Lower Yamhill River Water Quality for Fish Habitat

Yamhill Water Quality CIS

 

 

 

 

 

 

 

 

 

 

 

County or Counties: Yamhill

Primary Resource Concern Addressed: WATER QUALITY DEGRADATION - Excessive sediment in surface waters
 

Project Description

Local work groups and the Yamhill Soil and Water Conservation District have identified Water Quality affecting fish habitat as a high priority resource concern. Sediment in runoff from cropland affects habitat for fish, including ESA-listed salmonid species. Sediment carries nutrients, especially phosphorus, and organics into the river. This in turn leads to low levels of dissolved oxygen due to algal blooms and increased biological oxygen demand. Inefficient irrigation systems result in low summer streamflow which also decreases dissolved oxygen levels. The Yamhill SWCD has laid an excellent foundation for sediment control and irrigation efficiency, especially with crop farmers in the lower Yamhill River. This CIS focuses on reducing sediment runoff and increasing stream flows in the lower Yamhill River and its tributaries, thus improving habitat for fish.

Local EQIP Ranking Questions

NRCS uses these questions to evaluate eligible applications for this project and to prioritize applications for potential funding. State and national ranking questions also apply. See more information on the EQIP program page.

Screening Questions

  1. Are 100% of the acres to be treated within the focus area and will practices reduce the runoff of sediment? (high priority)
     
  2. Are 100% of the acres to be treated within the focus area and will practices increase summer flows in focus area streams (but not address sediment runoff)? (medium priority)
     
  3. Are any acres to be treated outside the focus area? (low priority)
     
  4. Does the producer have a current or past Farm Bill Program contract and does the NRCS case file document that the producer was unresponsive to three or more requests for information or signatures? (low priority)

 

Ranking Question

Points

Will planned practices reduce sediment delivery by 20% or more as predicted by RUSLE2? 200
Will buffers of native vegetation (herbaceous or trees and shrubs) be installed at least 20-feet wide on at least 25% of the stream reaches in enrolled tracts? 50
Will buffers of native vegetation (herbaceous or trees and shrubs) be installed at least 35-feet wide on at least 25% of the stream reaches in enrolled tracts (also scores points for #3). 50
Will the project include a structure to capture sediment (includes seeding ditch banks)? 50
Will planned practices increase the annual water savings estimate by 15% or more? 50
Are you applying more tha 40 lbs-ac of phosphate (P2O5) and will Nutrient Management be a part of the contract? 50
