## Frequently Asked Questions — Diamond Lake

### How big is Diamond Lake and how deep is it?

Diamond Lake is the largest lake in Cass County at roughly 1,078 acres. The maximum depth is 64 feet, though about 60% of the lake sits under 10 feet — a sandy-bottom, spring-fed lake with a reputation for unusually clear water.

### Where is the public access on Diamond Lake?

The DNR public access site is on the south shore off Lake Street. It has a launch pier, restrooms, and parking for about 60 rigs. A $24 annual or $6 daily Cass County launch permit is required and sold on-site.

### What's the deal with the island in the middle of Diamond Lake?

The privately-occupied island in the center of Diamond Lake — about 43 acres — is reached by a residents-only summer barge. The cottages on it predate most of the modern lakefront development. Sail Bay (the northeast inlet) is a designated no-wake zone.

### What fish are in Diamond Lake?

Per the Michigan DNR: largemouth and smallmouth bass, bluegill, black crappie, perch, rock bass, sunfish, northern pike, grass pickerel, and walleye. The clear water and deep holes support a quality sport fishery.

### Is there a boat-up restaurant on Diamond Lake?

Yes — The Sandbar at Diamond Lake is the lakefront food and drink spot. Two marinas operate on the lake: Diamond Lake Marina at 120 Follett Drive (rentals and fuel dock) and Park Shore Marina (fishing-boat and paddleboard rentals).

### Are there annual events on Diamond Lake?

The Diamond Lake Association fires its annual fireworks display from a barge on the Saturday of July 4th weekend. The Diamond Lake Yacht Club (dlycmi.org) runs sailing programs through the summer.

### How do I get on the Diamond Lake weekly fuel delivery route?

Text DIAMOND to (877) 257-FUEL. Reply Y to confirm SMS delivery alerts and we add you to Diamond Lake's weekly route. No credit card required to join — pay only when you actually order fuel. You can also sign up online at docksidefuelservices.com if you prefer.

### What kind of fuel do you deliver to Diamond Lake?

REC-90 ethanol-free marine gasoline — the recommended fuel for boats, jet skis, pontoons, side-by-sides, generators, and most outdoor power equipment. The lack of ethanol prevents phase separation in tanks that sit unused for stretches, which protects engines on lakeside properties that don't see daily use.

### How many gallons can be delivered to Diamond Lake in one day?

Up to 780 gallons per route (700-gallon truck plus 80-gallon Fuel Mule). Reservations are first-reserve, first-fill — once Diamond Lake's weekly route fills up, additional requests join a FIFO waitlist and auto-promote when a reservation cancels.

### Is there a delivery minimum on Diamond Lake?

No minimum gallons — the trip fee ($30 dockside or $15 curbside) is the same whether we fill 5 gallons or 100. Most customers order 20-50 gallons per trip. The flat trip fee covers the cost of bringing the truck to your lake; per-gallon pricing is the current REC-90 market rate plus $1.49/gal.
