Data for Grygla

Very swift current, 2 beaver dams upstream. Upstream gate opened for reservoir drawdown.

Very swift current - upstream gate opened to allow reservoir drawdown.

Swift Current, high stage, infow from laterals, slumping and erosion up and downstream.

Swift current, 38 degF air temp, high channel level, lateral inflow leaking from capped culvert, evidence of weekend torrential rains.

MD point on downstream side of culvert. 2 beaver dams upstream of culvert.

Normal Flow - erosion and slumping downstream.

Low flow - significant erosion on bank downstream of bridge.

Low flow reveals significant slumping and erosion. Trees & shrubs growing on ditch banks - no natural buffering.

High flow, stable banks, cloudy, 74 degF, light breeze.

High level; cloudy, 73 degF, wind @ 10, very swift current prevented accurate bottom reading.

Tea colored, relatively high turbidity vs. clear t-tube reading. Mostly cloudy, wins @ 10, swift flow, minor bank erosion

Tea colored but clear, high turbidity reading inconsistent with t-tube reading. Mostly cloudy, light breeze, mid 70's, some bank erosion, moderate flow.

Slight rotting olor evident on road crossing, but not at stream level; 65 degF, moderate flow, clear water, laterals flowing significantly.

Stream gage: 4.9'; moderate flow, some greening, upstream ditches cleaned & fit with wier & check dams.

50% overcast, 62 degF, slight greening on buffer, erosion upstream, runoff from laterals. North lateral cleaned & shaped recently.

New road construction at crossing; re-shaped lateral ditches, new lateral culverts; vegetation cover on adjacent fields, little or no new greening; MCD20 shows significan slumps on embankments up and downstream; runoff coming from laterals.

Heavy rain recently, wind >30, higher flow than May, significant bank erosion upstream.

Heavy rain recently, wind <30, clear sky, higher flow than in May

3"-8" rain in past 72 hrs, wind <30, 82 degF, 20% clouds, low flow from culvert - gate closed or set high.

3"-8" rain in past 72 hrs, wind <30, noticed tiny invertebrates (worm-like) in sample water. 74 degF, 30% clouds.

Normal Flow, severe bank slumping downstream of site, clear sky, 62 degF, wind < 20, emergent vegetation.

Rotting smell in area. Beaver dam upstream of site. Water samples have strong rotting smell. Water is milky upstream. Conductivity was not captured.

Emergent vegetation, moderate flow, clear skies, 60 degF, wind @ 20

Slumping upstream of site, wind @ 20, 100% clear, 60 degF, moderate flow

No sonde measurements due to power failure. Brought sonde into field with proper recharging time. Low level, low flow. Ditches feeding into channel, vegetative debis in channel. Both upstream and downstream banks are adjacent to residential properties.

No duplicate sonde measurements due to instrument power failure. Large disparity between standard and duplicate samples in clarity and turbidity probably due to improper dip sampling. Visual indications are that the true clarity of the water is consistent with the lower turbidity value.

Low water level but measurable flow. Sample taken from downstream end of culvert

Very little flow, lots of vegetative debris, cattails in channel.

Very low water level, some bank erosion. Increased flow and greening of vegetation due to recent 3-4" rain.

Scummy surface, no persistent erosion.

Water is very low. Persisten erosion present from earlier flows.

Stream has little flow, low level. Algae and vegetative sediment in water. Ample buffer vegetation, no erosion.

Low water level, persisting erosion. Recent rainfall allowed some recent increase in level and restoration of vegetation.

Sunny & clear, no flow, no new vegetation, no rain

Minnows, abundant vegetation, low stream level, persistent stream flow

No perceptible flow, leeches in channel, lots of vegetation, normal stream level

Low flow, clear sky, 80 deg F, no breeze

Wire wt gage shows 1168.98 at surface, 1166.84 at bottom - channel depth 2.14 ft

Current is moving fast. Color appears cloudy when looking from surface

A lot more water

Low 50s - some bare soil and bank erosion

Water has a distinct odor

Milky but apparently swimmable. Staff reading 2.75'

Water is clear, but with floating organic particles - Manyu leeches - staff reading: 6.35

Increasing embankment failure near culvert: slumping, scouring - 100% clear, S wind @ 10

Current too swift for accurate bottom measurement;

Stream gage is 8.8 ; current too swift for accurate bottom measurement;

High water level, swift current

Elevated levels and swift current probably due to heavy rains from ~10 days ago.

Flow is too swift for bottom meas.; torrential rains from approx. 10 days ago are probable cause for elevated levels and swift current.

High flow due to earlier torrential rains.

High levels due to torrential rain approx. 10 days ago.

Water appears red in color

Flow is too swift for bottom meas.

Stream flow velocity too great to get reliable depth reading

Water is a darker tea color

Water is a darker tea color

Leeches

Lower than usual

river is high, but calm

river is high and foamy

River is very high and swift, water if foamy, water is being released

Very windy, water is mostly fclear and a tea-color to it

water is dark brown color, amber at edges, lots of minnows, muddy from the river, clear from the ditches

River is high and muddy, water from ditches is clear

water is foamy and mirky, a lot of minnows in water, ice still on the dike

River has a light brown, amber color, the water is flowing moderately fast
