Big Birch and Little Birch: A Property Buyer's Map Check

Big Birch and Little Birch are separate lakes near Grey Eagle, and Little Birch is actually the deeper of the two. A useful property comparison starts with each lake's DNR identification number, then moves to the specific shore, access route and parcel jurisdiction. Neither the word “Birch” nor a Grey Eagle mailing address tells you enough to evaluate a home.

I would keep two map folders open while comparing listings: one for the lake itself and one for the land being sold. Our Big Birch Lake property page and Little Birch Lake property page provide separate starting points. For help organizing a shortlist around your intended use, contact Janet.

Put the correct lake number on every document

The DNR's LakeFinder records identify Big Birch as 77-0084-00 and Little Birch as 77-0089-00. Their reported surface areas and maximum depths differ substantially. The following figures come from those individual DNR records, checked September 22, 2026, with area rounded to whole acres. Big Birch DNR record, Little Birch DNR record.

That depth comparison is a useful correction to an easy assumption: a larger lake is not necessarily deeper. It does not establish the water depth off a particular dock, the bottom material at a swimming area or the length of a usable boating season. Those questions belong to the individual shore.

Label saved depth maps, water-quality reports and seller correspondence with the full number. If a document simply says “Birch Lake,” resolve the identity before treating it as evidence. This is especially useful when an owner has assembled paperwork from several properties over many years.

Compare actual access points, not just an access count

Todd County's lake-access inventory lists a concrete ramp for Big Birch at 10880 Angler Drive and a concrete ramp for Little Birch at 27535 Amber Drive. It identifies both listed locations with Birchdale Township. These are practical places to locate on a road map before touring; the inventory is not a promise that a particular ramp will suit every trailer or water level. Todd County lake and access inventory.

If you trailer a boat, drive the approach with that use in mind. Look at turn geometry, where vehicles wait and whether you can comfortably reverse. Check posted conditions on the day of use. A ramp that is close in straight-line distance may require a different road approach from the house you are considering.

If you expect to keep a boat at home, the questions change. Walk the route from storage to shore, identify where dock sections would go over winter and ask how the existing owner handles installation. Public access nearby does not give a back-lot owner permission to use a neighbor's shoreline. Our explanation of public, deeded and waterfront access separates those rights.

Turn the mailing address into a parcel location

Use the parcel number to open Todd County's GIS viewer when the property is in Todd County. Available layers include parcel boundaries, plats, zoning and address points. The county explicitly says its mapping is a reference tool, not a legally recorded map or survey. Todd County interactive mapping.

Record the county, township or city, parcel number and legal description. Do not assume the county label in a lake database identifies the government responsible for every surrounding lot. If your map search reaches a county boundary, continue the parcel search with the government on the property's side of that boundary.

This produces better questions than “Can I add a garage on Big Birch?” Bring the actual parcel, proposed garage position, driveway and septic layout to the appropriate planning office. A mailing town is useful for deliveries; the governing jurisdiction and recorded land description are what let officials identify the site.

For a narrow or irregular lot, compare GIS with the plat and any available survey. Check whether the road separates two pieces of the property and whether shore access crosses another owner’s land. The survey reading checklist explains which lines and notes deserve a closer look.

Read the shore before ranking the lake

At each showing, take notes from the house, the top of the slope and the water's edge. Record the number and condition of steps, the walking surface, places where runoff concentrates and the effort involved in carrying equipment. A level-looking aerial photograph can conceal a difficult final approach.

Then connect the depth map to an on-site conversation. Ask where the owner places the lift, what happens during lower water and whether moving the dock has ever been necessary. Request dated photographs from more than one season. Treat an answer about the whole lake as background until you can connect it to this frontage.

Consider your own routine rather than assigning a universal winner. A household that launches occasionally may prioritize garage space and a straightforward ramp route. Someone who uses a kayak every morning may care more about the last few feet from the lawn to the water. Those preferences can reverse the order of two otherwise similar properties.

Keep environmental records distinct from appearance

LakeFinder currently lists zebra mussels for Big Birch and both zebra mussels and Eurasian watermilfoil for Little Birch. These listings identify issues to investigate; they do not measure conditions along a particular frontage on a particular day. Use the DNR records linked above and review the date and location of any additional survey.

The DNR also cautions that LakeFinder does not contain every survey immediately; processing and posting take time. A missing recent report is not evidence that nothing changed. DNR LakeFinder information and limitations.

Ask a seller for plant-management permits, work invoices and photographs identifying the treated area. Separate recurring expenses from one-time work. If a buyer's plan depends on a clear swimming area, inspect that exact area during the relevant season and investigate whether the intended management is allowed.

A useful comparison sheet for two showings

For each property, write down the lake ID, parcel jurisdiction, actual frontage, legal access, preferred launch, slope to water and available equipment storage. Add one column for documented answers and another for questions still open. Keep “owner says” separate from a recorded agreement, survey or permit.

After the visits, choose three features you would use every week and three costs or limitations you would have to manage. This makes the decision about the property you will own instead of a competition between lake names. I can help compare that worksheet with your lake-home buying priorities; send me the properties you are considering.
