Water Quality Report Cards
The Watershed Monitoring Section (WMS) manages two statewide water
quality monitoring programs, the Status Network and the Trend Network.
Each network answers questions about the conditions of Florida’s surface
waters (includes rivers, streams, canals, and lakes) and groundwater sites
(includes unconfined and confined aquifers and two spring vents). The
department uses data from both networks to develop protection and
WMS developed Status and Trend report cards into interactive map tools
that present water quality results to a variety of users. Links to the
report cards are provided below and to the right under “Water Quality
Report Cards”. Additional links to detailed reports regarding the data are
provided under “Annual Status Network Statewide Reports”.
The Status Network gives an annual snapshot of statewide water conditions.
The department uses field and laboratory results to calculate the portion of
waters meeting water quality standards. This network is not designed to answer
questions about specific waterbodies.
Trend Report Card
What is a Trend?
Trends represent change over time. The Trend Network tracks
long-term changes in water quality at fixed surface and ground water
sites. Examining water quality trends helps DEP determine if waterbody
conditions are staying the same, improving or declining. Trends can help
the department evaluate the effectiveness of its rules and water policies.
What do "increasing" or "decreasing" trends mean?

For example, within surface waters, increasing trends in dissolved
oxygen indicate an improved water quality condition (i.e. higher levels of
oxygen support increased biodiversity in aquatic communities). In
contrast, increasing trends of fecal coliforms in either surface or ground
water may indicate impacts from human activities.
For example, within ground water wells, an increasing trend in the
depth before reaching the water table generally indicates a decline in the
availability of the ground water resource. An indication of no trend for
pH in ground water may indicate more stable conditions versus an upward
trend of pH indicating conditions of unfavorable change.
