More Water Headed to John Martin Reservoir

Boaters and recreationists at John Martin Reservoir and John Martin State Park will have even more to love this season. This week, Colorado Parks and Wildlife will start moving 3,000 acre feet of water into the reservoir. "This is really exciting news and we are thrilled to be able to provide additional water this year," said Brett Ackerman, Deputy Regional Manager for Colorado Parks and Wildlife. "Years of drought have really taken a toll on John Martin Reservoir and protecting this exceptional fishery has been tough at times. This will really help out a lot." The additional water will increase the permanent pool at John Martin Reservoir to approximately 4,000 acre feet resulting in a safety net for the fishery, as well as more room on the water for boating, water skiing and angling. "John Martin Reservoir State Park has always had a lot to offer, but this year it will be even better," said Park Manager, Dan Kirmer. "Be sure you take the time to come check it out."

De-winterize Your Boat

Before heading out on the water make sure that you de-winterize your boat properly by following these steps:

  • First, drain out any water that may have found its way into your boat during the winter season. This helps avoid the accumulation of mold, rust, and any potential damage to components as temperatures rise.

  • With water muffs properly installed and working, start your boat at home to make sure it runs.  Be careful to keep the water flowing and not let it run long or overheating may result.

  • Check the battery to see if it can still hold a charge after the cold winter months. This can be done by taking a conventional car battery charger and checking if the battery holds 100 percent of the charge that it is given. If the battery has a full charge and the motor still won't turn on, replace any fuses that may have broken during the winter.

  • Check fuel lines for cracks/leaks or signs of rodents chewing on them, make sure hoses are connected, check fittings and connections to make sure they are tight, make sure plugs are in good shape and installed before heading out on the water.

  • Sign up for a boating safety class. CPW hosts nearly 100 classes throughout the state from April - September, not to mention the online options for boaters over 15.  Call (303) 291-7575 for class date and times.

  • Check that all boating safety equipment is still serviceable. Boat safety items are required and include personal flotation devices, a sound making device, fire extinguisher, navigation lights, and 2015 boat registration with visible CL numbers.

  • When you do get on the water for the first time, keep an eye on the temperature of your engine as sometimes after sitting in winter storage water pump impellers can fail and lead to a costly and potentially dangerous engine overheat. 

  • There is no substitute for the professional advice of a local boat service center.  If there are any concerns about the condition of a boat or ability to be functional out on the water for your first outing, call your local boat factory authorized center for professional advice.
