GRDA joins with other utilities in sharing “Pokémon Go” safety message

Vinita – While the “Pokémon Go” game continues to capture the interest of people all across the country, the Grand River Dam Authority is joining with other electric utilities in offering a simple safety reminder.

“We just want to remind people to stay clear of substations, generating facilities, power lines and any other areas where fencing and signage are in place to keep you safe and separated from the potential dangers of high voltage electricity, high waters or other hazards,” said GRDA Corporate Communications Director Justin Alberty. “Good luck catching them all, but just stay safe and aware of your surroundings as you do it.”

According to Wikipedia, “Pokémon Go” is a location-based augmented reality mobile game that allows players to capture, battle, and train virtual creatures, called Pokémon. By utilizing both GPS and cameras on mobile devices, these creatures appear as if they were in the real world. However, in the real world, players need to be aware of their surroundings.

Alberty said his organization has not had any issues with “Pokémon Go” players at its facilities but simply wanted to join utilities across the nation in sharing this message as a precaution.

Headquartered in Vinita, GRDA is Oklahoma’s state-owned electric utility; fully funded by revenues from electric and water sales instead of taxes. Each day, GRDA strives to be an “Oklahoma agency of excellence” by focusing on the 5 E’s: electricity, economic development, environmental stewardship, employees and efficiency.

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 ft., 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 (Sunday, July 3, 2016), 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.

The Woodard Hollow rules are as follows:

• All watercraft wider than 8.5 feet shall operate at “idle” and avoid producing a wake at all times in Woodard Hollow. If the vessel is wider than 8.5 feet, Woodard Hollow 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 Woodard Hollow. If the vessel is longer than 30 feet, Woodard Hollow is a 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 Woodard Hollow from official sunrise to official sunset.

• All watercraft must stay at least 150 feet away from any dock, breakwater, structure, or shoreline at any speed above “idle”.

While these are special rules for specific areas of Grand Lake, the GRDA Police reminds lake visitors that following lake rules and proper boating practices on all areas of the water is the best way to ensure a safe outing. What follows is a simple guide to some of the frequently asked questions concerning lake rules.

• Boats must not operate within 200 feet of any GRDA dam or no closer than 500 feet during generation.

• Boats, including personal watercraft (PWCs) must not operate within 50 feet of another vessel when running at speeds over 10 miles per hour (provided this prohibition shall not apply to vessels operating in sanctioned events).

• The nighttime speed limit on GRDA lakes is 25 miles per hour.

• Wake jumping is prohibited in any cove, creek or hollow.

• Water skiing, jet skiing and similar activities are permitted only during daylight hours and are prohibited upstream from above Twin Bridges, in Elm Creek, east of Grove. A boat towing a skier must have a person (at least 8 years old) in position to observe that skier, unless a rear view mirror has been installed for boat operator observation of skier.

Finally, GRDA Police continues to stress the dangers of drinking and boating. According to the United States Coast Guard’s most recent statistics on recreational boating (2015), alcohol use remains the leading contributing factor in boating accidents. Nationwide in 2015, there were 260 accidents, 228 injuries and 91 deaths as a result of drinking and boating.

“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.”

GRDA officers will be continuing the “I Got Caught” life jacket campaign during the July 4 holiday, on GRDA lakes and the Illinois River. As part of the program, free t-shirts are given to those boaters who are “caught” wearing their life jackets on GRDA waters.

Finally, if you are on the water and 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.

GRDA reassures the public that Grand Lake State Park swim beach is open

The Grand River Dam Authority is reassuring the public that the swim beach at Grand Lake State Park is open.

Recently a story was shared among social media sites that the swim beach at Grand Lake State Park in Bernice was closed due to bacteria presence in the waters. That was the case in 2014 due to the presence of E.Coli in the water. However, the Authority’s most recent sampling of the water shows all levels are in good shape now for swimmers.

