(3) N-2 Lower Naturita Creek
Surface Water Monitoring Station
(a) Monitoring Schedule (post TR-06):
(i) Field parameters semi-annually.
(ii) Annual fall full suite list 2.
(b) Monitoring station N-2 was monitored in 1988 four
times for the full suite list 2. In the fourth
quarter of 1988 they did not monitor the pH and the
conductivity.
In the 1st quarter of 1995 the Creek was reported as
dry at station N-2.
In the 4th quarter of 1995 a revised monitoring plan
went into effect, under TR-06. This eliminated the
need for the monitoring of station N-2 during the
4th quarter of 1995. For purposes of comparison
with baseline water quality data from 1988, the 4th
quarter of 1994 will be included along with the 1st,
2nd, and 3rd quarters of 1995.
