Annual Activity Sheets from 'A Day in the Life' Student collected data

Starting in 2009 worksheets and educational materials have been developed focused on the data students collect at their sampling sites. Comparing between years shows a dynamic system that adjusts with changes in conditions. Be sure to review the metadata with your students as this will add the context they need to be successful in using the data.

10/20/16 - Our fourteenth annual event found the estuary very dry with the saltfront pushed well upriver, in fact the leading edge of the saltfront was pushed further upriver than we have found it over any of our previous Day in the Life events. Thunderstorms threatened the area and the upriver sites did see rain for part of the day. Turbidity was low as the lack of rain slowed nutrients and sediments from moving downriver, and salt-loving fish, like the bluefish were found well upriver at RM60.

10/20/15 - Our thirteenth annual 'Day in the Life of the Hudson River' the day was crystal clear and dawned cool. Little rain had reached the estuary for the last month or more and so influences from the salt, entering at from the Atlantic Ocean at the southern reaches of the Hudson, were found well upriver. Atlantic Silversides, an ecological indicator of the leading edge of salt in the estuary, were netted up by Beacon and Newburgh (RM60). One surprise was the saltwater loving pipefish that made its way as far up as Norrie Point (RM84.5) where the water was well below what we would consider brackish.

10/16/14 - The weather was poor for much of the lower river with torential rains and thunder and lightening in some areas.. Many sites contacted us cancelling or postponing. We ended up supporting as many schools as possible with make up events. It turned out the storm went on for several days and so even make up events were rescheduled or held in difficult weather conditions. We accepted and posted data from any number of different dates in the two weeks around the event date.

Fishing in 2013
10/10/13 the weather threated rain after a fairly dry August. Most sites were able to sample without

ulsterA second straight year saw salt move up beyond Newburgh.

The day was cold, averaging a full 10 degrees Celcius colder than 2012.
seineCool temperatures may have contributed to very low fish counts. Many sites netted nothing. Tides, Plants? Overall fish counts were down - several sites had empty nets where in past years they had netted fish. In many areas the tides were at the high end of their range, making seining difficult. In the upriver freshwater sites lack of vallisneria (water celery) might have contiburted to low counts of fish as small fish use these beds for protection & foraging.

Day in Review

10/4/12 The week leading up to the event was wet, although the summer had been very dry.



RiverHeavy mist and rain covered much of the Hudson during the day. Some schools postponed - most participated.

SalinityThe salt pushed way upriver to Poughkeepsie.


Water plant vallisneria (water celery) was mostly absent post hurricanes.

CrotonThe salt front was low, pushed down by all the rain.

Day in Review
10/14/10 the day began shrouded in fog and for the afternoon samplers ended in rain. and the salt front pushed down to ~ RM 36 - about half where it was in 2009.

The weather was cool and crisp.

Recent rains throughout the watershed had left the river running very full.

10/8/09 a 'blow out tide' greeted samplers. Strong winds on the Hudson began midday 10/7/09, strengthening during the night.

The strong wind affected tides causing a 'blow out' or extremely low tide exposing large expanses of mudflats.

Fish catches were poor. Salt levels dropped with a rain on 10/7/09.
