Invasive Spotlight:
Creeping Jenny Moneywort

(Lysimachia nummularia)
Creeping Jenny Moneywort is a non-native, introduced species that hails from Europe.

It is a vine with yellow flower blooms that spreads aggressively and rapidly across the ground.

This plant is adapted to both sun and shade, and both upland habitats and wetland areas. It is a facultative wetland plant, meaning that it can function in wetlands with moist to wet soils.


What can you do?

Creeping Jenny spreads quickly along the ground and develops knotted root systems that are extremely difficult to remove! The earlier you catch it and begin removal, the less likely it is to gain a stronghold on your property. It is possible to be eradicated by hand, but requires complete removal of the roots.

 "Kids Don't Float...Give Them Something That Does."


Life Jacket Loaner Station
 

Just in time for Spring Break 2015 -- The Devils Lake Water Improvement District and the Lincoln City Chamber of Commerce Ambassadors held a rainy and windy Ribbon Cutting for the new LIFE JACKET LOANER STATION at Regatta Park on Devils Lake.  Spearheaded by DLWID Board Member Randy Weldon and developed in partnership with the Oregon State Marine Board, Oregon Corrections Enterprises, and Lincoln City's Park and Rec Department this station is the first of its kind on Devils Lake.


The Life Jacket Loaner Station is now stocked with life jackets of all sizes from kids to adult, which can be borrowed for use out on Devils Lake, swimming or wading in the lake, or out fishing on the docks. When in and around the water, safety is priority one, and this new station provides the greatest single tool to prevent accidental drowning directly to the public. The multi-lingual station also provides details on the properly fitting of life jackets in English and Spanish, and serves to educate all users of the lake the legal requirements that children 12 and under must wear life jackets at all times while boating.

 

What else is happening? A lot...from potential changes to the summer impoundment (aka the dam) to a lake wide aeration project...For all the details be sure to sign up for the monthly meeting materials or visit the Meetings Page of our website:  www.DLWID.org


Public Hearing Notice: The Devils Lake Water Improvement District will hold a Public Hearing as part of its April 9, 2015 meeting. The meeting will start at 6pm and will be held at Lincoln City Council Chambers, 801 SW Hwy 101, 3rd Floor, Lincoln City, Oregon 97367. The purpose of the public hearing will be for the board to take public input on the potential replacement of the impoundment structure otherwise known as the dam and the overall managed use and/or continuance of the District's Water Right Certificate 69267, Permit to Appropriate the Public Waters #52672, and Permit to Store the Public Waters #R-11968.  
Water Quality Monitoring begins
in May.



 
It won't be long until the District begins filling your inbox with weekly summer water quality reports!  

As usual, sampling will begin the week before Memorial Day and will run through Labor Day. The District monitors and samples for E. coli on a weekly basis...



...in addition to monitoring for Blue-Green Algae (cyanobacteria) as part of the Harmful Algal Bloom Surveillance program.   
 


The water quality results are then sent out via this listserv on weekly basis and posted at public access points around the lake.


We also sample for water quality indicators like temperature, pH, dissolved oxygen, turbidity, and electrical conductivity.

The Importance of Phosphorus

 

Phosphorus is essential for life on earth! For starters, this element 'is incorporated into many molecules essential for life such as ATP, adenosine triphosphate, which is important in the storage and use of energy. It is also in the backbone of DNA and RNA which is involved with coding for genetics' 1.  

  

    

  

'Phosphorus is a natural (e.g. not man-made) element that is found in nature in a finite supply'. The result of 'weathering and the erosion of rocks is the gradual release of phosphorus as phosphate ions which are soluble in water. When plant materials and waste products decay through bacterial action, the phosphate is released and returned to the environment for reuse' 1.     


 


 

   

 'Until the mid-20th century, farmers maintained phosphorus levels in soil by composting plant waste or spreading phosphorus-rich manure. Then, new mining and refining techniques gave rise to the modern phosphorus fertilizer industry-and farmers, particularly in the rich temperate zones of Europe and North America, who quickly became hooked on quick, cheap, and easy phosphorus' 2 .  

  

  

  

'Human influences on the phosphate cycle come mainly from the introduction and use of commercial synthetic fertilizers. Plants may not be able to utilize all of the phosphate fertilizer applied, as a consequence, much of it is lost form the land through the water run-off. The phosphate in the water is eventually precipitated as sediments at the bottom of the body of water. In certain lakes and ponds this may be redissolved and recycled as a problem nutrient.

  



Much phosphate eventually is washed into the water from erosion and leaching' 1.  This is an example of eutrophication 

  

Eutrophication is, "The process by which a body of water acquires a high concentration of nutrients, especially phosphates and nitrates. These typically promote excessive growth of algae. As the algae die and decompose, high levels of organic matter and the decomposing organisms deplete the water of available oxygen, causing the death of other organisms, such as fish.

"Eutrophication is a natural, slow-aging process for a water body, but human activity greatly speeds up the process "3  - Art, 1993   

  

  

  

'Aquatic plants and algae utilize the phosphate as a nutrient. Studies have shown that phosphate is the limiting agent in the growth of plants and algae. If not enough is present, the plants are slow growing or stunted. If too much phosphate is present excess growth may occur, particularly in algae' 1.

  

Eventually, not unlike all other living organisms, the life cycle of an alga (singular of algae), cyanobacterium or other form of HABs comes to an end and this end has consequences felt by all members of the aquatic ecosystem.

 

Bacteria and other types of microscopic organisms that live in aquatic ecosystems need oxygen just like fishes and humans do for respiration. Inputs of excess fertilizer and nutrients found in stormwater run-off are used by the microorganisms. Large inputs most often lead to large blooms.

 

When HABs die, bacteria and other decomposers use large amounts of oxygen to respire ("breathe") when breaking down HABs structures (cell walls, organelles, ...). This leads to anoxic (low oxygen) conditions that are not suitable for most species of fish and aquatic wildlife that are not adapted to live in these conditions.