“Public safety is our top priority,” said Melanie Earl, GRDA Assistant Superintendent of Media Services. ”We constantly monitor the water quality of the bodies of water under GRDA’s jurisdiction, and work diligently to inform the public anytime there is a concern of safety.”

Using genetic monitoring techniques (Microbial Source Tracking), GRDA’s Water Quality Research Lab found no fecal contamination (including no detection of human sources, which have the most potential to cause illness) in the water samples taken at Grand Lake State Park last month. The site will be tested again next week.

“GRDA’s Water Lab works daily monitoring the waters of Grand and Hudson Lakes, and there currently are no areas of concern in regards to public safety. However, like you would any time you visit the water, we just ask you to use common sense and follow safe swimming practices,” said Earl

If you do plan on swimming soon in area lakes or rivers, GRDA does want to pass along these tips from the Oklahoma Department of Environmental Quality (ODEQ). They are good to keep in mind any time you visit the water:

• Hold nose or wear nose plugs when jumping in the water.
• Wash open skin cuts and scrapes with clean soap and water immediately after swimming.
• Avoid swallowing water when swimming.
• Wear ear plugs to prevent ear infections.
• Wear swim goggles or masks to prevent eye infections.
• Avoid swimming near storm drains (pipes that drain polluted water from streets).
• Take children to restroom frequently/use swim diapers on infants.
• Also, after swimming, always remember to wash hands with soap and water for a full 20 seconds before preparing or eating food.

 

GRDA Police shares information, tips to help prevent the “station wagon” effect

Virtually all boating-related carbon monoxide (CO) poisoning incidents are preventable and that is why the Grand River Dam Authority Police Department is educating boaters on the “station wagon effect.” Good information and the right precautions can lead to safe, enjoyable outings.

Virtually all boating-related carbon monoxide (CO) poisoning incidents are preventable and that is why the Grand River Dam Authority Police Department is educating boaters on the “station wagon effect.” Good information and the right precautions can lead to safe, enjoyable outings.

“Virtually all CO poisonings are preventable.”

With boating season rapidly approaching, the Grand River Dam Authority Police Department is once again sharing information about carbon monoxide (CO), the “station wagon” effect and the possible dangers it can present to boaters.

“It is certainly something boaters need to be aware of,” said GRDA Chief of Law Enforcement/Lake Operations Brian Edwards. “The station wagon effect is essentially when fumes from a boat’s exhaust travel back into the boat or accumulate in an area near the boat where swimmers may be in the water.”

According to the Center for Disease Control and Prevention, CO can build up near the rear swim deck or water platform of larger boats equipped with generators that vent towards the rear. CO that builds up in the air space below the stern deck or around the swim deck can prove deadly, within a few seconds of exposure. Boats traveling at slow speeds, or idling in the water, can cause CO to build up in the cabin, cockpit, bridge, aft deck or even open areas of the boat. Wind blowing in from the back of the boat can also increase the chances of a CO buildup. Boats operating at a high bow angle, or boats that are improperly or heavily loaded, or boats with an opening that draws in exhaust, can also lead to CO buildup.

“However, the good news is that virtually all CO poisonings are preventable,” said Edwards, “but it’s important to know the facts so that you can protect yourself and your passengers. Then you can go enjoy your time on the water.”

To help educate boaters, GRDA is sharing the following information:

  • Install approved, battery operated CO detectors in each accommodation area of your boat. Test them before each trip out.
  • Properly install and maintain all fuel-burning engines and appliances on your boat.
  • Have your boat’s engine and exhaust systems maintained and inspected on a regular basis by experienced and trained mechanics.
  • Even in inclement weather, keep forward facing hatches open to allow fresh air to circulate in accommodation spaces. When possible, operate the boat so that prevailing winds will help dissipate exhaust.
  • Never swim and play in areas where engines vent their exhaust
  • Watch children closely when they play on rear swim decks or water platforms
  • Never block exhaust outlets. Blocking outlets can cause CO to build up in the cabin and cockpit areas, even when hatches, windows, portholes and doors are closed.
  • Dock, beach or anchor your boat at least 20 feet from the nearest boat that is a running a generator or engine. Exhaust from a nearby vessel can send CO into the cabin or cockpit of a boat.

