Ceiling & Roof Leak Water Damage Repair in Conroe, TX

Downstream of a reservoir that is expected. The level here reflects releases as well as rainfall, and releases are managed on the basis of what is happening upstream and what the reservoir has to hold. That can mean rising water on a clear day locally. Following release information alongside the weather gives a much better picture than the forecast alone, and it usually provides more warning than local rainfall would.

That handles what falls on your property, which is genuinely worth having. It has no effect on water arriving from a river or from a catchment upstream that has been developing quickly. In a county growing this fast, the runoff reaching a given point has changed within the lifetime of the houses receiving it, so historical experience of a site can understate current exposure. Lot drainage and watershed exposure are separate questions.

Sandy loam over clay is usually the reason. Water soaks down through the sandy layer, meets clay it cannot pass, and then travels sideways along that boundary, surfacing or collecting some distance from where it fell. A yard can look well drained while water is moving underground beneath it. Interception at the perimeter, rather than surface grading, is what addresses that pattern.
