Attention Arvada Reservoir Boat Users

As you may have heard, bodies of water in the State of Colorado now face the threat of two invasive species: the Zebra mussel and its cousin the Quagga mussel. The introduction of these mussels to lakes and reservoirs permanently alter ecological systems. The mussels reproduce rapidly and out-compete native organisms for food sources, resulting in lake conditions which favor the growth of blue green algae, degrade sport fisheries, negatively impact the taste of municipal water supplies, and plug pipes leading to municipal water treatment plants.

Last year, the City of Arvada initiated a boat inspection program to help reduce the likelihood that the Arvada Reservoir would become infested with these mussels. This year we are expanding the program as follows:

  • Trailer-mounted boats will have a new quarantine period of 14 days. This program involves inspection of the boat and trailer, and the installation of a tag connecting the boat and the trailer demonstrating that the boat has not been launched on another reservoir. Boaters who use Arvada Reservoir exclusively will notice very little impact and in fact if your boat is tagged from last year you do not need to have it re-inspected.
  • Car top carry boats such as canoes, kayaks, and other small craft that are transported on the top of a vehicle will be inspected on the day of use. If clean and dry, they will be allowed to launch.
  • Wet (aquatic) bait is prohibited, as the water from which they originated may carry mussel larvae. This includes, but is not limited to, minnows, leeches, frogs, crayfish, and salamanders.

On Saturdays February 28, March 7, and 14, the City will offer a pre-season boat inspection program to assist you in preparing for the 2009 season. Park rangers will be at the Arvada City Hall parking lot, 8101 Ralston Road from 10 a.m. to 2 p.m. to inspect and tag your boat. Thereafter, the inspections will take place at the Arvada Reservoir.


Thank you in advance for helping to keep Arvada Reservoir free of Zebra and Quagga mussels. Please share this information with anyone you know that uses this wonderful resource. If you need further information, please call Tom at 720-898-7416.
