Parts of the river, which cuts through Warren County, are too warm and lack an amount of aquatic life that's considered ideal, association says.

Parts of the Musconetcong River get too warm in the summer, lack the amount of aquatic life that's considered ideal and suffer from an eroding habitat.
These are among the findings in a report issued Tuesday by the Musconetcong Watershed Association. It is the first time the association has compiled such a report. The Watershed Institute and the Lake Hopatcong Foundation funded it.
The watershed affects parts of Hunterdon, Morris, Sussex and Warren counties. To compile data for the report, the association's river watchers analyzed conditions at four different points of the river during four different times of the year.
Two of those points were in Warren County - off Route 57 in Washington Township and near the Point Mountain Bridge in Mansfield Township. The report also did analyses off Willow Street in Roxbury Township, Morris County, and off Mount Joy Road in Holland Township, Hunterdon County.
The data, particularly at the upstream sites in Roxbury and Washington townships, shows there's a need to improve the river's overall water quality, the report says.

But while the ultimate goal would be optimal water quality at every stretch of the river, the report acknowledges that river advocates may want to set some more modest goals in the short term.
Here are some of the report's findings:
Roxbury Township: The average summer water temperature of 74 degrees is considered marginal; the aquatic life score, which looks at the number of organisms, is sub-optimal at 21; the habitat score of 145, based in part on soil erosion and river-bank stability, is sub-optimal; and the average level of nitrates in the water is optimal at 1 mg per liter.
Washington Township: The average summer water temperature of 72 degrees is sub-optimal; the aquatic life score of 19 is sub-optimal; the habitat score of 106 is marginal; and the average level of nitrates in the water is optimal at 1 mg per liter.
Mansfield Township: The average summer water temperature of 65.3 degrees is optimal; the aquatic life score of 26 is optimal; the habitat score of 159 is sub-optimal; and the average level of nitrates in the water is sub-optimal at 2 mg per liter.
Holland Township: The average summer water temperature of 65.3 degrees is optimal; the aquatic life score of 23 is optimal; the habitat score of 144 is sub-optimal; and the average level of nitrates in the water is optimal at 1.5 mg per liter.
According to the report, factors such as poor impervious cover and riparian buffers are affecting the numbers.
To improve the water, the report says, residents can take steps such as keeping tress and shrubs along lake and river banks, leaving grass longer on lawns near a bank, properly disposing of household chemicals and sweeping walkways rather than spraying them down with a hose.
The report also suggests that residents with septic tanks maintain them properly and asks that folks avoid removing rocks and boulders in waterways.
