Hydrology Data & Navigation Disclaimer

1. Automated Sensor Telemetry & Potential Inaccuracies

The water levels, pool elevations, discharge rates, and water temperatures presented across LakeWatchers are collected from automated recording stations maintained by federal, state, and regional agencies, including:

• U.S. Army Corps of Engineers (USACE) CWMS networks
• U.S. Geological Survey (USGS) National Water Information System
• National Oceanic and Atmospheric Administration (NOAA) / National Weather Service (NWS)
• Regional River Authorities (LCRA, GRDA, TVA, BRA, SRA, etc.)

These automated gages operate in remote outdoor environments and are subject to physical phenomena that can cause data to be delayed, missing, uncalibrated, or erroneous:

• Transmission Latency & Satellite Outages: Telemetry modems transmit readings on periodic cycles (often hourly or every 3 hours). Flash flood inflows or emergency dam gate openings can alter water elevations well before gages update.
• Sensor Drift & Biofouling: Temperature thermistors and pressure transducers can accumulate silt, algae, mineral encrustation, or debris that temporarily skews readings.
• Power Outages & Equipment Maintenance: Severe thunderstorms, freezing conditions, or scheduled maintenance can take gages offline for hours or days.

Data presented on this website is provisional and has not undergone post-season quality assurance reviews by governing hydrologists.

2. Not an Official Aid to Navigation or Emergency Warning System

LakeWatchers is strictly an informational and recreational trip-planning tool.

• Not a Nautical Chart: This website does not publish certified navigation charts and does not replace official NOAA nautical charts, US Coast Guard aids to navigation, or official navigation buoys.
• Not a Flood Warning Service: For flood warnings, evacuation notices, or emergency spillway releases, always defer to your county emergency management agency, the National Weather Service, and local law enforcement.
• Captain's Prudent Seamanship: The operator of any watercraft bears sole legal and operational responsibility for the safety of their vessel, crew, and passengers. Vessel operators must always maintain a proper lookout, monitor marine depth sounders, proceed at a safe speed, and carry USCG-approved personal flotation devices (PFDs).

3. Submerged Hazards, Low Water Shoals & Shifting Sandbars

Lakes and reservoirs are dynamic man-made systems where lake bottoms and shorelines shift constantly:

• Falling Water Levels: When lake elevation recedes below conservation pool, submerged hazards—such as limestone ledges, rock islands (e.g., Sometimes Island on Lake Travis), tree stumps, and pipeline crossings—can sit inches below the surface in areas that were safe deep water weeks prior.
• Flooding & Floating Debris: High water events wash whole tree trunks, logs, and runaway dock floats into the main channels, creating deadly collision hazards at planing speeds.
• Shifting Sandbars: River and creek inflow points (such as the Washita and Red River deltas on Lake Texoma) continuously deposit sediment, reshaping underwater sandbars after every major rain.

4. Boat Ramp Usability & Park Conditions

While LakeWatchers tracks public boat ramp availability and normal operating elevations, actual ramp conditions vary based on on-the-ground factors:

• Ramps may be closed by local park rangers for dock repair, silt removal, or holiday overcrowding without immediate notice.
• Low water levels can cause the end of the concrete ramp slab to terminate in soft mud or a steep drop-off, risking trailer axle damage or vehicle submersion.
• Always inspect ramps on foot before backing your trailer down.

5. Fishing Regulations & Public Health Advisories

Information regarding fish species, seasonal patterns, and creel limits is provided for general angling enjoyment. Regulations change frequently:

• Always verify current slot limits, daily bag limits, and licensing requirements with the state wildlife department (e.g., Texas Parks & Wildlife, Oklahoma Department of Wildlife Conservation).
• Check state health department water advisories regarding toxic blue-green algae blooms (cyanobacteria), bacteria levels at public beaches, or fish consumption advisories.

6. Limitation of Liability & "As-Is" Provision

TO THE FULLEST EXTENT PERMITTED BY LAW, LAKEWATCHERS AND ITS OPERATORS PROVIDE ALL CONTENT, DATA, AND SERVICES ON AN "AS-IS" AND "AS-AVAILABLE" BASIS WITHOUT WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED.

LAKEWATCHERS EXPRESSLY DISCLAIMS ANY WARRANTY OF ACCURACY, COMPLETENESS, TIMELINESS, RELIABILITY, OR FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT SHALL LAKEWATCHERS, ITS CREATORS, OR CONTRIBUTORS BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES (INCLUDING, WITHOUT LIMITATION, VESSEL DAMAGE, TOWING COSTS, PERSONAL INJURY, LOSS OF LIFE, OR PROPERTY LOSS) ARISING FROM THE USE OF OR INABILITY TO USE DATA FROM THIS WEBSITE.

7. Notice a Sensor Discrepancy or Broken Ramp?

We take data accuracy seriously and appreciate our community of boaters, anglers, and lakeside residents who keep us informed of field conditions. If you notice a gage that appears frozen, an unlisted submerged hazard, or a ramp that is closed, please let us know immediately:
