pumps, there’s less priming hassle and fewer cavitation issues.

1HP Submersible Irrigation Pump — Small Jobs, Low Fuss

When I first started, I tried a 1 hp irrigation pump on a section of my garden and a small greenhouse. Honestly, it was perfect for that scale. It drew water quietly from about 10 feet down in the lake and pushed it through a basic drip line without breaking a sweat.

What I liked:

Super low power draw — my electric bill barely noticed it.
Easy to haul out for cleaning at season’s end.
Handled light sediment okay, especially with a simple pre-filter.

This size won’t move enough water for big fields, but for a garden irrigation pump or keeping a few raised beds happy, it’s a solid pick. It’s also a cheap entry point if you’re testing the lakeirrigation idea.

2 HP SUBMERSIBLE Irrigation Pump — Sweet Spot for Mid-Size Areas

After expanding the garden and adding berry bushes, I stepped up to a 2 hp irrigation pump. I even ran across some 2 hp irrigation pumps for sale at a local dealer and snagged one after checking the specs. This one handled a wider pipe diameter and gave me noticeably better pressure.

I used it to feed a high pressure irrigation pumps zone for sprinklers and kept another zone on low pressure for drip. With a lake pump irrigation system layout I designed, I could switch zones without rewiring.

Where it worked best:

Orchards and small vineyards.
Larger home lawns or hobby farms.
Mixed agricultural irrigation pumpssetups where you want flexibility.

If you’re running an electric water pump for irrigation off singlephase power, the 2HP versions are generally easier to integrate than threephase units.

3 HP Submersible Irrigation Pump — Stepping Into Serious Territory

At one point, I took on a neighbor’s contract to irrigate a bigger hayfield. A 3 hp irrigation pump was the smallest unit that could keep up with the demand. I paired it with a pressure tank for irrigation system to smooth out surges, and it performed like a workhorse.

It handled longer runs of pipe and could push water uphill without losing much volume. I even used it as part of a centrifugal irrigation pump backup arrangement — not because it’s centrifugal (it’s submersible), but because I had a 10 hp irrigation pump on standby for extreme drought periods.

Key takeaway: If you’re moving from weekend gardening to real farm irrigation pumps, 3HP is where you start getting serious flow rates.

4HP & 5HP Submersible Irrigation Pump — Heavy-Duty Reliability

When our main crop area crossed into multiple acres, I went with 5 hp irrigation pump and later added a 5hp irrigation pump as a second unit for redundancy. These beasts pull water fast, and with proper filtration, they don’t choke on lake muck.

I set up a lake pump irrigation system with parallel lines so if one pump trips, the other keeps running. We also use them to fill a storage pond, which feeds our irrigation well pump during dry spells.

Why I chose 5HP:

Could support long pivotsprinkler runs.
Managed simultaneous lawn irrigation pumpand crop zones.
Gave us enough irrigation pressure pumphead to reach the farthest corners of the property.

Yes, the power draw is higher, but with an efficient electric irrigation pump controller, I schedule run times to avoid peak rates.

Other Sizes I’ve Tried Along the Way

5 hp submersible irrigation pump: Good middle ground between 1HP and 2HP; handy if your lake level dips in summer.
agriculture water pumplabels: Often marketing speak, but look for real GPM specs.
submersible irrigation pump systemdesign matters more than raw horsepower — pipe sizing, elevation, and filter mesh all change performance.

What to Watch Out For

Lake intake placement— I learned to anchor the suction hose away from the shoreline muck. Even a submersible lake irrigation pump can clog if it sucks in too much organic matter.
Power matching— Make sure your circuit can handle the amperage, especially for 3 hp irrigation pump and above.
Seasonal checks— Before winter, I pull the pump, inspect the impeller, and store it dry. Corrosion is a silent killer.

Building a System That Lasts

My current setup is a mix: 1 hp irrigation pump for the garden, 2 hp irrigation pump for berries, 5 hp irrigation pump for the big fields, plus a pressure tank for irrigation system and automated valves. Together, it’s a full irrigation pump system that rarely leaves me scrambling.

I’d say the best irrigation pump isn’t a universal answer — it’s the one matched to your water source, terrain, and crop needs. For me, tapping the lake with submersible irrigation pumps has been costeffective and reliable.

Helpful Resources

If you want deeper technical info, I’ve found these sites useful over the years:

org— Solid standards and guides on pump selection and safety.
Engineering ToolBox— Great for calculating flow rates, pipe friction losses, and pump curves.

Both helped me finetune my irrigation pump from lake layouts and avoid rookie mistakes.

Wrap-Up

From my trials, here’s my rule of thumb: Start small if you’re new, but plan for growth. A 1 hp irrigation pump can teach you the basics, but moving up to 2 hp or 3 hp opens real possibilities. When you’re covering serious acreage, 5 hp irrigation pump models give the muscle needed for uninterrupted watering.

Above all, treat your irrigation pump system like any other tool: regular care pays off. I’ve pulled pumps out of lakes caked in algae, cleaned them in the driveway, and had them running again in an hour. That handson time taught me more than any spec sheet.

So if you’re eyeing that lake on your land, grab a submersible irrigation pump, test your setup, and tweak as you go. It might just be the simplest, cheapest water source you’ve got.
