Green Mountain seals and receipts (blue or white) are no longer valid for pre-inspection anywhere in Colorado State Parks. These boaters can no longer use drop box/pre-inspection after hours.

On Aug. 18, 2017, as part of a state and federal initiative to monitor aquatic nuisance species (ANS) in the state, specialists with the U.S. Bureau of Reclamation first confirmed the presence of the veligers, initially through microscopic analysis followed by DNA testing. An independent laboratory contracted by Colorado Parks and Wildlife confirmed Reclamation's findings. It is unknown if the veligers were dead or alive at the time of detection.

(2) The traffic density including concentration of fishing vessels or any other vessels;
(3) The maneuverability of the vessel with special reference to stopping distance and turning ability in the prevailing conditions;
(4) At night the presence of background light such as from shore lights or from back scatter of its own lights;
(5) The state of wind, sea, and current, and the proximity of navigational hazards;
(6) The draft in relation to the available depth of water.