It is also important to educate all your boat passengers about the following signs and symptoms of CO poisoning:

  • Headache
  • Confusion
  • Fatigue
  • Seizures
  • Dizziness or loss of consciousness
  • Nausea

Remember, CO cannot be seen or smelled. If anyone has these symptoms, move them to fresh air immediately and investigate the cause and take corrective action. Seek medical attention if necessary.

 “Taking these precautions and educating yourself on the facts of carbon monoxide and boating can go a long way in helping to keep boaters safe,” said Edwards. He added that the public can also find even more information about CO and boating on the United States Coast Guard’s boating information site at http://www.uscgboating.org/recreational-boaters/carbon-monoxide.php.

Also, visit the Centers for Disease Control and Prevention website http://www.cdc.gov/co/boating.htm for more information.

Governor signs Senate Bill 1388 … OSRC, GRDA merger to be finalized

Grand River Dam Authority Project/Research Director Rich Zamor, Ph.D., works inside the GRDA Ecosystems Water Quality Research Laboratory in Langley, Oklahoma. With the merger between GRDA and the Oklahoma Scenic Rivers Commission (OSRC) effective on July 1, GRDA’s stewardship mission for the waters of the Grand River System will also expand to the Illinois River in Northeast Oklahoma.

Grand River Dam Authority Project/Research Director Rich Zamor, Ph.D., works inside the GRDA Ecosystems Water Quality Research Laboratory in Langley, Oklahoma. With the merger between GRDA and the Oklahoma Scenic Rivers Commission (OSRC) effective on July 1, GRDA’s stewardship mission for the waters of the Grand River System will also expand to the Illinois River in Northeast Oklahoma.

Vinita – The Grand River Dam Authority is viewing its merger with the Oklahoma Scenic Rivers Commission (OSRC) as an opportunity to expand on the important work OSRC has advanced, while also continuing its own stewardship responsibilities in Oklahoma.

On Wednesday, May 11, Oklahoma Governor Mary Fallin signed Senate Bill 1388 into law. That bill calls for GRDA to assume the duties and responsibilities of OSRC on July 1, 2016. It also gives GRDA the power to set a new fee structure for recreational use, both along the Illinois River and in the spillway area below Pensacola Dam.

The OSRC was established by the legislature in 1977 to protect, enhance and preserve the Illinois River and its tributaries, Barren Fork Creek and Flint Creek. However, the agency — which receives roughly half of its funding from state appropriations — has faced many budget cuts in recent years, making it difficult for it to complete its mission. GRDA, a non-appropriated state agency — primarily funded by revenues from the sale of electricity — will absorb OSRC’s operations, employees and assets, as well as the stewardship mission.

“The Oklahoma Scenic Rivers Commission has been dying a slow death of a thousand cuts,” said OSRC Administrator Ed Fite. “The OSRC was once afloat, renowned as the most-efficient environmental agency of state government, but in recent years has barely been treading water.”

While the legislation ends appropriations for the OSRC and shifts those costs to GRDA, the mission of the OSRC will continue, said GRDA Chief Executive Officer Dan Sullivan.

“This merger allows the important work of caring for the scenic rivers to go on,” said Sullivan. “GRDA’s stewardship responsibilities for the Grand River system have always been similar and we feel like combining the experience and expertise of both OSRC and GRDA can only benefit all of these waters.”

Sullivan also noted that Fite’s 30-plus years of experience in Oklahoma water quality issues will be a great benefit to the GRDA Ecosystems Management Department.

“This merger will give him the opportunity and support to focus on water quality issues, instead of other budgetary or administrative issues,” said Sullivan. “We’re pleased he will continue as a member of the GRDA team.”

