The following protocols were instituted by the Westminster Water Quality Department:
All paddle craft must enter the park through the main gate. When you purchase your daily paddle pass ($15) at the gate house, staff notifies ranger staff to meet you at the spray station to spray your craft (paddle craft must be inflated prior to getting the spray if it is an inflatable).  You will be required to present your entry receipt to the ranger at the spray station.  Rangers will conduct the spray using hot water (no chemicals). There is no quarantine period for paddle craft unless it is on a trailer. Once sprayed, you will receive a wrist band, which indicates your paddle craft has met the ANS protocols and is clear to launch on the lake. Any person(s) utilizing paddle craft must wear valid wristband while recreating at Standley Lake.  
Only non-aquatic bait will be permitted for fishing. Aquatic bait (minnows, leeches, frogs, etc.) is NOT permitted at Standley Lake Regional Park.
Fishing is allowed only from sunrise to sunset. Night fishing is prohibited. 
Any trailered vessel must have a full decontamination, engine flush and meet the established quarantine period. Boat engines or motors need to be in working order and able to be started in order for inspection and engine flush to be conducted. Decontaminations will be done by appointment only prior to May 1.
Program quarantine periods will be as follows:  May 1-Sept. 30 = 35 days
This quarantine period is necessary due to data that has shown that veliger larvae can survive for approximately 30 days in the residual water of trailered watercraft. Colder average daily temperatures relate to the length of time Zebra or Quagga mussels may be able to live once the boat is out of the water. Even though boats are inspected and washed, the quarantine periods are an important part of the efforts to protect Standley Lake and also allow recreational boating. A clear, Westminster boat tag will be attached to the boat and trailer when you have been cleared or when you are leaving the lake for the day. If the tag is intact when you return, you will be allowed to launch your boat. Tags must be removed by Standley Lake staff only.
Boats that have been stored on site at Standley Lake during this off-season and are tagged, or boats that stop by Standley Lake and are inspected/tagged by March 25, 2018 will then have time to meet the quarantine period and will be cleared to launch by May 1. These boats will be clear-tagged to show that they have met the quarantine requirements and can launch onto Standley at the start of the 2018 boating season. If you would like to have your boat inspected and tagged prior to March 25, 2018, you may do so during normal operating winter hours, 9 a.m. to 4 p.m., at the Standley Lake Nature Center. The inspection and decontamination program is available only to boats using Standley Lake.  


  • Intact Clear (Westminster) Tags = Go. You may boat on Standley Lake
  • Red Tags = Stop. You must complete the inspection/cleaning/quarantine process before launching onto Standley Lake.
  • No Tag / Broken Tag = Stop. You must complete the inspection/cleaning/quarantine process before launching onto Standley Lake. 
  • Standley Lake does not accept any seals from other agencies.  
  • Boats that have been launched on another lake are required to go through the inspection, cleaning and quarantine (drying) process. 


Inspections and cleanings take approximately 35 to 45 minutes. The quarantine period is 35 days over the course of the boating season. Once boats meet the initial quarantine period, they will be allowed on Standley Lake with no delays each time they return, provided they have not been to another lake. The only time they have to be re-inspected or quarantined is when the tag on the boat has been disturbed or the boat has been on another lake. At this point it will be inspected, cleaned, re-tagged and quarantined for the appropriate amount of days (35) before it will be allowed on the lake. 

There are some boats that use Standley Lake that have bladder-water ballast systems. Those boats will require inspection and additional safeguards to ensure the ballast bladders are clean and do not have aquatic nuisance species larvae in them. If you own a boat with that type of system, please contact the staff at Standley Lake to learn about the requirements for your boat.

Recreational Boat Use Procedures:  
Only Standley Lake staff can remove tags! - Do NOT remove your own tag!
No watercraft of any type (tubes, paddle boards, kayaks, canoes, rafts, etc.) will be allowed to launch without being sprayed. Failure to do so will result in a citation and confiscation of vessel.
All boats and trailers must be CLEAN and DRY.
All drain plugs must be removed prior to boat transport that day.
All boats will be quarantined (tagged) for a certain number of days (35) before being allowed to launch in Standley Lake.
Boats that don’t require quarantining, i.e., roof top, non-trailerable, etc., will be thoroughly inspected and treated with a hot pressure wash (water only, no chemicals) by Standley Lake Regional Park staff prior to launch.
Other watercraft/equipment also requires inspection/washing/tagging/quarantine based on various conditions, such as history of use of the boat on other waters, time of year, broken tag, etc.
Staff may turn away any boat that does not meet these regulations. Boats that are contaminated will be confined for additional cleaning/decontamination and notification to State officials.
Violation of these regulations can result in fines and/or revocation of permit privileges.
You may request a “double-tag” for any reason. We highly suggest you ask for a “double-tag” if you are going to do any maintenance or waxing on your boat.
