Lakes
What actually governs the community's biggest wet asset, and how to build a plan around it.
No general code sets a maintenance standard for HOA lakes; they're governed almost entirely by your governing documents, your state's dam safety rules if the lake has a dam or spillway, and local water quality authorities. Start by asking your state dam safety office whether your lake is a regulated dam, then document a maintenance plan a contractor can follow.
There is no lake code to look up
Most of the components in this course, roofs, elevators, sprinklers, have a code or trade standard that tells a board roughly how often to inspect them. A lake does not. There is no federal, state-model, or trade-body inspection interval written specifically for a residential lake the way there is for a fire alarm or a pool. What actually governs your lake is a stack of narrower rules: your own CC&Rs, the manufacturer specifications for any pump, aerator, or fountain installed in it, and whatever state or local rules apply to dams, water quality, and water bodies in your jurisdiction.
Find out if your lake is legally a dam
If your lake was created or is held back by an earthen embankment, dike, or spillway, it may meet your state's legal definition of a dam, and whether it does depends on the structure's height and how much water it can hold, figures set state by state. States that regulate dams typically classify them by hazard potential, how much damage a failure could cause, and tighten inspection intervals as that potential rises. A board cannot answer this by eyeballing the embankment or checking the reserve study. The only reliable way to find out is to contact your state's dam safety program directly and ask whether your lake's structure is regulated and what inspection interval applies.
Build a documented maintenance plan
Many HOA lakes do double duty: they're an amenity, and they also collect and slowly release stormwater runoff from streets, roofs, and parking lots in the community. If yours does, treat it the way the EPA treats any stormwater pond and give it a written plan, not just an annual walkthrough.
A documented operation and maintenance plan should include "Identification of the parties responsible for maintenance," "Maintenance schedules," "Inspection requirements," "Frequency of inspections," and "Identification of a funding source."

Put a version of that plan in front of your maintenance contractor and your insurer, and revisit it every time you change vendors.
Confirm who actually pays
Your CC&Rs assign who is responsible for the lake, not the reserve study. A reserve study only lists a component if it clears a specific four-part funding test, so a lake absent from the reserve study can still be squarely the association's job to maintain under the governing documents. Water quality, algae blooms, fish kills, and shoreline erosion aren't covered by any national maintenance code either. Get a qualified aquatic or lake management contractor under contract, and ask your state or local environmental agency what water quality rules, if any, apply to a privately owned lake in your community.
Check yourself
Answer before you read the explanation, recalling it is what makes it stick.
Your HOA lake has an earthen embankment and spillway. A director says it's just landscaping, not a dam. What should the board do to find out?
The HOA lake also collects and slowly releases stormwater runoff from the community. What should the board's maintenance plan for it include?
An owner argues the HOA doesn't have to maintain the lake because it isn't listed in the reserve study. Is that correct?

Whether your lake counts as a regulated dam, what inspection interval applies, and who is financially responsible for it vary by state, local rules, and your own governing documents.
