The Johnston Brief
The Iowa DNR knows exactly what's in these waters - it just buries the data in a clunky website. So we pulled it out. Below is every public pond, lake and river within about 30 minutes of Johnston - 10 of them, from Terra Lake right in town to the big metro reservoirs - each with the real fish sizes from DNR biologist surveys. Tap the fish you're after and it'll show you where to go.
Closest to home, Terra Lake at Terra Park sits right in town with an accessible pier - and it's the trout spot, stocked with rainbows November through April. Chasing more trout? Lake Petocka (Bondurant) gets stocked rainbows too. Want a wall-hanger bass? Try Big Creek or Blue Heron Lake out west. Going big with a boat? Saylorville is on Johnston's doorstep, with Big Creek and Easter Lake adding walleye, catfish and more. Use the finder below to filter by what you want to catch.
Fish sizes are from Iowa DNR Fish Iowa electrofishing surveys - biologists sampling each water and measuring what they find - plus DNR stocking records. Access, amenities and addresses come from the city and county park agencies that own each water (Johnston, Des Moines, West Des Moines, Pleasant Hill, Bondurant, Polk County Conservation) and, for Saylorville and Big Creek, the U.S. Army Corps of Engineers. These are all public, government sources - not crowd-sourced catch apps, which we avoid on purpose. Survey data tells you what's in the water and how big; it's not a log of individual catches, and clear water or timing can hide the biggest fish. Drive times are approximate from central Johnston.

Right in town: Terra Lake at Terra Park, the Des Moines River tailwater below the Saylorville dam, and the big Saylorville Reservoir on Johnston's doorstep. A short drive: Big Creek Lake (Polk City) and Lake Petocka (Bondurant). Farther across the metro (still ~20-30 min): Gray's Lake and Easter Lake (Des Moines), Blue Heron Lake (Raccoon River Park, West Des Moines), Copper Creek Lake (Pleasant Hill) and Banner Lakes at Summerset. The finder above sorts all 10 by drive time.
For the widest size range, Big Creek runs 8-19.5″ with most between 12.5 and 17″. Blue Heron Lake out west is a strong bass fishery to 20″, and Easter Lake fishes best from 12-16″.
Terra Lake at Terra Park, right in Johnston, gets stocked with catchable rainbow trout Nov-April - the closest reliable cold-season trout around. Lake Petocka in Bondurant is stocked too. You'll need a trout fee added to your Iowa license to keep them.
Yes - anyone 16 or older needs an Iowa fishing license, plus a trout fee to keep trout. Kids under 16 fish free. Confirm current limits at iowadnr.gov before you go.
