Issues

Jordanelle is a rather healthy lake. Its' Trophic State Index has ben consistently around 45 (in the middle of the mesotrophic zone) for the past five years. This, even though the flows into the reservoir have been quite different over that five year period.

  

 

 

 

 

 

 

 

Even though the Jordanelle reservoir is healthy we still see algae blooms occurring in the late spring and early summer as indicated in the Trophic State Table. The algae bloom in May correspnded to high phosphorus levels at the surface of the reservoir.

  

 

 

 

 

 

 

 

 

 

 

 

 

Surface temperatures in Jordanelle also raise during the summer months. Temperatures in both July and August of 2008 were above the State's Water Quality Standard.
