Field parameters, except flow in the Upper North Fork o! fhe Gunnison River monitoring point are taken on the rivarjust above its mn9uence with
Hubbard Creek. Flow data !or the North Fork 0! the Gunnison river is obtained lmm USGS station #09132500.
Baseline Inforraeon for Point NFGup is derived from events beginning on 8/3056 through 3/3187.
Point inguenoed by mining on 35187.
