If you had the Shiawassee River State Game Area birding tour on your calendar for Saturday, April 11th, you will need to make other plans. The Michigan Department of Natural Resources has canceled the event after rising floodwaters made the St. Charles location inaccessible — and based on what is happening at the site right now, the timing could not have worked out any differently.
Flooding at the Shiawassee River State Game Area began last weekend, coinciding with the regional flood event that has affected communities across mid-Michigan. But unlike many flood situations where water peaks and then recedes, the water at the Shiawassee SGA has continued to rise. The DNR made the call to cancel the birding tour once it became clear that getting participants safely to and through the area was not going to be possible.
Why the Flooding Is So Significant Here
The Shiawassee River State Game Area sits at the confluence of five rivers — the Bad, Cass, Flint, Shiawassee, and Tittabawassee — all of which drain toward Saginaw Bay. When regional rainfall or snowmelt pushes water levels up across that entire watershed simultaneously, the volume of water converging on this location is enormous. The managed wetlands within the game area are specifically designed to hold that water — acting as a massive natural sponge that captures and stores floodwater that would otherwise spread across the surrounding landscape.
DNR wildlife biologist Cameron Dole put the scale of what these wetlands do into terms that are worth sitting with. One acre of wetland can store 1.5 million gallons of water. The Shiawassee SGA alone covers 10,000 acres of wetlands. Do that math and you start to understand what is happening out there right now — and why, without this wetland complex, much of Saginaw County would simply be underwater.
The Shiawassee SGA operates alongside the adjacent Shiawassee River National Wildlife Refuge, and together the two form a vast wetland complex that has been quietly protecting surrounding communities from the full brunt of flooding events for decades. When the water is high at the game area, that is not a failure of the system — it is the system working exactly as it is designed to. The wetlands are full because they are doing their job.
What That Means for the Birding Tour
For birding enthusiasts who had planned to participate in the spring tour, the cancellation is disappointing. Spring birding at a managed wetland complex like the Shiawassee SGA is a genuinely compelling experience — the convergence of five river systems and thousands of acres of managed wetland habitat creates exactly the kind of environment that draws migratory waterfowl, shorebirds, and wading birds in impressive numbers during spring migration. When the conditions are right, the species diversity can be remarkable.
The current flooding, while frustrating for the canceled tour, actually speaks to the ecological richness that makes the Shiawassee SGA such a valuable birding destination in the first place. Wetland birds are drawn to exactly this kind of environment — expansive, water-rich, and teeming with the aquatic invertebrates and vegetation that flooded wetlands produce in abundance. The irony is that from a wildlife standpoint, the flooded game area is probably spectacular right now. Getting to it safely is another matter.
The DNR has not announced a rescheduled date for the birding tour. Those interested in future events at the Shiawassee River State Game Area should monitor the DNR’s website and event calendar as conditions improve and the water recedes.
The Broader Flooding Picture
The flooding affecting the Shiawassee SGA is part of a regional event that has touched communities across mid-Michigan over the past week. While the wetland complex has been absorbing what it can, surrounding communities have still experienced flooding — and the DNR’s acknowledgment that much of Saginaw County would be underwater without the wetland system underscores just how much work those 10,000 acres are doing behind the scenes.
Flooding and its impact on infrastructure and land use has been a consistent thread across the Thumb region this spring. The Hume Township FEMA flood plain update earlier this year flagged that some Huron County properties not previously considered to be in a flood plain may now fall within one under updated federal maps — a reminder that water management and flood risk are ongoing community concerns that require both good infrastructure and accurate, current information to manage effectively.
At the infrastructure level, the Huron County bridge funding application targeting three county bridges — including structures over Moore Creek and the Pinnebog River — reflects the kind of ongoing investment in water-adjacent infrastructure that flood events make more urgent. Bridges over waterways that regularly flood need to be maintained to standards that account for that stress, and securing federal funding for that work is exactly the right response.
For birding enthusiasts wanting to stay current on conditions at the Shiawassee River State Game Area and find out when the spring tour might be rescheduled, the Michigan DNR’s events and programs page provides updated information on outdoor programming, tour schedules, and site access conditions across state game areas and wildlife refuges. And for those interested in learning more about the ecological importance of the Shiawassee wetland complex and the wildlife it supports, the Shiawassee National Wildlife Refuge maintains visitor information, wildlife checklists, and educational resources on the refuge adjacent to the state game area.
