Buying at Lake Anna: Due Diligence Checklist

Before You Make an Offer

Step 1: Confirm Public Side vs. Private Side in Writing

This is the first question, not the last. Before touring any Lake Anna waterfront property, confirm explicitly whether the parcel is on the public (cold) side or the private (warm/WHTF) side. A buyer who falls in love with a private-side property expecting full lake access will be disappointed — there is no boat passage between the two sides through the three earthen dikes, under any conditions. Confirm the side via the county GIS parcel viewer, not just the listing description. Get it in writing from the listing agent. Then decide whether the private side's warm water and winter fishing advantages suit your intended use, or whether you need the public side for full lake access.

Step 2: Verify the Dominion Use Agreement for the Dock

Ask the listing agent for the Dominion Energy Use Agreement number for any existing dock. If they cannot produce it, contact Dominion's North Anna reservoir coordination team at napsreservoir@dominionenergy.com or 540-894-2029 and ask about the structure at the property address. A dock without a current, valid Use Agreement is a liability that transfers with the property. Confirm not just that a Use Agreement exists but that the current dock configuration matches what was approved — sellers who modified a dock without obtaining a modification approval have a non-compliant structure.

Step 3: Research the Algae History for the Specific Cove or Area

Check SwimHealthyVA.com for the current and historical HAB advisory map specific to the property's location. The upper North Anna Branch (above Route 522), the Pamunkey Branch, and Terry's Run have been the consistently affected areas. The lower main lake near the dam and most of the Spotsylvania shore have been far less affected. A property in the upper arms requires honest assessment of summer swimming advisory risk; a property on the lower lake does not carry the same history. The Lake Anna Civic Association (LACA) also publishes water quality monitoring data and HAB remediation updates at lakeannavirginia.org.

Step 4: Confirm the Taxing County

The mailing address does not determine the taxing county. Use the Louisa, Spotsylvania, and Orange County GIS parcel viewers to confirm exactly which county's tax rolls the parcel appears on. The rate difference between Orange ($0.620) and Spotsylvania ($0.734) per $100 is $1,140 per year on a $1 million property. This is a two-minute check that prevents a multi-year tax surprise.

Step 5: Check Hydrilla and Siltation in the Cove Approach

In 2025, hydrilla spread significantly through Lake Anna's upper arms and coves. A property in an affected area may have clogged boat approaches that make routine boating difficult without a full-size powered boat and a willingness to motor slowly through vegetation. Ask the listing agent about hydrilla conditions specifically in the cove or dock approach. Also ask about water depth and siltation at the dock — shallow coves with accumulated sediment can leave a dock unusable for full-size boats even when the main lake is at normal pool.

During the Due Diligence Period

Home Inspection with Lake-Specific Focus

Standard home inspection applies at Lake Anna, but a lakefront-experienced inspector will additionally check the dock structure, boat lift mechanism, dock electrical (stray current in the water around the dock is a safety concern), and the condition of any riprap or shoreline stabilization. Confirm the inspector has specific lake home experience, not just general residential inspection credentials.

Septic Inspection and Capacity Review

All Lake Anna properties are on private septic. A full septic inspection — including a dye test on older systems — is essential. Properties in the RPA (Resource Protection Area) buffer zone adjacent to the water face additional restrictions on septic system repair and expansion. Confirm the system's age, type, and approved capacity relative to the number of bedrooms the property is marketed with. Septic systems that were sized for two-bedroom weekend use but are being sold as four-bedroom primary residences are a documented pattern at lake markets.

Water Quality Test for the Well

Virginia requires a water quality test as part of mortgage approval for properties on private wells. At minimum, test for coliform, E. coli, nitrates, and any additional parameters your lender or inspector recommends. Given the documented E. coli presence in parts of Lake Anna in summer 2024, testing the well water independently — not relying solely on the seller's representation — is prudent.

Verify Water Depth at the Dock

Get actual depth measurements at the end of the dock and at the cove entrance during the inspection period. Lake Anna's stable pool means depth at normal conditions is largely representative of year-round conditions, unlike drawdown lakes. But siltation in upper coves is real and can significantly reduce usable depth. A depth finder measurement during the inspection period takes 10 minutes and is definitive.

At Closing

Confirm that the Dominion Use Agreement documentation is included in the closing file and that Dominion has been notified of the ownership change. The Use Agreement is tied to the structure and property; the new owner needs to be on record with Dominion as the responsible party for ongoing compliance and annual fee payment. Some agents and title companies experienced in Lake Anna transactions handle this notification routinely; others do not. Ask explicitly whether it will be addressed at closing.

If the property is in a Louisa County shoreline-regulated area, confirm that any required building permits for the dock were obtained and closed out with inspections. Open building permits that were never finaled — a common occurrence with waterfront improvements done informally — can create lender issues and title complications.

Title insurance is essential at Lake Anna. Dominion's easements and the complex boundary between private property and Dominion's shoreline make a thorough title search non-optional.

The Team You Need

An effective Lake Anna buyer team includes a buyer's agent who regularly closes lake transactions and understands Dominion's Use Agreement system (not just general waterfront experience), a home inspector with lake home credentials who knows to check dock electrical and structure, a real estate attorney familiar with Dominion easements and Louisa County's shoreline ordinance, and a lender who has financed Lake Anna waterfront and is familiar with the appraisal complexity of a lake where the public/private split affects comparable selection.
