Local Water Quality Issues
A number of studies have been conducted in the Cub River Watershed. Based on the available water quality monitoring data, water quality problems were
identified including, stream bank modifications, confined feeding operations, over utilized pastures, freeze thawing of stream banks, sheet and rill erosion, classic and ephemeral gully erosion, irrigation induced erosion and stream bank erosion.
Cub River has a SVAP aquatic habitat score of fair to poor, good stream bank stability and slight erosion. It appears that irrigation structures affect the streams ability to transport the sediment load. Lack of riparian vegetation is also a factor in the low habitat score because upland vegetation cannot hold banks together to have overhanging banks to provide woody debris for fish and invertebrate habitat.
Worm Creek has a very low SVAP habitat score, great stream bank stability and moderate erosion. Glendale Reservoir acts as a sediment trap. This restricts the ability of the stream below the Dam to develop point bars (which are good indicators of stream health).
The Franklin Soil and Water Conservation District (FSWCD) worked with landowners to install a bioengineering demonstration project on the Cub River. The demonstration showed how to do minor stream restoration. The FSWCD is also implementing a 319 grant restoring eroding banks on the Cub River. The Natural Resource Conservation Service has also implemented projects along the Cub River, Worm Creek and Maple Creek. Implementation of BMPs on the Cub River has shown a 6% reduction in annual average soil erosion. For more information see the Cub River Watershed Agricultural TMDL Implementation Plan
