Historical Survey - Sediment Disruption

Name: Historical Survey - Sediment Disruption
Brand: Lake Pulse
Price: 900.00 USD
Availability: InStock

Where sediment has been disturbed on your lake, and how that has changed.

Checkout arrives with the store connection. Orders attach to the lake on your account.

Overview

Archived satellite imagery reconstructed into a sediment disruption record — where sediment plumes appear, how often, and whether the pattern has shifted over the years.

Available in high-resolution and low-resolution formats, in three tiers.

Frequently the most useful evidence in a wake sport dispute, because it covers the years before the argument started.

What problem does this solve for our lake?

Sediment disruption is contested for the same reason it is hard to measure: it is episodic, localised, and gone by the time anyone documents it. Plumes appear behind boats, after storms, in shallow bays — and disperse within hours.
Satellite archives catch what field observation cannot, because the satellite was passing overhead whether or not anyone was watching. The result is a spatial and temporal record: where disturbance appears, how frequently, and whether the pattern has changed as use has changed.
Resuspended sediment matters beyond aesthetics. It releases phosphorus into the water column, reduces light for native plants, and buries habitat. A pattern that overlaps your shallow bays and your treatment history is worth knowing about.

What's included?

Historical sediment disruption reconstruction from archived satellite imagery
Spatial mapping of where disturbance appears and how frequently
Change analysis across the covered period
Three tiers available, in high-resolution and low-resolution formats
Delivered as an interpreted report, not raw imagery
Results loaded into your lake's account

What's not included

Field sampling or laboratory chemistry. Satellite observation infers conditions from reflectance; it does not measure water.
Detection of anything below the surface. This is a surface-optical method.
Toxin measurement or species identification
Guaranteed coverage on any given date. Cloud cover and satellite revisit intervals decide what imagery exists.
Regulatory or compliance determinations

Requirements

Your lake's location and boundary
A lake of about 25 acres or more. Smaller lakes, narrow arms, and coves can fall below the image resolution.
The time period you want covered, and the question behind it
Realistic expectations about cloud gaps. Some dates simply have no usable imagery, and no amount of processing recovers them.
A Plus, Lake Admin, or PRO subscription to have results loaded into your Lake Pulse account
Contact the Lake Pulse Boathouse if you have questions.

What you get back

Results

A mapped record of where sediment disturbance occurs on your lake
Frequency and change over time, covering years before anyone was watching
Evidence that predates the current dispute, which is what makes it persuasive
Spatial context for shoreline management, wake policy, and habitat work
Results load into your lake's Data Library in the Lake Pulse Portal
Data can be charted in the Analytics Hub, used to trigger alerts, or shared across your lake community
Results are found in your lake's portal, accessible only to Plus, Lake Admin, and PRO subscription tiers

Pro tips

This is the wake sport evidence. Its strength is that it covers years before anyone had an opinion to defend.
Overlay it on your depth data. Sediment disruption is a function of depth, and the two together explain far more than either alone.
Distinguish storm plumes from recreational ones. Timing against weather records usually separates them cleanly.
Where plumes recur, look at the sediment phosphorus. Resuspension is an internal loading mechanism, not just a clarity problem.
Agree with both sides that this is the evidence before it is produced. That is what makes the result stick.

About these results

Every image shows the date it was captured. Satellite products are derived from reflected light recorded as a satellite passes over your lake. Values are relative indices, not laboratory concentrations, and cannot identify an organism, a toxin, or a pollutant. Cloud, haze, sun glint, shallow water, and shoreline effects can distort or hide the signal, and small lakes, narrow arms, and coves may fall below the image resolution. Conditions can change within hours of a pass. The absence of a detected bloom does not mean the water is safe. Results can help you make decisions about safe swimming and water use, but no result is definitive for every place and time. It is always good practice to check posted signs and your state or local health authorities.
