Nissen Reservoir 

Nissen Reservoir #2, was part of the Nissen/Zang Reservoir system established May 5th 1889.  The system was created to irrigate the farms of August Nissen and Adolph Zang, they also sold water shares to neighboring farmers.  Constructed between 1900-1910 Nissen Reservoir was originally a single reservoir of approximately 35 surface acres around 12' deep.

In the early 1960's Broomfield Country Club Golf Course was built, Nissen #2 became water source to irrigate the course. The reservoir had an abundance of aquatic plants and water so clear the bottom was visible at its 12 foot depth.  In and around the lake it was common to see muskrats, turtles, leopard frogs, salamanders  and many bull and garter snakes.  The fishery contained Large and Smallmouth Bass, Blue Gill, Sunfish, Perch, Crappie and crayfish.  The abundance of food drew Coyotes, Raccoons, Raptors  and the occasional weasel searching for a meal.  It was a haven for migratory birds, water fowl, and the nesting ground for many species.  

With the expansion of the Golf Course in 1982, Nissen Reservoir was drained and divided (still connected by a culvert) reducing the surface area to approximately 28 Acres.  Though never returning to its former aquatic health, the Habitat supports an abundance of wildlife, aquatic life, and many species of birds. 

Nissen Reservoir continues to be the only source of water to irrigate the Eagle Trace Golf Course.  It is filled from Farmers Reservoir and Irrigation Company (FRICO) ditch and water is pumped from reservoir to the course irrigation system.   

Nissen Reservoir #2 is the 2nd largest area of surface water in the City and County of Broomfield (measured by Google Maps).  Nissen has been a historic water source and an irreplicable inner city wildlife habitat benefiting the Broomfield Community for over 100 years.