For Fite, that means continuing on with the cause that first launched the OSRC nearly four decades ago.

“Preservation and protection of scenic rivers is a cause that has no end point,” he said. “There is no point at which Oklahomans may say our work is finished.”

While some aspects of the merger may move slowly, including any new fee structures, Sullivan said by the July 1 effective date, GRDA will be ready to fully assume its new responsibilities along the Illinois River.

“We look forward to welcoming our new team members and continuing our efforts to care for these important Oklahoma natural resources,” said Sullivan.

Headquartered in Vinita, GRDA is Oklahoma’s state-owned electric utility; fully funded by revenues from electric and water sales instead of taxes. Each day, GRDA strives to be an “Oklahoma agency of excellence” by focusing on the 5 E’s: electricity, economic development, environmental stewardship, employees and efficiency.

 Since 2010, it has operated a state-of-the-art water quality research laboratory, inside its Ecosystems and Education Center in Langley. Today, the GRDA Ecosystems Management Department continues to work with the public, other state and federal resource agencies, as well as agencies across a four-state area, to preserve and protect the waters of the Grand River watershed.

GRDA offer not entertained by NE Electric Trustee Board

Vinita – An offer by the Grand River Dam Authority, which could continue its longstanding partnership with Northeast Oklahoma Electric Cooperative, was not entertained by the cooperative’s board of trustees.

GRDA Board Chairman Ed Townsend, Director Pete Churchwell and Chief Executive Officer Dan Sullivan were prepared to make the offer during a meeting of the trustees on Thursday, May 12, in Vinita. Though GRDA has continuously supplied the cooperative’s wholesale electricity since 1946, Northeast trustees voted to pass on the GRDA deal before they were presented with the details.

GRDA intended to offer Northeast $8.2 million cash upon approval of the agreement to purchase the cooperative’s transmission lines, radial lines and electric substation transformers, while also agreeing to serve all of Northeast’s current delivery points. GRDA would assume responsibility for the transmission assets and make an estimated investment of $15-$20 million to upgrade the transmission system. According to Sullivan, GRDA also offered its “most competitive rate” which would have saved the cooperative approximately $700 thousand annually.

“This is a 15-year deal that would give Northeast one service provider while also giving them access to the best energy costs from the Southwest Power Pool market,” said Sullivan. “It would also give them access to our diverse generation portfolio going forward, as well as continue the synergies between our organizations that have helped boost economic development and water quality in the Grand Lake area as part of a relationship that goes back 70 years.”

Former Oklahoma State Senator Rick Littlefield, who owns a business on Grand Lake, said he was disappointed by the news.

“As a Northeast member, I am deeply disappointed that a decision of this magnitude, which could adversely impact the Grand Lake area and cooperative members, was made without giving the membership a chance to provide input first,” said Littlefield.

At the meeting, Northeast trustees did advise the GRDA group that it would entertain an offer to serve half of the cooperative’s system.  

“We’re certainly disappointed that they did not entertain what GRDA feels is a very beneficial offer for their membership,” said Townsend. “However, we do appreciate the opportunity to explore serving half of their load and we will put together an offer to do that, in hopes of continuing this partnership that has benefited both organizations, their members and the Grand Lake region since the 1940s.”

 

Has your dock’s electric system been inspected?

As the weather heats up and our minds return to summer days spent dockside, the Grand River Dam Authority wants to remind dock owners to have their dock’s electric systems inspected on a regular basis.

As the weather heats up and our minds return to summer days spent dockside, the Grand River Dam Authority wants to remind dock owners to have their dock’s electric systems inspected on a regular basis.

Langley – With warmer weather, the end of the school year and the approach of summer all upon us, many people are not only spending more time in the water but also more time on their docks. With that in mind, the Grand River Dam Authority wants to remind all dock owners of the importance of maintaining compliance with dock electrical systems to ensure they are in proper working order.

