Levee Breeches

Work was started on the installation of flow control structures in the levee breeches in 2015.

The permit requires that barriers be installed to allow flow at levels over 579 feet to protect neighboring properties. Water is now at 579-3/4 ft. but it should be down in 2016 because an El-Nino winter is forecasted.

Celery Flats Remediation

When the Annis Water Resources Institute conducted a study on the Mona Lake Muck Fields, aka, the “celery flats” (see map) we expected alarming news because we could see massive algae blooms oozing into Black Creek just upstream from Mona Lake (see photo). The analytical results were worse than expected. The graph right is from Dr. Steinman's presentation addressing the study. It depicts total phosphorus (TP) in the water column among area water bodies.

Celery Flats MuckNote how much higher the Muck Field TP results are on the graph then Mona Lake TP levels. Phosphorus levels in the flats are astronomically higher than what is considered biologically healthy.

The muck fields are shallow ponds, with an average depth of 1-3 feet. They were wetlands converted to celery production in the early 1900s. When the pumps that kept the fields dry stopped, the area flooded, and the nutrient-rich soils became a feast for blue green algae. The wetland system that would normally keep phosphorus in check was disrupted over a century ago and it has not been able to rectify itself. Reclaiming the healthy function of this wetland system is a major priority in the Mona Lake Watershed Plan.
