"We strongly discourage any body contact with the water at this point"
David Casaletto, Executive Director, Ozarks Water Watch
The above quote is referring to Grand Lake, Oklahoma and was from the Grand River Dam Authority Corporate Communications Director Justin Alberty. Justin went on to say, "That means no swimming or any other activities that would bring you into contact with lake water." His statement was released on Friday, July 1st as the July 4th holiday weekend was just starting. Imagine the impact these words would have here in the Upper White River Basin! Along with these type of statements, warning signs (see picture below) were also posted around the lake.

The problem is blue green algae have been found in parts of Grand Lake. Blue green algae (BGA) can make people sick and can even occasionally be fatal. According to the Oklahoma Department of Environmental Quality (DEQ), BGA are microscopic organisms present in bodies of water. It can reproduce rapidly in the water with adequate amounts of sunlight and nutrients such as phosphorous and nitrogen. Any contact with BGA can be harmful. The toxins produced by BGA may cause a variety of reactions, most commonly, upper respiratory problems, eye irritation, vomiting, and diarrhea.  | | Blue Green Algae on Grand Lake |
The Oklahoma DEQ suggests avoiding any body contact with water where BGA is present - which includes swimming, water skiing, boating - and that a physician be called if you or someone you know comes in contact with the algae. Because children typically weigh less than adults, they are vulnerable to smaller quantities of the toxins which can trigger a more severe effect. 
BGA looks like thick pea soup or green, bluish, brownish or reddish-green paint. On shore, it can form a thick mat on the beach. If animals consume or inhale BGA it can lead to severe illness and even death. Click HERE for a BGA fact sheet.

So now that I have your attention, let me go back in time. I grew up in the Pittsburg, Kansas area. In southeast Kansas there is quite a bit of top soil and the rivers and streams for the most part have mud banks and bottoms with the occasional gravel bar. One of these rivers that I spent a fair amount of time at was the Neosho River. We would fish and swim and do all the fun things you do on a hot summer's day. I remember my dad telling me that during the heat of the summer the river would become stagnant and it probably was best not to swim. He called this the "dog days" of summer. I grew up to think the Neosho was a normal river and it is for southeast Kansas. I had no idea at the time how beautiful the streams are in the Ozarks!

In the above picture, taken sometime around 1985 on the banks of a southeast Kansas water body that may be the Neosho River, you see my daughters; Sarah in the green care bear shirt, Kristin on the ground, Angela is in the upper left hand corner and my legs are just visible in the upper right above the tackle box. I am sure my wife Diane is taking the picture. I want you to notice the dried mud banks. During a storm event, the rivers are swollen with sediment and nutrients. The Neosho River flows into Grand Lake.

In the above map, you can see the Neosho River Watershed (teal color) in the upper left extending north far into Kansas. You will also notice that parts of the Grand Lake watershed are in four different states. This means that four different groups of state agencies, all with different rules and regulations, are responsible for keeping the waters clean. And on top of that, Kansas and Missouri are in EPA Region 7 and Arkansas and Oklahoma are in EPA Region 6. To say the least, this makes things difficult! Last week I attended a water quality conference in Fayetteville, AR. While the conference dealt with a different watershed, there were many Oklahoma water quality experts in attendance. They told me the warning signs of this type of algae bloom on Grand Lake have been there for years but due to inaction this is the result. There are also watershed organizations such as the Grand Lake Watershed Alliance Foundation (formed in 2007) and the Elk River Watershed Improvement Association (formed in 2004) working to spearhead efforts to begin to turn things around in the Grand Lake basin. In the Upper White River Basin, we need to learn from this event. We cannot just say that we are glad it is them and not us but we must be proactive. In the Table Rock and Taneycomo Lakes watershed we are very fortunate that the Missouri Clean Water Commission in 2002 approved a phosphorous limit on point source discharges from wastewater treatment plants. This phosphorous limit was in response to a large algae bloom in the upper James River Arm of Table Rock Lake (see picture below).

The good news is that the lake responded quickly to the reduction in nutrients and we have not had a repeat of this algae outbreak. But we have to realize that we have not fixed the problem but only bought us some time. The huge increases in population in the Upper White River basin puts enormous pressure on our streams and lakes through nutrient loading from both point and nonpoint sources. We have picked the low hanging fruit by reducing nutrient loading from point sources and we MUST NOW deal with nonpoint sources of nutrients. These include failing septic systems, storm water runoff, land disturbance, animal operations, fertilizers spread on rural and urban areas, etc. In the Illinois River watershed in northwest Arkansas and Northeast Oklahoma, these issues have come to a head. Without going into a long history of past events, EPA Region 6 is now in the process of writing a TMDL (Total Daily Maximum Load) for the Illinois River watershed that will most likely mandate reductions in nonpoint source loading of nutrients in that watershed. This TMDL will have a far reaching impact, even nationwide, as up to now, nonpoint source reductions have for the most part been voluntary. I encourage everyone that can, to attend the 4-State Watershed Academy to to be held September 29th and 30th in West Siloam Springs, OK.
This academy will feature presentations that deal with TMDLs and what we face in all our watersheds with these nutrient issues. As of the writing of this newsletter, there are commitments from Missouri Congressman Long and Arkansas Congressman Womack and Missouri DNR Director Sara Parker-Pauley and Arkansas ADEQ Director Teresa Marks to attend and participate in the academy. Due to another large event being held in the area during this time, hotel rooms will be at a premium, so if you think you may attend, I encourage you to reserve your room now! All of us must become educated and involved. Only by all of us working together can we hope to protect and preserve our outstanding Ozark water quality.
