Should Your Stormwater Pond Hold Water? Start with Its Intended Design
A stormwater pond may be intended to hold water permanently, temporarily, or in only a small part of the basin. Before asking someone to drain it, establish which design your property has and what water level is expected between storms. Compare current conditions with that documented baseline, not with a nearby pond that looks different.
Wet and dry describe different expectations
EPA's dry detention pond guidance describes basins that temporarily hold stormwater to reduce peak flows and allow some particles to settle. Unlike wet ponds, they do not have a large permanent pool, although small pools may be present near an inlet or outlet. That distinction matters: a little water in one designated area does not automatically mean a dry basin has failed.
A wet pond includes an intended permanent pool. EPA's wet pond guide also describes designs that combine a pool with additional temporary stormwater storage. The everyday word pond is therefore not a complete description of how a particular facility should behave. Ask for the name used on its plans and an explanation of the expected water pattern in ordinary language.
For an HOA board or commercial property manager in Middle Tennessee, the useful first question is not whether all standing water is bad. It is whether this water is where the plans expect it to be. Do not order a conversion from wet to dry, or the reverse, as though it were a routine landscaping preference.
Build a one-page pond identity sheet
Start a shared record with the property address, a map showing the basin, and the facility name or number used in existing paperwork. Add the date and title of the plan you found. If there are multiple basins, identify each separately rather than labeling every photograph the pond. A board member or replacement manager should be able to understand the record without having attended the original site visit.
Look for the approved drainage plans, any as-built drawings, the operation and maintenance manual, and earlier inspection reports. Ask the property owner or association's records contact for missing material. Record documents you have requested as well as documents received; an empty folder should not quietly become an assumption that no instructions exist.
Ask the reviewing professional to identify the intended normal water area on the map and explain where temporary storage occurs. Have them point out the relevant inlet, outlet, and access locations in terms your staff can recognize. Leave any unknown item labeled unconfirmed. This sheet is a communication aid, not a replacement for the design documents or a new engineering drawing.
Turn a water-level complaint into an answerable question
A message saying the pond is always full gives the reviewer little context. Instead, state the observation and its timing: which part is covered, when it was first noticed, and whether rain occurred before the observation. If practical from a safe location, take a second photograph from the same viewpoint later. Use an existing visible feature as a reference rather than sending someone into the basin to place a marker.
Include the earlier condition only when you have evidence for it. A dated photograph from last month is stronger than an uncertain recollection that the bank used to look different. Clearly label reports from residents or tenants as reports, and separate them from staff observations. Ask whether the reviewer needs additional information before arranging an inspection.
EPA's wet pond guide identifies unusually high or low pool levels as conditions to investigate and notes that an obstructed outlet can cause a high pool. It also cautions that low water is not automatically proof of a leak. These are reasons to compare against the design and investigate, not diagnoses an owner can make from a photograph. Avoid assigning a universal empty-by deadline to every pond.
Separate appearance requests from functional questions
Create two columns in your request for review. In the first, describe the concern about appearance: an exposed muddy edge, floating litter, or vegetation residents dislike. In the second, record questions about function: whether the observed level is expected, whether an outlet needs assessment, or whether the latest inspection left an unresolved issue. Some concerns may belong in both columns, but they should not be bundled into a vague request to fix the pond.
Ask the contractor to explain what a proposed task is intended to accomplish. Will it address a documented maintenance item, investigate an unknown condition, or merely change appearance? If the proposal includes excavation, altering an outlet, or changing the water level, ask who will review the design implications before work proceeds. Do not treat a photograph of a more attractive pond elsewhere as a specification for yours.
Keep observation separate from hands-on investigation. Do not enter water, pipes, or drainage structures to confirm a suspicion. Arrange appropriate professional access instead. A useful owner report can be made from available records and safe viewpoints; it does not require pulling debris from a submerged opening or operating unfamiliar hardware.
Choose the next decision, not an assumed repair
If the design is unknown, request a records review and site assessment first. If the documented water pattern appears unchanged but residents want an explanation, request a plain-language summary you can share. If a new condition has appeared, ask the reviewer to state the finding, the remaining uncertainty, and the recommended next action. These are different assignments and deserve different scopes.
For a paid assessment, agree on its deliverable before scheduling. Request an annotated map or photographs, the documents used, and a written distinction between confirmed findings and further investigation. If repair pricing will follow separately, make that explicit. This keeps an initial evaluation from being mistaken for either a complete repair contract or a guarantee that no issue exists.
Milliken Corporation lists retention and detention pond construction among its drainage services, along with other drainage and utility work. When discussing an existing basin, provide the records and describe the question you need answered. Ask the team to confirm the appropriate scope and any design-professional coordination rather than assuming that every pond concern needs construction.
Close the loop for the next property manager
EPA's stormwater maintenance resource recommends an operation and maintenance plan that identifies responsible parties, schedules, inspections, and funding. Use the property's applicable plan to organize ongoing work rather than substituting a generic internet checklist. Record who receives new concerns and who is authorized to arrange review.
After the assessment, update the identity sheet with the conclusion and link it to the full report. Record any follow-up appointment and the person handling it. When communicating with tenants or residents, explain what was established and what is still pending. The goal is a repeatable answer to the next water-level question, not a promise that the basin will always look the same.
Frequently asked questions
Does water in a dry detention basin always mean a blockage?
No. These basins temporarily store stormwater, and some designs include small pools. The location and persistence of water need to be compared with the particular design before assigning a cause.
Can our landscaper decide to drain the pond?
Do not authorize a water-level change based only on appearance. First establish the intended condition and have the appropriate professional review the proposed action and its scope.
What should a new HOA board request from the previous manager?
Request the drainage plans, maintenance manual, inspection and service records, outstanding recommendations, and relevant contact information. Ask which documents are missing and who was responsible for obtaining them.
