As water conditions continue to improve … GRDA lakes ready to welcome visitors over July 4 holiday

Langley – Despite historic rainfalls and elevated lake levels in recent weeks, the Grand River Dam Authority is reporting that conditions on Grand Lake continue to improve, just ahead of the July 4th holiday.

“The lake is in good shape and we expect to see a lot of visitors enjoying the water over the holiday weekend,” said GRDA Corporate Communications Director Justin Alberty. “The water level is steadily returning to normal and the lakes are open for business.”

Alberty added that the latest projections from the United States Army Corps of Engineers showed that Grand Lake would only be about 3.5 feet above normal on July 4, with GRDA’s Lake Hudson at roughly 6.5 feet above normal for the weekend.

The Corps was also directing GRDA to close the last floodgate on Pensacola Dam’s east spillways on Thursday afternoon (July 2). With that gate closed, Alberty said the boat ramps located between the spillways (east of Disney) would be open for the weekend.

For those visiting the lake area near the dam, the GRDA Ecosystems and Education Center (420 Highway 28) in Langley will also be open throughout the holiday weekend, as a resource for those visiting the lake.

“It’s a great place to pick up information like lake maps, the GRDA lake guide or other materials that can help make a visit to the area more enjoyable,” said Alberty, adding that free tours of GRDA’s historic Pensacola Dam – which originate from the Ecosystems Center – will also be available all weekend.

Around the lake area, several fireworks displays are also scheduled during the weekend. Disney’s annual Cliff Elliott Memorial Fireworks Show is scheduled for Friday, July 3 at 9:30PM. The Monkey Island Fireworks Show is also Friday, as well as the City of Grove’s “Happy Birthday America” Celebration, from 6-10PM, with fireworks scheduled for 9PM.

Meanwhile, the Duck Creek Fireworks show, considered to be the largest in the state, takes place Saturday night, July 4, in the Duck Creek arm of Grand Lake. While the actual fireworks go off at 9:30PM, other activities in the area begin as early as 4PM. Further south, along the shores of GRDA’s Lake Hudson, the community of Salina will also have its fireworks display Saturday night at 10PM.

“Around the GRDA lakes area there will be plenty of places to enjoy fireworks displays both on and off the water,” said Alberty. “We just encourage everyone to use common sense, boat safe, smart and sober and enjoy the weekend on the lake.”

Finally, the GRDA Police Department reminds boaters that if they need immediate assistance on that water, they should contact 911. However, if they are on a boat with no cell phone access, they can also use Marine Band 16 to radio for help.

Remember, special Duck Creek boating rules …

GRDA Police remind lake visitors to boat safe, smart and sober during the holiday weekend

Boaters take to the waters of Grand Lake during a summer day in 2014. With the July 4 weekend right around the corner, this scene will be repeated as thousands of lake enthusiasts visit Grand Lake and Lake Hudson. If you are planning some time on the water, the GRDA Police want to remind you that boating safe, smart and sober is still the best way to have a safe, memorable outing.

Boaters take to the waters of Grand Lake during a summer day in 2014. With the July 4 weekend right around the corner, this scene will be repeated as thousands of lake enthusiasts visit Grand Lake and Lake Hudson. If you are planning some time on the water, the GRDA Police want to remind you that boating safe, smart and sober is still the best way to have a safe, memorable outing.

Langley – It is no secret that the Fourth of July holiday is also the most popular time for visitors to Grand and Hudson lakes in Northeast Oklahoma. Summer weather, fireworks displays, family gatherings and other holiday celebrations will draw thousands to the lakes for extended stays in conjunction with the 2015 holiday, which falls on a Saturday this year.

However, in the midst of all the celebrations, the Grand River Dam Authority Police Department wants to remind boaters to take a few moments to consider safety on the water. Remember, “boating safe, smart and sober” is still the very best way to create enjoyable, lasting memories of your time at the lake.

One very special message the GRDA Police share with Grand Lake visitors each Fourth of July is the reminder that special boating rules will be in effect for the Duck Creek arm of the lake. Those rules are as follows:

• All watercraft wider than 8.5 feet shall operate at “Idle” and avoid producing a wake at all times in Duck Creek. (If the vessel is wider than 8.5 feet, Duck Creek is no wake for the vessel at all times regardless of length).

• All watercraft longer than 30 feet shall operate at “Idle” and avoid producing a wake at all times in Duck Creek. (If the vessel is longer than 30 feet, Duck Creek is no wake for the vessel at all times regardless of width).

• All watercraft smaller than both measurements listed above may operate on plane not to exceed 30 mph in Duck Creek from official sunrise to official sunset.

• All watercraft must “Idle” and avoid producing a wake from official sunset to official sunrise (night time) in Duck Creek between May 1 and Oct 1. (No wake in Duck Creek for all vessels at night).

• All Watercraft must stay to the right of the center lane of buoys and at least 150 feet away from any dock, breakwater, structure, or shoreline.

