Winter
2016
Oh, the weather outside is frightful!
   This year has been a busy one for the Devils Lake Water Improvement District. Between new faces in the office and on the board, and the progress that has been made on projects, the atmosphere going into the new year is full of excitement and hope. 2016 is sure to bring another great year on our beloved Devils Lake!
What's going on at Devils Lake Water Improvement District? 
  • Only the biggest potential project ever on Devils Lake....Whole Lake Circulation using Vigorous Epilimnetic Mixing (VEM), or more simply put a form of Aeration!
At the District's January 14, regular meeting Dr. Alex Horne and HBH Consulting Engineers will introduce a potential aeration project for reducing Harmful Algal Blooms.   Dr. Horne would potentially design the project and with the help of the Newberg, Oregon based engineering firm, get the project ready for permitting and bidding.

Aeration is much like it sounds...."Tiny Bubbles", used to move water from the bottom depths to the surface. At the surface the water mixes with the atmosphere fully oxygenating the water which then cycles back to the bottom.
 
"Tiny Bubbles" in the form of Vigorous Epilimnetic Mixing (VEM) can move more than just water.  Blue-green algae, the nuisance, often toxic kind, also circulate disrupting a primary evolutionary trick they have over "good algae" which is the ability to be float to the surface.  Circulating the "bad algae" along with the the "good algae", levels the playing field for which these microscopic organisms compete for sunlight and nutrients.

Sample Similar Project:  

"It may be oxygen bubbles to the fish, but its champagne to us."  William P. Ruzzo, and Robert McGregor,   Colorado Lake & Reservoir Management Association, Newsletter 2008

Got questions for Dr. Horne and HBH about Vigorous Epilimnetic Mixing (aka Aeration) in Devils Lake?  

Submit them to the District in advance, so we can compile them for our meeting.  There will be additional time at the meeting for questions, but the more we can ask in advance the better.  
  • Email your questions by January 7, 2016 to lake.manager@DLWID.org with the subject line:  Aeration
  • Then come to the meeting on January 14, 2016 6pm at City Hall, watch it on Channel 4, or stream the meeting to your computer.

Native Species Spotlight    

   Although its the middle of winter and a blooming garden is months away, this is still an important time to be out in your garden! Pruning is an important step in ensuring a colorful and vibrant garden in the spring. Make sure to clean up your garden to provide a fresh place for new buds to grow.

Benefits of planting native:
  1. Using locally native plants can ensure habitats for other local plants and animals that depend on them, like butterflies.
  2. Native plants are BEAUTIFUL!
  3. Locally native plants are adapted to local soil and climate conditions, making many of them easier to maintain and care for.
  4. By using locally native plants, you reduce the risk of introducing invasive plants into your community.
  5. By using LOCALLY native plants, rather than natives from other parts of Oregon, the unique genetic makeup of locally native plants will not be altered.

This season you should plant: Red Twig Dogwood!

Red twig Dogwood or Cornus sericea is a gorgeous native that offers beauty during every season. During the winter months it provides a vibrant red color to your garden and in the spring it produces a white flower and a blue berry that will bring a variety of wildlife into your yard! This shrub is ideal in wet soils (perhaps near the shoreline) and can tolerate seasonal flooding. This is an excellent plant to add this winter.

Limnology 101-The Resilient Coho
   In last quarter’s Limnology 101 we learned the history of Chinese Grass Carp in Devils Lake and how they are used as a biological control of aquatic vegetation.  
  
   This quarter we are going to talk about our favorite local, the coho salmon. We will learn about their unique life cycle and how Devils Lake and its surrounding watershed plays a critical role in their development and survival. 

   The coho salmon ( Oncorhynchus kisutch) is one of several species of Pacific salmon. It is also known as the silver salmon or white salmon.  The Oregon Coast is home to a threatened population, recognized by the U.S. National Marine Fisheries Service.  
   Coho are hatched in the gravel of streams and rivers. They start as small alevins with large eyes and an orange colored nutrient sack attached to their underbellies. They will continue to live in gravel for protection. After about 4 months, the alevins will transition into the fry stage. This stage brings the coho to a whopping length of about 1 inch. They leave their gravel nests and will live in lakes and slow moving streams for about a year before blossoming into a smolt and migrating to the ocean.

