Watersheds: Stream Assessment

Stream Assessment Field Training
Below is an example of results from the stream assessment training in Markel Run with the Watershed Alliance of Adams County. Typically, we would use RBP scores and information collected during the stream walk to help prioritize restoration recommendations; however, because this was a training example, we identified opportunities but did not rank them. |

Site # |
Description of Problem |
Recommendation |
|
1 |
Small channelized stream has no buffer, RBP score of 52 associated with this site |
Establish riparian buffer on both sides of stream |
|
2 |
Little or no buffer on both sides of stream, badly eroding banks, cattle in stream, RBP scores of 76 and 60 associated with this site |
Establish riparian buffer and cattle fencing on both sides of stream |
|
3 |
Little or no vegetation on banks, some trees in left bank, cattle in stream, trampling and erosion of banks, channel has recently been dredged and material deposited on banks, RBP score of 51 associated with this site |
Establish riparian buffer and cattle fencing on both sides of stream |
|
4 |
Little or no buffer on both sides of stream, cattle fenced into stream, RBP scores of 60, 36, and 92 associated with this site |
Establish riparian buffer and fencing to keep cattle out on both sides of the stream |
|
5 |
Bank vegetation mostly grass, a few trees, is relatively stable, cattle in stream, some trampling and erosion and slumping primarily on right bank, runoff from lagoon causing water quality issues |
Establish riparian buffer and fencing to keep cattle out on the entire right bank and on the left bank on the lower half of the reach. Look into lagoon runoff issue |
In
additon to mapping analysis, field assessment of on-the-ground conditions
and the identification of restoration opportunities requires getting
your feet wet. While there are many stream assessment techniques available
for watershed organizations, we typically use the EPA's
