North Branch Sunrise River Fecal<br />

Coliform Reduction Project<br />

The overall project goal is to reduce fecal coliform loading<br />

in the North Branch of the Sunrise River by 52%. The<br />

three primary sources are runoff from livestock, Imminent<br />

Health Threat (IHT) Septic Systems and pet waste. This<br />

319 grant with the accompanying Clean Water Legacy<br />

grant are the two primary funding sources being used to<br />

achieve this goal.<br />

SWCD staff from Chisago County contacted livestock<br />

landowners in both Chisago and Isanti Counties,<br />

explained the project, with permission visited farms, in<br />

consultation with landowners determined necessary<br />

modifications in practices (i.e. waste storage facilities,<br />

clean water diversions, vegetated filter strips, rotational<br />

grazing, livestock exclusions and nutrient management<br />

plans), offered available incentives, and monitor progress.<br />

Under this funding source no agricultural landowners<br />

installed practices to reduce fecal coliform loading.<br />

SWCD staff from Chisago County contacted citizens who<br />

live in urban areas and municipalities in the North Branch<br />

of the Sunrise River watershed. With permission, they<br />

visited citizens and city property to determine possible<br />

practices on their properties. Urban practices which were<br />

promoted are ones that increase water infiltration to<br />

reduce the peak flows in the North<br />

Branch of the Sunrise River, thus<br />

reducing high bacteria levels at large<br />

events. Eight rain gardens installed<br />

within the City of North Branch<br />

reduced TP by 4.8 pounds per year,<br />

TSS by 2,068.7 pounds per year, and<br />

volume by 4.22 acre feet per year<br />

from land areas that had limited to<br />

no treatment previously. The ability<br />

to account for bacteria reductions is<br />

not easily calculated, but based on<br />

available information if we reduced<br />

the total volume and TSS we should<br />

start to see some reductions in the<br />

watershed.<br />

Through Chisago County’s SSTS<br />

Pilot Program, both Chisago County<br />

and City of North Branch staff<br />

have inspected all SSTS within the<br />

Chisago County portion of the North Branch Sunrise<br />

River (NBSR) watershed. When IHT septic systems were<br />

identified, county or city staff worked with homeowners<br />

on the process required to bring their systems into<br />

compliance with the septic ordinance. The program was<br />

expanded into Isanti County to inspect all SSTS within the<br />

shoreland district and upgraded those systems identified<br />

as IHT.<br />

Pet waste receptacles were installed within North Branch<br />

city parks.<br />

Goals<br />

• Reduce Fecal Coliform from livestock<br />

• Reduce Fecal Coliform from IHT Septic Systems<br />

• Reduce peak flow from the City of North Branch<br />

Results that count<br />

• Under this funding source no agricultural landowners<br />

installed practices to reduce fecal coliform loading.<br />

• Three IHT septic systems were upgraded<br />

• Eight rain gardens were established in the City of North<br />

Branch<br />

Primary challenges<br />

1. Low landowner interest. A major challenge was<br />

the apparent lack of interest by landowners in<br />

implementing BMPs on their properties. This may<br />

have been a result of the worldwide recession. In<br />