• On the actual day of the Duck Creek Fireworks, all watercraft shall operate at “Idle” and avoid producing a wake at all times in Duck Creek (all day, all night).

• The area known as “The Turn” (area near Harbor’s View and Ugly John’s) is a no wake zone for all vessels at all times.

• Areas north of “The Turn” are No Skiing areas, and the vessel size restrictions mentioned above apply to this area as well.

Heavy rains across the region in the last several weeks led to high water inflows into the Grand River System and elevated lake levels. Though Grand and Hudson are both returning, slowly, to normal levels, both will still be above normal during the holiday weekend. Due to that, the GRDA Police Department continues to remind boaters to use extra caution on the water, especially if they plan on boating in unfamiliar areas of the lake.

Other tips to keep in mind if boating during times of elevated lake levels:

• Be mindful of your boat wake and proceed with caution in areas near structures. When lake levels are elevated boat wakes can cause damage to structures that are normally above the shoreline.

• Stay away from floodgates and spillways. There is a chance that floodgates could be open at both Pensacola Dam (Grand Lake) and Robert S. Kerr Dam (Lake Hudson) as you are boating. If that is the case, please observe the buoys designating the spillway areas and allow plenty of distance between those locations and your boat. Also, please use common sense and stay away from areas below floodgates where water is being released.

Finally, GRDA Police continues to stress the dangers of drinking and boating. According to the National Association of State Boating Law Administrators, alcohol use was the leading factor in 21% of recreational boater deaths in 2014.

“It’s just a bad idea,” said GRDA Assistant General Manager/Chief of Law Enforcement and Lake Operations Brian Edwards. “It can impair your judgment, your depth perception and overall ability to operate your vessel. Plus, it creates a dangerous situation not only for you but for your passengers and everyone else in the water around you.

Edwards added that GRDA’s goal is for everyone to enjoy a wonderful, safe outing on the water over the holiday, and boating safe, boating smart and boating sober makes that possible.

“Come have a great time on the water,” he added, “but play safe so you can come back again too.”

GRDA lakes will have a slow return to normal elevations

Floodgates at GRDA’s Robert S. Kerr Dam release water from flood-swollen Lake Hudson on Monday, June 1.

Floodgates at GRDA’s Robert S. Kerr Dam release water from flood-swollen Lake Hudson on Monday, June 1.

Despite the high lake levels, the Grand River Dam Authority is reminding boaters that lake-area businesses around the shores of Grand and Hudson are open and GRDA does expect the lake to be busy over the weekend and the days ahead.

“We simply want to stress common sense and caution as boaters visit the lakes during this time,” said GRDA Corporate Communications Director Justin Alberty.

Alberty added that the heavy inflows into the Grand River Watershed have slowed in the last few days, but a return to normal water levels may take weeks for both Grand and Hudson lakes.

“Because this flooding episode was so widespread, across several reservoirs in the region, it’s just going to take a while to get all the water downstream safely,” he said. “The good news is, lake levels are headed in the right direction, but it will take some time before they return to normal.”

Alberty said the United States Army Corps of Engineers, which controls floodgate operations and GRDA’s Pensacola and Robert S. Kerr Dams, is managing releases not only from the Grand River Watershed but from several flood-swollen lakes in Oklahoma.

“Most river systems in Oklahoma have experienced flooding and that includes the systems south of GRDA’s lakes which

GRDA Police work to remove floating debris from a buoy line in front of Robert S. Kerr Dam on Monday, June 1. If you are heading to the water this weekend, the GRDA Police remind you to watch out for floating debris, due to high lake levels, and stay well clear of areas near floodgates.

The GRDA Police Department does offers the following tips boaters should keep in mind if they plan to visit Grand or Hudson lakes during the next few weeks:

• Be mindful of your boat wake and proceed with caution in areas near structures. When lake levels are elevated boat wakes can cause damage to structures that are normally above the shoreline.

• Be aware of floating debris. Higher lake levels can mean more driftwood and debris floating in the water. Please be on the lookout as you are boating.

• Be mindful of the changing shoreline topography and the possibility of now-submerged structures. Things like stumps, picnic tables, retaining walls and other structures typically located along the shoreline may now be submerged due to the lake levels. Use extreme caution and avoid unfamiliar areas of the shoreline.

• Stay away from floodgates and spillways. There is a chance that floodgates could be open at both Pensacola Dam (Grand Lake) and Robert S. Kerr Dam (Lake Hudson) as you are boating. If that is the case, please observe the buoys designating the spillway areas and allow plenty of distance between those locations and your boat.

• Do not go into spillway areas below the dam. Please use common sense and stay away from areas below floodgates where water is being released. The swift water can be very dangerous and it is against the law to enter into floodwater discharge.

• If you need immediate assistance, the GRDA Police recommends you call 911. However, if you are on the boat with no cell phone access, you can use Marine Band 16 to radio for help.

• Finally, a good reminder for boating in all conditions: always wear your life jacket.
