Oh hell, who am I kidding, everyone likes to say “I told you so” when proven to be correct.
All along, we have been strong proponents in raising not lowering the level of the lake in order to rid Lake Bistineau of salvinia . (See Blog Entries of Sept. 7th and Sept. 21st)
This theory of raising the lake always seemed to fall on deaf ears until Mother Nature decided to become a major player in the “Salvinia Game”. She dumped over 7 inches of rain into Southern Arkansas. The resulting run-off from these rains brought Lake Bistineau’s water level up 5-1/2 feet above normal. Water from the lake is now rushing over the lake’s spillway carrying the surface-floating salvinia with it.
In a matter of just days, Mother nature has removed more salvinia than the LWFD has done in 2 years. (see the video titled “Salvinia at the Spillway” by following this link … http://www.bayouducks.com/photo15.htm “)
Imagine how much of this plant could be removed if the LWFD worked through a program that utilized a series of raising and lowering the lake level.
We are not advocating raising the Lake level 5-1/2 feet each time but just 2-1/2 feet above normal. This continuous series of raising and lowering the lake level could be done 3 to 4 times a year ,“flushing” literally “tons” of salvinia over the spillway each time. This plan would not eradicate the plant, but in two years it would bring it down to a manageable level. If you have doubts, then just follow the link listed above.
Right now the LWFD needs to close the gates that are open and force all of the drain off from the flood waters over the spillway. The raised gates are simply draining water from the lake and leaving the salvinia behind.
