East Fork Lake – HAB History
• HABs first samples/microcystin first detected in 2012‐peak 4.5 ppb at main beach
• First advisory in 2013– peak microcystin 88 ppb

StreamNetwork• Need to know what’s influencing water quality in the lake?• Coupled monitoring and modeling efforts• Ambient grab samples and automatic samplers for event based monitoring
• Flow data for load calculations• Flow meters at automatic samplers, acoustic doppler flow meter for grab sampling
• Sampling locations• Large # of stations from headwater streams to East Fork at HUC boundaries. Frequency and parameters vary.

Landscapes:FromMonitoringtoImplementation• Modeling of the watershed pinpointed the sectors contributing the highest loads to the lake
• SWAT modeling still needs validation data from nonpoint source loading and the impact of BMPs
• US EPA SWAT model used to project high areas of sediment yield (rust colored area)
• SWCD/NRCS/FSA, work with producers to put practices on the ground
• Special EQIP – Five Mile Creek Watershed• Conservation Innovation Grant – cover crops &
detention basin/vegetated bed system• Recently awarded RCPP grant
• County monitors practices 18

ConservationInnovationGrant• 2011 secured USDA Grant to design, implement & monitor an innovative BMP to reduce nutrient runoff from farms
• Cooperative Effort• SWAT model helped secure the funding• SWCD & USEPA designed the system• Strong relationships with local farmers secured to BMP location

• Composite nutrient sampling
• Flow monitoring• System is working!
• 49% nitrates• 27% organic N• 37% DRP
• Goal:• Removal efficiencies?• Cost effective• Get adopted as an EQIP
approved practice.22

Conclusions
23
• Partnerships allow for data sharing and better resource allocation• Documented historical changes in
water quality and coincident shifts in algal communities.
• Establish a water monitoring infrastructure that facilitates focused research studies & the development, testing, and validation of models .
• Conducted outreach opportunities using an ‘Ambassador’ approach: increased BMP adoptions
• Projects of this scale are impossible without all the partners