   There is a stage in-between fry and smolt, called parr, where the salmon develop dark vertical markings on their sides which helps them camouflage and hide from predators.  When the salmon are ready to head out to sea, their gills begin to transition for salt water and the fish lose their dark markings and turn silvery in color. This is the stage where our local population of salmon have a unique habitat. Devils Lake provides a last stop habitat for the fish to grow even bigger and stronger. In the ocean their diets will shift from plankton and insects in fresh water habitats to small fish in the ocean. After only about 18 months the smolts will have transitioned into adults and start their journey back to the stream or river they were hatched in order to reproduce themselves.   
    The migrating adult stage turns the salmons a bright pink/red color. The journey they must endure is a difficult one, and it can be made even more difficult by human practices. There are a wide variety of obstacles that they face. First, when the migration starts the salmon stop eating and rely on their stored body fat. For those that do not have enough, they will likely starve to death. Many salmon will have to swim up through polluted waters near urban environments. Bears, otters, and eagles love this time as salmon make up a delicious part of their diet. The fish not only have to contend with their natural predators, we have become an aggressive threat to their journey with large nets and fishing practices at every level of their journey. People have also built large obstacles that are more than often difficult to navigate. Dams have long proved to be devastating to salmon. The salmon who face dams (which almost every single one does) are expected to jump over a straight cement wall that can be much taller than their jumping range. Making things even more difficult, the water on the downstream side of dams is often too shallow for coho to get enough momentum for their best jumps. Fish ladders and elevators are used to aid the salmon over the more dominant dams. Where fish passage is not provided, the spawning habitats beyond will be permanently blocked. On Rock Creek, the District in collaboration with the Salmon Drift Creek Watershed Council, City of Lincoln City, USFWS and ODFW,has been able to transform an old municipal dam that was no longer in use and causing problems for local salmon, into a passable dam for salmon and still allows for human use if it is needed. It is important to manipulate our usage of the environment to ensure that our natural resources survive.
   Why are we so concerned with the survival of one species of fish? Salmon play a vital role in the environment and the economy. In some areas, the Salmon is the center point for culture and prosperity. Coastal communities have long depended on the fisheries industry for both protein and income. In 2012, Oregon fishing vessels brought in 307 million pounds of fish which valued in at about $126.4 million. They also are an active representative to many tribal communities along the Pacific Coast. In many native legends and myths salmon have been reported to have sustained one of the largest native populated areas of North America. Far and wide, the support for conserving salmon populations can be heard. The salmon is a major value to Oregon and its communities.

   There are many ways that can help improve salmon populations. The primary being the improvement and sustainability of their freshwater habitats. Adding vegetation in our lake provides cover from predators in the water, and putting large wood and other coverage back in the rivers. This can create deeper channels and cooler water which will help the salmon in the difficult migration they face. Another movement that needs support is continued work on eliminating obstacles, like the dam on Rock Creek, that can make rivers largely impassable. 

   The population of coho salmon that live in Devils Lake are a prize to the community.  Their annual migration is a spectacle to be seen in the World's Shortest River between Halloween to Valentine's Day.  Regionally these fish provides for us by keeping our stomachs full and putting cash in our pockets. However because of our impacts, many of the salmon's habitats have been compromised and the duty of rectifying the disastrous outcomes rests in our hands.   Read NOAA-Fisheries Proposed ESA Recovery Plan for Oregon Coast Coho Salmon    
Maintaining Your Septic Tank
   With the number of septic tanks that are around Devils Lake, it is important to maintain them as best as possible. The District strongly encourages everyone to get a septic tank inspection to ensure that there are no failures in your system. Septic systems and their drain fields are only made to last around 25-30 years. This means that as our homes are getting older, it is likely that septic tanks are needing tuning up or even replacement. What does it mean to have a septic tank fail? It means that, either through a damaged tank or a super-saturated drain field, inadequately treated waste can leach into our ground water and sometimes reaching the surface, exposing the community to harmful bacteria and viruses. The excess nitrates and phosphates in domestic water also will be introduced to ground water and the lake which feeds algae and other lake vegetation.
   If your tank and field are still in good health there are some strategies to get the most out of your system, and have it last for as long as possible:  
  1. Locate your tank and drain field. This will become important when it comes time to get an inspection or pump-out.
  2. Get your septic system checked regularly. This ensures that you catch any potential failures as quickly as possible and therefore potentially saving costly repairs down the road.
  3. Get it pumped. It is important to get your tank pumped in timely intervals.
  4. Conserve water. This will avoid overloading your system.
  5. Divert excess water. Whether it is from rain gutters or hot tubs, it is important to keep keep excessive amount of water away from your drain field soils so they can naturally treat waste water effectively.
  6. Don't use your toilets or sinks as trash cans. Trash can clog your pipes and will not necessarily decompose in the septic tank. This takes up valuable space and can quickly cause failures. DO NOT pour chemicals or harmful cleanser down the drain. These can easily kill the hard working bacteria in your system.
