Monroe Lake Open Bass Tournament runs once a year in spring
The Monroe Lake Open Bass Tournament is an annual spring fishing event held on Monroe Lake in southern Indiana, near Bloomington. The tournament draws both local and traveling anglers who compete for cash prizes and bragging rights. The event typically takes place in April or May, though the exact dates shift year to year — you'll need to check with Monroe Lake Marina or the Indiana Department of Natural Resources for the current year's schedule.
The tournament is open to anyone with a valid Indiana fishing license. You fish from your own boat or rent one from the marina, and the competition runs from dawn until a set weigh-in time in the afternoon. Anglers keep their catch in a livewell and bring their fish to the official weigh-in station, where they're measured and recorded. The angler or team with the heaviest total weight wins the tournament division.

How to enter and what you'll need
Entry to the Monroe Lake Open Bass Tournament requires registration before the tournament date. You can register at Monroe Lake Marina, which sits on the north shore of the lake and handles most tournament logistics. Bring your valid Indiana fishing license when you register — you cannot fish without one, and the tournament staff will check it before you launch.
The entry fee covers your spot in the tournament and access to the weigh-in. Fees vary depending on whether you're fishing as an individual or as part of a team, and some tournaments offer a separate division for first-time competitors or younger anglers. Ask the marina staff which division matches your situation when you call to register.
You'll also need a boat — either your own or a rental from Monroe Lake Marina. If you're renting, reserve early, especially if the tournament falls on a weekend. The marina has a limited number of rental boats, and they fill up quickly during tournament season. Bring your own tackle, cooler, and livewell setup if you're using your own boat.
What Monroe Lake bass fishing is actually like
Monroe Lake is a 10,750-acre reservoir known for largemouth and smallmouth bass. The lake has shallow coves and deeper channels, which means bass hold in different spots depending on the season and time of day. In spring, when the tournament typically runs, bass move into shallower water to spawn, so you'll find them near vegetation, fallen trees, and rocky banks.
The lake can get crowded during tournament day, especially near popular launch areas and known fishing spots. Arrive early if you want to scout a location before the official start time. Water temperature in April and May usually ranges from the mid-50s to low 60s, so dress in layers and bring rain gear — spring weather on the water changes fast.
Bass on Monroe Lake respond well to crankbaits, soft plastics, and topwater lures in spring. Local tackle shops near the lake can tell you what's been working in the weeks before the tournament. If you're new to the lake, consider fishing it a few times before tournament day to learn where the structure is and how the bass are positioned.
Tournament rules and what disqualifies you
The Monroe Lake Open Bass Tournament follows standard bass tournament rules: you keep all legal-sized bass you catch during the competition window and bring them to weigh-in alive. Bass must meet the minimum size requirement — typically 12 inches for largemouth and smallmouth on Monroe Lake, though confirm this with the tournament director when you register, as rules can change.
You cannot fish before the official start time, and you must be back at the weigh-in station by the announced cutoff time. Late arrivals are typically disqualified. You also cannot use live bait — only artificial lures are allowed. If you're fishing as a team, both anglers must stay in the same boat during the tournament.
Violations like keeping undersized fish, fishing outside the designated time window, or using prohibited bait will result in disqualification. The tournament staff checks fish at weigh-in and may measure them to confirm they meet size requirements.
Prizes and divisions
Prize money is distributed to the top finishers in each division. The exact payouts depend on the number of entries and the entry fees collected, so they vary year to year. Typically, first place wins the largest share, with smaller payouts for second, third, and sometimes fourth place. Some tournaments also award a prize for the largest single fish caught, called the "big bass" award.
Divisions are usually split by boat type (jon boat versus larger bass boats) or by experience level (open division for all anglers, and a novice or youth division for first-time competitors or younger fishers). Fishing in a separate division means you compete only against others in your category, which gives newer anglers a fairer shot at winning.
Getting to Monroe Lake and where to stay
Monroe Lake is located about 15 miles south of Bloomington, Indiana, near the town of Harrodsburg. The main public access point is Monroe Lake Marina on the north shore, which is where tournament registration and weigh-in happen. From Bloomington, take State Road 45 south and follow signs to the lake.
If you're traveling from out of state or need a place to stay overnight, Bloomington has hotels, motels, and bed-and-breakfasts within 20 minutes of the lake. Some anglers camp at the lake itself — Monroe Lake has a campground operated by the U.S. Army Corps of Engineers, though sites fill up quickly during tournament weekends. Book camping ahead if you plan to stay overnight.
Preparing your boat and tackle before tournament day
Check your boat's fuel level and top off the tank the day before the tournament — you don't want to run out of gas while fishing. Make sure your livewell is working properly and that you have enough aeration to keep fish alive during the day. Test your bilge pump and check that all safety equipment is on board: life jackets, a fire extinguisher, and a first-aid kit.
Organize your tackle the night before so you're not scrambling in the dark at launch. Bring more lures than you think you'll need — you may lose some to snags or fish, and having backups keeps you fishing instead of tying new knots. Charge your phone and any electronics, and bring a headlamp or flashlight for the pre-dawn launch.