The unfortunate truth is that a faulty dock electric system can be very dangerous, and may even prove fatal, for those in the water near the docks or those in contact with the dock. System defects can cause electric current to be discharged into the water or the metal components of the dock. That is why GRDA-issued dock permits require you to have your dock inspected by a licensed professional electrician.

Those inspections cover many areas of the dock, including proper grounding, conduit, breakers, wiring, dock receptacles, dock metal works and electrical service boxes.

“We can’t stress enough just how important it is to have your dock’s electric system inspected

The conduit, the grounding rod, the outlets and all features of a dock’s electric system should be inspected on a regular basis, by a Oklahoma licensed electrical contractor.

and in proper working order,” said GRDA Corporate Communications Director Justin Alberty. “Just as you inspect your boat and get it ready for the boating season, you should do the same thing with your dock’s electric system. Please take that precaution if you plan on spending time on your dock this summer.”

GRDA’s application for dock permits requires any dock wired for electricity to have a completed electrical certification form signed by an Oklahoma Licensed Electrical contractor before a final permit will be approved. Dock standards also require docks to have an electrical disconnect clearly identified and located above the high water mark. Also, any residential dock that has electrical service must adhere to the regulations set forth in the National Electric Code. Finally, any docks constructed or modified, relocated or transferred, are required to provide GRDA with a certificate signed by an Oklahoma licensed electric contractor, showing compliance with all laws, regulations and codes regarding electrical systems and wiring.

“There are standards in place for new and modified docks and transfers,” said Alberty. “However, all dock owners should have a regular inspection due to the simple wear and tear and weathering that occurs over the years.”

“These are tremendous assets for Oklahoma,” said Sullivan. “For GRDA, the waterway and port provided the only economical way to transport this turbine to Oklahoma.”

The Tulsa Port of Catoosa is one of the largest and most-inland ports in the country.

“The waterway is an integral part of the economy and transportation network for our region,” said Bob Portiss, Port Director, Tulsa Port of Catoosa. “We are proud that the MKARNS and the capabilities of the Port of Catoosa were so beneficial to bringing this oversize cargo to our friends at GRDA.”

GRDA to drop Holway Reservoir for routine inspection

Salina – In order to complete a mandatory inspection and collect important data along the canal and fore bay structure, as well as the penstocks and reservoir rim, the Grand River Dam Authority is informing the public that a drawdown of the W.R. Holway Reservoir will begin February 12.

GRDA is informing the public that it will draw down the elevation of the reservoir in mid-February to allow the Federal Energy Regulatory Commission (FERC) to complete a mandatory inspection.

According to GRDA Corporate Communications Director Justin Alberty, GRDA will lower the elevation of the reservoir to expose these areas and facilitate the inspection by the Federal Energy Regulatory Commission (FERC). FERC grants GRDA a license to operate the Salina Pumped Storage Project (SPSP) and this inspection is being done as part of those license requirements, said Alberty.

“This is a routine inspection which is required every five years but we are also collecting data to aid us in a repair project next year,” said Alberty. “We want the public to be aware because the level of the reservoir will be down about 42 feet below its normal operating level.”

Alberty said GRDA expects to begin refilling the reservoir by the second week of March.

Located east of Salina, Oklahoma, the Holway Reservoir is the upper reservoir attached to GRDA’s SPSP. This unique hydroelectric facility (the only one of its kind in Oklahoma), can pump water out of the Saline Creek arm of Lake Hudson and up the hillside into the upper reservoir. Then, when power generation is needed, the water is released back through the six turbine-generators in the powerhouse to create hydroelectricity. Holway Reservoir was created with the construction of the SPSP in 1968.

Headquartered in Vinita, GRDA is Oklahoma’s state-owned electric utility; fully funded by revenues from electric and water sales instead of taxes. Each day, GRDA strives to be an “Oklahoma agency of excellence” by focusing on the 5 E’s: electricity, economic development, environmental stewardship, employees and efficiency.
