This site is on privately-owned land. The DNR obtains permission from the landowner(s) prior to conducting any sampling surveys.
Warm Water
Fair
Warm and sunny - air temp was approx. 70F. Water flow was near seasonal base flow level. Turbidity level was moderately heavy. Stream bottow visible to approx. 1.25'. The upper half of the sampling reach was impounded by a beaver dam. Sampling effectiveness was pretty good despite turbidity and a large woody debris jam in the middle of the reach.

FIBI Score Explained
Sites that score between 26 - 50 are considered fair. Fish abundance ranges from lower than average to very abundant. If fish are abundant, tolerant species are usually dominant. Native fish species usually equal ten or more species. The three most abundant species typically comprise two-thirds or more of the total number of fish. One or more sensitive species, long-lived fish species or benthic habitat specialists such as suckers (Catostomidae) are present. Top carnivore species are often, but not always present in low abundance. Species that are able to utilize a wide range of food items including plant, animal and detritus are usually more common than specialized feeders, such as benthic invertivore fish. Species that require silt-free, rock substrate for spawning or feeding are typically rare or absent. Fish condition is usually good; however, elevated levels of fish exhibiting external anomalies associated with disease or stress are not unusual.
This location has been classified as a Reference Site. Reference sites represent natural stream qualities that are least disturbed by human activities within the watershed. These sites are then grouped by ecoregion to establish a benchmark against which other streams in the same ecoregion are compared.
